Section 01

Why this paper exists

The emergence of Large Language Models — and their rapidly advancing reasoning capabilities — marks a fundamental shift in how businesses interact with information, software and operational systems.

Unlike conventional software, which primarily follows predefined rules and structured commands, LLM-powered systems can interpret natural language, connect information, generate contextual responses and support reasoning across complex business situations. This creates opportunities to make business systems more intelligent, accessible and responsive.

However, the rapid growth of AI has also created considerable noise. Technical complexity, exaggerated claims, disconnected AI tools and unclear terminology make it difficult for organisations to distinguish genuine business value from temporary hype. Simply adding a chatbot or connecting an LLM to existing software does not make a business system AI-ready.

This paper exists to bring clarity to that landscape.

It explains how businesses can thoughtfully adapt their systems, data, processes and governance to use modern LLMs effectively. The objective is not to promote AI adoption for its own sake, but to establish a practical foundation for applying AI where it can produce meaningful, reliable and measurable business outcomes.

What an AI-ready business system requires

Building an AI-ready business system requires more than technology. It requires:

  • Well-structured and contextually meaningful business data
  • Clearly defined processes and operational boundaries
  • Secure access to organisational knowledge
  • Reliable integration between AI and existing systems
  • Human oversight, governance and accountability
  • Continuous evaluation of accuracy and business value

This paper provides a structured path for understanding these requirements. It helps business leaders, solution architects, technology teams and decision-makers evaluate where LLMs can be useful, what must be prepared before implementation, and how AI capabilities can be introduced responsibly.

The Central Question

The central question is therefore not simply:

How can we add AI to our business software?

It is:

How can we prepare our business systems to use AI intelligently, securely and purposefully?

That distinction forms the foundation of an AI-ready business system — and the starting point of this paper.

Section 02

The universal foundation of an AI-ready business system

An AI-ready business system is not simply an existing application connected to a Large Language Model. It is a governed environment in which organisational knowledge, user identity, secured access, purposeful retrieval and LLM intelligence work together as one connected capability.

This foundation must remain independent of any particular industry, software platform, communication channel or AI model. It should be equally applicable to a public knowledge assistant, an employee support system, an ERP intelligence capability, a customer-service companion, a decision-support solution or a specialised business application.

At its centre is a simple but powerful relationship:

Persistent business knowledge must be securely accessible to the right person, intelligently retrieved for the right purpose, and meaningfully interpreted by an LLM.

The Architecture

The foundational architecture

Six responsibilities, held apart on purpose. Knowledge supplies the business truth; identity and policy decide what may be reached; retrieval assembles it; the model reasons over it and nothing else.

  1. 01 Actor with a defined purposeA person or system with a legitimate business reason to ask.
  2. 02 Communication gatewayThe website, application, WhatsApp, email or API carrying the request.
  3. 03 Verified identity and interaction contextWho they are, what they may see, and where the request came from.
  4. 04 Persistent organisational knowledgeThe business truth, held independently of the model.
  5. 05 Access policies and knowledge classificationsThe rules that decide what may be reached, and by whom.
  6. 06 Secured, purpose-aware retrievalAssembles only the authorised, relevant evidence for this interaction.
  7. 07 LLM intelligenceReasons over the supplied evidence — and over nothing else.
  8. 08 Grounded response or assistanceAn answer traceable to its sources, or an acknowledged limitation.
  9. 09 Delivery through the appropriate channelReturned to the actor in a form suited to that channel.
Identity, knowledge and policy converge on retrieval. Only what retrieval authorises reaches the model.

Responsibilities

  • Organisational knowledge provides the business truth.
  • Identity and policy controls determine what may be accessed.
  • Retrieval identifies and assembles the relevant authorised knowledge.
  • LLM intelligence interprets that knowledge and formulates a meaningful response.
  • Communication channels connect people to the shared capability.
  • Business purpose governs the entire interaction.

These responsibilities must remain distinct. The LLM should not become the source of organisational truth, the authority that grants access, or the system that independently determines business policy.

The elements of the foundation

01Business purpose comes first

Every AI capability must begin with a clearly defined business purpose. The purpose may be to help someone:

  • Discover available information
  • Understand a business situation
  • Locate a document or record
  • Explain a policy or process
  • Summarise complex information
  • Compare available options
  • Analyse operational information
  • Support a decision
  • Receive guided assistance
  • Escalate a matter to the appropriate person

The business purpose determines the required knowledge, the permitted users, the expected response, the appropriate channel and the acceptable level of risk. This leads to an essential principle:

AI readiness begins with clarity of purpose — not with the selection of an LLM.

A technically advanced AI implementation without a defined business purpose may produce impressive interactions but limited operational value.

02Persistent organisational knowledge

An LLM can interpret language and connect information, but it does not automatically understand the current truth of an organisation. Business knowledge must therefore exist independently of the LLM in a persistent, maintainable and retrievable form.

This knowledge extends far beyond documents.

Documented knowledge

Policies, procedures, manuals, contracts, product information, service descriptions, technical documentation and regulatory guidance.

Operational knowledge

Information maintained in ERP, CRM, HRMS, project-management, finance, inventory and other transactional systems.

Contextual knowledge

The relationships between customers, employees, suppliers, departments, projects, products, transactions and business activities.

Conversational knowledge

Relevant information from earlier interactions may provide continuity, provided that it is retained with appropriate consent, security and purpose limitations.

Derived knowledge

Summaries, classifications, calculated indicators and previously generated insights may also contribute value when their sources, validity and limitations are clearly established.

Authorised external knowledge

Some purposes may require current information from approved external sources. Such information must be distinguished from internally governed organisational knowledge.

For knowledge to remain dependable, it should have:

  • A recognised source
  • Clear ownership
  • Appropriate classification
  • Version and validity information
  • Relationships with relevant business entities
  • Defined access conditions
  • A process for correction and updating
  • Traceability to its origin

Persistence means that knowledge survives beyond an individual conversation, model session or communication channel. Changing an LLM should not result in the loss of organisational knowledge.

03Identity, trust and secured access

The usefulness of business knowledge does not mean that it should be universally accessible. Every interaction involves an actor. That actor may be an unidentified public visitor, a verified customer, an employee, a manager, a supplier, a business partner, an administrator, or another authorised system or AI capability.

The system must understand more than a name or login. It may need to establish:

  • The person's verified identity
  • Their organisation or business unit
  • Their role and relationship with the organisation
  • Their department, project or customer association
  • Their permissions and delegated authority
  • The communication channel being used
  • The sensitivity of the requested information
  • Whether additional verification or consent is required

Together, these factors create an identity and trust context.

This makes it possible for the same intelligence capability to serve many types of users without crossing organisational, departmental, customer or confidentiality boundaries.

04Purpose-aware retrieval

The retrieval capability forms the controlled bridge between organisational knowledge and LLM intelligence. Its role is not merely to find text containing similar words. It must understand the request in relation to:

  • The intended business purpose
  • The identity and permissions of the actor
  • The current interaction context
  • Knowledge classifications
  • Relevant customers, projects or transactions
  • The source and validity of the information
  • Defined business and security policies

Retrieval may combine multiple methods, including semantic search, keyword search, metadata filtering, structured database queries, entity and relationship matching, business classifications, and date, status and validity conditions.

The result should be a carefully assembled authorised evidence context containing only the information relevant and permitted for that interaction. Good retrieval reduces irrelevant information, prevents unauthorised exposure and gives the LLM a reliable context within which to operate.

05Purpose-aware LLM intelligence

LLM intelligence is the capability that interprets the person's request and the authorised knowledge supplied to it. Within this component, the model may understand natural-language requests, recognise intent, interpret retrieved information, connect related facts, explain complex material, summarise relevant evidence, compare options, formulate a contextually appropriate response, and identify when available information is insufficient.

Reasoning belongs within this LLM intelligence capability. It is not a separate source of knowledge, security layer or policy authority.

The LLM does not own organisational knowledge or determine access rights. It reasons only over the authorised knowledge and business context provided for a defined purpose.

When reliable information is unavailable, the system should not compensate with confident but unsupported language. It should request clarification, acknowledge the limitation, provide a controlled fallback or escalate the interaction to a human.

Does this foundation require model fine-tuning?

This foundation does not depend on model fine-tuning. Its primary requirements are:

  • Well-prepared organisational knowledge
  • Purpose-specific instructions
  • Identity and access controls
  • Contextual retrieval
  • Response boundaries
  • Source grounding
  • Evaluation and feedback

Fine-tuning may later be useful for stable domain terminology, specialised classifications or highly consistent response behaviour. However, it should not be used to store frequently changing business knowledge, enforce permissions or replace secured retrieval. The foundation should remain effective even when the underlying LLM is changed or upgraded.

06Identity-aware communication channels

People may access business intelligence through websites, customer portals, internal business applications, ERP or CRM interfaces, mobile applications, WhatsApp, email, voice interfaces, APIs and future communication environments.

These channels should not maintain separate and conflicting knowledge or intelligence systems. They should operate as controlled gateways into the same governed foundation.

Each channel contributes important interaction context:

  • Where the request originated
  • Whether the person is identified
  • How identity was verified
  • What session or conversation is active
  • Which response format is appropriate
  • What security limitations apply to that channel
  • Whether the interaction can safely continue there

A website visitor, verified customer and internal employee may ask an apparently similar question. However, the retrieved knowledge and resulting response may differ because their identities, relationships, permissions and purposes are different.

The channel carries the interaction. It does not independently decide the truth, the permission or the intelligence.

07From request to meaningful assistance

Every interaction should follow a governed sequence.

  1. AActor
  2. CChannel
  3. RAccess and retrieval
  4. KOrganisational knowledge
  5. LLLM intelligence
  1. 01 Actor sends to Channel Request with a business purpose
  2. 02 Channel sends to Access and retrieval Identity, channel and interaction context
  3. 03 Access and retrieval acting on itself, then Access and retrieval Verify identity and apply access scope
  4. 04 Access and retrieval sends to Organisational knowledge Retrieve permitted and relevant knowledge
  5. 05 Organisational knowledge returns to Access and retrieval Source-grounded business evidence
  6. 06 Access and retrieval sends to LLM intelligence Request, purpose, evidence and boundaries
  7. 07 LLM intelligence returns to Access and retrieval Contextual response
  8. 08 Access and retrieval acting on itself, then Access and retrieval Validate grounding and response boundaries
  9. 09 Access and retrieval returns to Channel Approved response and supporting evidence
  10. 10 Channel returns to Actor Meaningful answer, assistance or handover

Identity is established before knowledge is retrieved, and grounding is validated before anything reaches the actor.

Depending on the purpose, the result may be a grounded answer, a clear explanation, a summary, a comparison, a recommendation, guided assistance, a request for additional information, or a controlled human handover.

08Evidence, accountability and continuous improvement

A trustworthy business system must be able to explain the basis on which information was provided. Where appropriate, the system should retain:

  • The identity and interaction context
  • The purpose of the request
  • The knowledge sources retrieved
  • The access policies applied
  • The response produced
  • Relevant confidence or quality indicators
  • Whether clarification or human intervention occurred
  • User feedback and corrections
  • The resulting business outcome

This does not mean exposing or storing the model's private internal chain of thought. It means preserving the operational evidence required to evaluate security, grounding, accuracy and business effectiveness.

Classification

A universal classification for diverse purposes

Because this foundation must support many industries and applications, every use case can be described through a common classification — which allows diverse AI use cases to be compared without forcing them into a single application design.

DimensionGoverning questionExamples
PurposeWhy is intelligence being used?Discover, understand, explain, analyse, recommend or assist
ActorWho is interacting?Visitor, customer, employee, partner, administrator or authorised system
Knowledge scopeWhat information may be considered?Public, internal, confidential, customer-specific or restricted
ChannelHow is the interaction taking place?Web, business application, WhatsApp, email, voice or API
Intelligence boundaryWhat may the LLM do?Interpret, summarise, compare, explain or recommend
OutcomeWhat should the interaction produce?Information, guidance, decision support, clarification or handover
Risk and controlWhat safeguards are required?Verification, source grounding, approval, audit or human intervention

The Foundational Principle

For every legitimate business purpose, the right actor should be able to access the right organisational knowledge, through an appropriate and secure channel, and receive intelligence grounded only in the context they are authorised to use — with evidence, security and accountability maintained throughout.

This principle separates a genuinely AI-ready business system from a conventional application that has merely been connected to an LLM. It also establishes the foundation on which the remaining sections examine architecture, knowledge preparation, identity, retrieval, communication channels, implementation patterns and maturity — without becoming limited to one industry, one platform or one generation of AI technology.

Section 03

Putting LLM intelligence to work

Reasoning over governed business knowledge

The foundation described in the previous section prepares organisational knowledge, identity, secured access, retrieval and communication channels. However, preparation alone does not create business intelligence.

The practical value emerges when the capabilities of a Large Language Model are applied to authorised organisational knowledge for a clearly defined purpose.

Retrieval can locate relevant policies, records, documents, transactions and previous interactions. LLM intelligence can then interpret that evidence, connect related information, explain its meaning and formulate an appropriate response.

The relationship can be expressed simply:

Knowledge provides the evidence. The LLM provides the language intelligence and reasoning required to make that evidence useful.

The LLM should not replace the knowledge system, business rules, calculations or access controls. Its role is to work within those foundations and convert trusted business context into meaningful assistance.

The Flow

The intelligence flow

A single chain from request to delivery, with governed knowledge and response boundaries feeding in at the two points where they matter.

  1. 01 Business request and purposeWhat the interaction is meant to achieve.
  2. 02 Identity and interaction contextWho is asking, through which channel.
  3. 03 Secured knowledge retrievalDraws on persistent organisational knowledge, within the actor's authorised scope.
  4. 04 Authorised evidence contextThe assembled evidence this interaction is permitted to use.
  5. 05 Purpose-aware LLM intelligenceReasons over that evidence, under supplied instructions and response boundaries.
  6. 06 Grounded answer, insight or guidanceThe result, traceable to the evidence behind it.
  7. 07 Validation, evidence and deliveryChecked against grounding and boundaries, then returned through the channel.
Knowledge feeds retrieval; instructions and boundaries feed reasoning. Neither reaches the model unfiltered.

Boundaries this flow maintains

  • Identity and access are established before sensitive knowledge reaches the LLM.
  • Retrieval determines which organisational evidence is relevant and authorised.
  • The LLM operates only within the context supplied for the interaction.
  • Business rules and source systems remain authoritative.
  • The resulting answer or insight is checked against its evidence and response boundaries.
  • The outcome is delivered through the appropriate communication channel.

From information retrieval to business understanding

A conventional search system primarily helps a person find information. It may return a document, record, page or list of matching results.

LLM intelligence can extend this experience by helping the person understand what the retrieved information means within a particular business situation.

For example, a knowledge system may retrieve:

  • A company leave policy
  • An employee's current leave balance
  • Applicable public holidays
  • Previously approved leave
  • The employee's department-specific rules

The LLM can use this authorised evidence to explain whether the employee may apply for a particular period, identify relevant conditions and communicate the answer in clear language.

The knowledge system provides the facts. The LLM connects and communicates them for the employee's specific purpose.

The objective is not merely to retrieve knowledge, but to make authorised knowledge understandable and useful within the context of a real business need.

The Reasoning Context

What the model is given to work with

The LLM should not receive an isolated question and be expected to determine everything independently. It should operate within a controlled reasoning context containing the information required for the purpose.

Context elementWhat it provides
Business purposeThe outcome the interaction is intended to support
Actor contextThe relevant role, relationship and verified identity of the person
Interaction contextThe channel, conversation, task and current situation
Authorised evidenceRetrieved knowledge the actor is permitted to use
Business instructionsRelevant policies, terminology, response rules and limitations
Output requirementsThe required format, level of detail, sources and next step

This controlled context allows the same LLM to support many purposes without behaving as an unrestricted general-purpose assistant.

Only the minimum relevant identity and business information should be included. Verification and authorisation remain responsibilities of the surrounding system — not decisions left to the model.

The capabilities of LLM intelligence

LLM capabilities should be selected according to the purpose of the interaction. Not every use case requires complex reasoning.

01Understanding requests

People rarely communicate using the exact terminology, classifications or field names maintained by a business system. LLM intelligence can help:

  • Interpret natural-language questions
  • Recognise the likely intent
  • Identify relevant business entities
  • Understand conversational references
  • Detect ambiguity
  • Reformulate the request into a clearer knowledge requirement
  • Ask for clarification when necessary

This capability helps bridge the difference between how people naturally communicate and how business information is organised. The LLM may assist in interpreting what knowledge is needed, but access policies still determine what can be retrieved.

02Explaining and transforming knowledge

Organisational knowledge may be technically correct but difficult for its intended audience to understand. The LLM can:

  • Explain complex policies in simpler language
  • Summarise lengthy documents
  • Convert technical information into business language
  • Translate content into another language
  • Reformat information for a particular channel
  • Adapt the level of detail to the user
  • Present procedural knowledge as guided steps

The underlying meaning must remain faithful to the source. Simplification should not become alteration.

03Connecting and synthesising information

Many business questions cannot be answered from a single record or document. The LLM can combine authorised evidence from multiple sources to:

  • Bring related facts together
  • Reconcile information from documents and operational systems
  • Identify common themes
  • Compare policies, products, records or situations
  • Summarise a customer, project or transaction context
  • Produce a unified explanation from distributed evidence

This is one of the most important advances beyond conventional search. The system can move from returning separate pieces of information to presenting a coherent business understanding.

04Contextual reasoning

Reasoning becomes valuable when the answer is not explicitly written in one source but can be responsibly developed from the available evidence. The LLM may help:

  • Identify relationships between facts
  • Recognise conditions that apply to a situation
  • Compare the present state with an expected state
  • Identify possible causes or implications
  • Evaluate stated alternatives
  • Detect missing or conflicting information
  • Develop a provisional conclusion supported by evidence
  • Explain why a particular conclusion may be relevant

Such conclusions must remain within the available evidence. When several interpretations are possible, the system should present the uncertainty rather than converting an assumption into a fact.

05Decision support

For authorised purposes, the LLM can help a person evaluate a situation without becoming the final decision authority. It may:

  • Present available options
  • Compare advantages, limitations and risks
  • Highlight relevant policies or previous cases
  • Identify information missing from the decision
  • Suggest possible next steps
  • Produce a recommendation with supporting evidence
  • Indicate when specialist or managerial review is required

The responsibility for the final decision should remain clear, particularly for financial, legal, employment, safety-related or regulated matters.

06Grounded content generation

The LLM can generate useful business material using authorised organisational context — customer responses, internal summaries, meeting briefs, project updates, draft proposals, policy explanations, case histories, knowledge articles and management observations.

07Adaptive communication

The same underlying knowledge may need to be communicated differently depending on the actor and channel. The LLM can adapt language, tone, technical depth, length, structure, terminology, response format and the recommended next step.

A customer may require a concise explanation, an employee may require procedural guidance, and a manager may require a detailed analytical summary. The source knowledge may be related, but the communication purpose is different.

Levels

The use of LLM capabilities can progress through controlled levels. Progressing upward increases potential value, but also increases the need for stronger evidence, evaluation and human oversight.

Structured guidanceClarificationHuman handover

An organisation does not need to begin at the highest level. A reliable grounded-answer capability may create more business value than an advanced reasoning system operating over incomplete or poorly governed knowledge.

Distinguishing fact, derivation and recommendation

A trustworthy system should not present every output as if it carries the same authority.

Output categoryMeaningExample
Sourced fact Directly supported by an authorised source “The contract expires on 30 September.”
System-derived result Calculated or determined by an authoritative business system “The available stock balance is 42 units.”
LLM-derived insight A contextual interpretation developed from available evidence “The delay appears primarily associated with pending approval.”
Recommendation A suggested course of action based on the available context “Consider completing the approval before rescheduling delivery.”

This separation is particularly important when the LLM identifies patterns, possible causes or recommended actions. The system should communicate whether an output is:

  • Directly stated in a source
  • Calculated by an authoritative system
  • Inferred from the available evidence
  • Recommended as a possible next step
  • Subject to human verification

Fluent language must not blur these distinctions.

Reasoning and deterministic business logic

LLM reasoning should complement — not replace — deterministic business logic. Exact calculations and validations should normally remain with the appropriate systems. These include tax calculations, payroll processing, inventory balances, financial totals, permission checks, credit-limit validations, statutory rules, workflow conditions and transaction posting.

The LLM may explain the result, compare it with other information or identify its possible business implications. However, authoritative calculations should come from the relevant business application, approved rule engine or verified analytical process.

Let business systems establish what is exact. Let the LLM help people understand what it means.

The Cycle

The governed reasoning cycle

Each interaction should follow a controlled cycle.

  1. 01Establish the business purpose and interaction context.
  2. 02Verify the actor and determine the authorised knowledge scope.
  3. 03Interpret the request and identify the required knowledge.
  4. 04Retrieve relevant evidence from approved sources.
  5. 05Assemble the evidence, instructions and response boundaries.
  6. 06Apply the LLM capabilities appropriate to the purpose.
  7. 07Validate grounding, restrictions and factual consistency.
  8. 08Communicate the result with sources, limitations and an appropriate next step.
  9. 09Record feedback and operational evidence for improvement.

This process does not require the system to expose or preserve the model's private internal chain of thought. Accountability comes from recording the request, supplied evidence, policies, generated outcome, validation results and business consequences.

Handling insufficient or conflicting knowledge

An AI-ready system must recognise that an answer is not always available. The retrieved evidence may be incomplete, outdated, contradictory or insufficient for the requested purpose. In such cases, the LLM should be able to:

  • State what information is available
  • Identify what is missing
  • Highlight conflicting sources
  • Ask a focused clarification question
  • Restrict the conclusion
  • Recommend verification
  • Refer the matter to an authorised person

Applying the model across business purposes

The same foundation can support highly diverse applications.

Customer assistance

A verified customer asks about an order. The system retrieves only that customer's authorised order and delivery information. The LLM explains the present status, relevant conditions and available next steps.

Employee knowledge assistance

An employee asks about leave eligibility. The system combines the applicable policy with the employee's authorised leave information. The LLM provides a personalised explanation without exposing another employee's data.

Operational analysis

A project manager asks why a project margin has declined. Authorised project costs, budgets, approved changes and progress information are retrieved from the relevant systems. The LLM connects the evidence and presents possible contributing factors, clearly distinguishing system-calculated values from inferred observations.

Product and service discovery

A website visitor describes a business requirement without knowing the organisation's product terminology. The LLM interprets the requirement, retrieves public product knowledge and explains which available services may be relevant.

These examples use different knowledge, identities and reasoning capabilities, but they operate on the same universal foundation.

The Governing Principle

The LLM should use its capabilities to understand, connect, explain and reason over authorised business evidence for a defined purpose — while organisational knowledge, access policies, business rules and authoritative calculations remain under the control of the surrounding business system.

This is how an organisation moves beyond adding conversational AI to its software. It creates an environment in which LLM capabilities are purposefully applied to governed business knowledge — producing assistance that is useful, contextual, secure and accountable.

Section 04

Designing purpose-specific AI use cases

Turning LLM capabilities into measurable business value

The previous sections established the foundation of an AI-ready business system and explained how LLM intelligence can work over governed organisational knowledge. The next challenge is deciding where and how that intelligence should be applied.

This is where many AI initiatives become unfocused. Organisations may begin with a broad ambition such as:

  • Create an AI assistant
  • Add intelligence to the ERP
  • Build a customer-service chatbot
  • Use AI for management decisions
  • Introduce an AI agent

These describe technologies or interfaces. They do not yet define a business use case.

A purpose-specific AI use case must answer a more precise question:

For which actor, in which business situation, using what authorised knowledge, should the LLM provide what form of intelligence — and how will the organisation determine whether it produced value?

The unit of design is therefore not the LLM, the prompt or the communication channel.

The unit of design is a governed business interaction with a defined purpose, evidence boundary, expected outcome and measure of success.

From general AI capability to a defined business purpose

LLMs provide broadly applicable capabilities. They can understand language, identify intent, summarise information, connect evidence, explain situations, compare alternatives, generate content and support contextual reasoning. However, these capabilities create value only when they are directed towards a particular business requirement.

LLM capabilitySummarise information

Purpose-specific use casePrepare a concise project-status brief for an authorised project manager using the latest approved progress, cost, procurement and risk information

LLM capabilityAnalyse information

Purpose-specific use caseHelp a finance manager understand the principal factors contributing to a project-margin variance without recalculating or changing the accounting records

Broad ambitionAnswer customer questions

Purpose-specific use caseExplain the current delivery status of a verified customer's order using authorised order, dispatch and logistics information

The distinction matters because the purpose determines:

  • Who may use the capability
  • Which knowledge may be retrieved
  • What business context is required
  • Which LLM capabilities are appropriate
  • Which deterministic systems remain authoritative
  • What the response may contain
  • What the system must not do
  • When human intervention is required
  • How success and failure will be measured

Purpose

Three levels of purpose

A well-designed use case distinguishes three related but different levels of purpose. These levels should not be merged.

LevelGoverning questionExample
Business outcome Why should the organisation provide this capability? Reduce the time required to investigate project-margin variations
Interaction outcome What should the actor receive or understand? A grounded explanation of the principal contributing factors
LLM task How should LLM intelligence contribute? Synthesise authorised cost, budget, progress and change information into a coherent explanation

The business outcome justifies the investment. The interaction outcome defines the value delivered to the user. The LLM task defines the limited role intelligence will perform within the surrounding business system.

A use case may fail even when the LLM task performs well. For example, an excellent summary has limited value if it does not help the intended user complete a task, make a better decision or reduce operational effort.

The Model

The purpose-specific use-case model

A complete use case connects purpose, authority, evidence, intelligence, outcome and accountability — and closes the loop back to the purpose it started from.

  1. 01 Business purpose and expected outcomeBegin with a legitimate business purpose.
  2. 02 Actor, authority, trigger and contextIdentify who needs assistance, and in what situation.
  3. 03 Authorised knowledge and evidenceDetermine the knowledge that may be accessed.
  4. 04 Selected LLM capabilitiesSelect only the capabilities the purpose needs.
  5. 05 Bounded response or assistanceDefine the permitted response, recommendation or assistance.
  6. 06 Validation, escalation and measurementValidate the result and measure its business effect — which feeds back to the purpose.
Measurement returns as evidence to the purpose. A use case that cannot close this loop cannot be shown to have produced value.

The controlled progression

  • Begin with a legitimate business purpose.
  • Identify the actor and the situation in which assistance is required.
  • Determine the knowledge that may be accessed.
  • Select only the LLM capabilities needed for the purpose.
  • Define the permitted response, recommendation or assistance.
  • Validate the result and measure its business effect.

The channel through which the interaction occurs is part of its context. It should not redefine the underlying purpose, knowledge or intelligence independently. The same use case may be available through an ERP interface, mobile application or internal messaging channel while continuing to use the same governed knowledge and response boundaries.

Designing the use case from the outcome backwards

A reliable AI use case should be designed from the intended business outcome backwards — not from an available model or feature forwards.

01Define the business situation

The design should begin with a real business situation in which a person currently needs to find, understand, combine or interpret information. The organisation should establish:

  • What situation causes the need
  • What the person is trying to accomplish
  • How the task is currently performed
  • Where delay, complexity or inconsistency occurs
  • What better outcome is expected
  • Who owns the business outcome
  • Why LLM intelligence may be useful

A strong purpose statement describes the business need without exaggerating the role of AI.

A weak statementProvide AI-powered project analysis.

A stronger statementHelp authorised project managers identify and understand the principal factors contributing to a project-margin variation by synthesising current system-calculated financial values with approved project, procurement, progress and change records.

The stronger statement identifies the actor, situation, evidence and intended value. It also preserves the authority of the financial system.

02Identify the actor, subject and authority

The person interacting with the capability is not always the only person affected by it. The design should distinguish:

  • Actor: the person or system initiating the interaction
  • Subject: the customer, employee, project, transaction or other entity being discussed
  • Beneficiary: the person or organisation receiving the intended value
  • Business owner: the person accountable for the use case
  • Decision authority: the person authorised to accept, reject or act on the result

For each actor, the use case should define:

  • Required identity level
  • Organisation or tenant
  • Role and business relationship
  • Record-level or entity-level access
  • Delegated authority
  • Consent requirements
  • Channel restrictions
  • Additional verification requirements
  • Information that must remain inaccessible

03Define the trigger and interaction context

A purpose-specific use case occurs within a recognisable situation. It may begin through a direct question, a request for explanation, a selected business record, a workflow stage, a detected exception, a scheduled review, a system event, or the continuation of an authorised conversation.

The required context may include:

  • The active customer, employee, project or transaction
  • The relevant date or reporting period
  • The current workflow state
  • The communication channel
  • Previous messages in the same authorised interaction
  • The actor's role and task
  • Applicable organisational unit or location
  • Language and response preferences

Context should be explicit wherever possible. The system should not force the LLM to infer a project, customer or reporting period when these values can be obtained directly from the application.

Business systems should provide context they already know instead of asking the LLM to guess it from conversation.

Step 04

Establish the knowledge and evidence contract

Every use case requires a defined knowledge scope. This should not be described merely as "access to company data." The design must specify which sources are required, permitted or prohibited.

Required knowledge

Information without which the use case cannot reliably produce its intended outcome.

Supporting knowledge

Additional information that may improve explanation or context but is not required for every interaction.

Restricted knowledge

Information that may be used only for certain identities, roles, entities or verified conditions.

Prohibited knowledge

Information the use case must never retrieve or expose, even if it exists within the broader organisation.

The knowledge contract should define:

Knowledge propertyDesign question
SourceWhich system, document or repository owns the information?
AuthorityIs the source approved, provisional, externally obtained or user supplied?
ScopeWhich records, entities and periods may be considered?
ClassificationIs the information public, internal, confidential or restricted?
FreshnessHow current must the information be?
ValidityIs the record approved, submitted, active, expired or superseded?
PrecedenceWhich source takes priority if information conflicts?
ProvenanceCan the result be traced to its origin?
CompletenessWhat evidence must be present before a conclusion is allowed?

This forms an evidence contract between the use case and the knowledge foundation. The contract prevents retrieval from becoming an uncontrolled search across everything the organisation has stored. It also supports data minimisation: only the knowledge necessary for the particular purpose should be retrieved.

05Allocate responsibilities correctly

Purpose-specific design must clearly separate what the LLM does from what the surrounding systems do.

ComponentPrimary responsibilityShould not be expected to
Business applicationsMaintain authoritative records, calculations and workflow statesDepend on the LLM for exact transactional truth
Knowledge systemPreserve content, context, classification and provenanceGrant access merely because information is retrievable
Identity and policy controlsVerify the actor and establish the permitted scopeDelegate security decisions to model instructions
Retrieval capabilityLocate and assemble relevant authorised evidenceSupply all available information indiscriminately
LLM intelligenceUnderstand, synthesise, explain, infer carefully and communicateBecome the source of organisational truth or permission
Validation controlsCheck grounding, constraints, required fields and output boundariesRely only on the model's own claim of confidence
Human authorityHandle judgement, approval, exceptions and accountabilityBe silently replaced in high-impact decisions
Transaction or workflow serviceExecute independently authorised and validated actionsTreat generated language as automatic authority to act

This responsibility model is essential. A prompt cannot replace access control. LLM reasoning cannot replace an accounting calculation. A fluent recommendation cannot replace an authorised approval. Retrieval relevance cannot establish whether the information is legally or operationally permitted.

06Select the necessary LLM capabilities

The design should select the minimum set of LLM capabilities needed to achieve the purpose. These may include natural-language understanding, intent recognition, entity identification, ambiguity detection, explanation, summarisation, information transformation, multi-source synthesis, contextual reasoning, comparison of alternatives, decision support, grounded drafting, adaptive communication, and clarification and guided assistance.

Not every use case requires analytical reasoning or decision support. If a conventional query can reliably return an exact balance, the LLM may only be needed to explain that balance. If a deterministic rule can establish eligibility, the business system should evaluate the rule and the LLM may communicate the result.

LLM intelligence is most useful where the task involves language, distributed evidence, ambiguity, contextual interpretation or communication adapted to a particular audience.

Use the LLM where intelligence adds meaning — not where deterministic software already provides certainty.

07Define the output contract

The expected output must be designed as carefully as the input. The use case should specify:

  • The type of response required
  • The permitted level of interpretation
  • The required source references
  • The distinction between facts and inferences
  • The expected format and level of detail
  • Mandatory warnings or limitations
  • Conditions requiring clarification
  • Permitted recommendations
  • Prohibited conclusions
  • Whether human review is required
  • Whether any subsequent action is allowed

A useful output structure may include:

  1. The direct answer or conclusion
  2. Supporting facts from authorised sources
  3. System-calculated results, clearly identified
  4. LLM-derived observations, clearly distinguished
  5. Missing or conflicting information
  6. Suggested next steps
  7. Required human review or escalation

The use case should preserve the distinction established in the previous section — sourced fact, system-derived result, LLM-derived insight and recommendation. These categories should not be blended into one apparently authoritative statement.

Any quality or confidence indicator should be based on observable factors such as evidence coverage, source freshness, conflicts, validation results and retrieval quality. It should not depend solely on the model's self-assessed confidence.

08Define uncertainty, refusal and escalation

A trustworthy use case must be designed for situations in which the requested outcome cannot safely be produced. These conditions may include:

  • The actor cannot be sufficiently verified
  • The requested information is outside the actor's access scope
  • Required evidence is missing
  • Sources contain conflicting information
  • Information is outdated
  • The question is ambiguous
  • The requested conclusion is not supported
  • The matter requires professional or managerial judgement
  • The potential impact exceeds the permitted risk boundary
  • The interaction falls outside the stated purpose

The response behaviour should be defined in advance. Depending on the situation, the system may ask a focused clarification question, explain which information is unavailable, present conflicting evidence without resolving it, restrict the conclusion, decline the request, request additional verification, recommend review by an authorised person, transfer the interaction with its relevant context, or record an exception for investigation.

Step 09

Define success before implementation

A use case should not be approved merely because it produces an impressive demonstration. Success must be defined across several dimensions.

DimensionPossible measures
Business valueTime saved, resolution time, cost to serve, decision cycle, task completion or reduced rework
Knowledge qualitySource coverage, freshness, completeness and conflict rate
Retrieval qualityRelevance, evidence coverage and correct enforcement of scope
Response qualityFactual grounding, completeness, clarity and instruction adherence
SecurityAuthorisation accuracy, data minimisation and absence of unauthorised disclosure
Human effectivenessUser acceptance, correction rate, escalation quality and decision usefulness
Operational reliabilityResponse availability, latency, traceability and exception handling
Outcome qualityWhether the intended business result was actually improved

Evaluation should include representative situations rather than only ideal questions. A use-case evaluation set should contain:

  • Common requests
  • Differently worded requests with the same intent
  • Ambiguous requests
  • Missing-information cases
  • Conflicting-source cases
  • Outdated-information cases
  • Unauthorised requests
  • Cross-customer or cross-project access attempts
  • Requests outside the use-case purpose
  • High-impact or exception scenarios
  • Cases requiring human escalation

The purpose is not to prove that the LLM can always answer. It is to confirm that the complete system responds appropriately across answerable, uncertain, restricted and exceptional situations.

The Contract

The purpose-specific AI use-case contract

The design can be consolidated into a reusable contract.

For
a defined actor,
when
a recognised business situation occurs,
the system will use
specifically authorised knowledge and context,
apply
selected LLM capabilities,
to provide
a bounded and evidence-grounded outcome,
while preserving
defined security, authority and escalation conditions,
and success will be measured by
agreed business, quality and trust indicators.

This contract prevents an AI use case from remaining an attractive but technically ambiguous idea.

The Canvas

Purpose-specific use-case canvas

The following canvas can be used to design and review each proposed implementation.

Design elementRequired definition
Use-case nameA precise description of the business assistance being provided
Business problemThe existing difficulty, delay, inconsistency or opportunity
Intended outcomeThe measurable improvement expected
Business ownerThe person accountable for the outcome and continued operation
Actor and beneficiaryWho interacts and who receives the value
SubjectThe customer, employee, project, product, transaction or case involved
TriggerThe question, event, exception or workflow state that starts the interaction
Identity requirementHow the actor must be identified or verified
Authority boundaryWhat information and decisions fall within the actor's scope
Interaction contextChannel, task, entity, period, location and conversation context
Required knowledgeAuthoritative evidence necessary for the outcome
Optional knowledgeSupporting evidence that may improve the response
Prohibited knowledgeInformation that must never be retrieved for the use case
Deterministic logicCalculations, validations and rules retained by business systems
LLM capabilitiesUnderstanding, synthesis, explanation, reasoning, drafting or guidance
Output contractFormat, evidence, distinctions, limitations and permitted next steps
Failure behaviourClarification, refusal, restriction, fallback or escalation
Audit evidenceSources, policies, inputs, validations and outcome records retained
Evaluation setNormal, ambiguous, conflicting, unauthorised and exceptional cases
Success measuresBusiness value, grounding, security, quality and user-effectiveness targets

The completed canvas becomes the shared design reference for business owners, solution architects, knowledge owners, security teams, developers and evaluators.

Worked Example

Explaining a project-margin variation

Consider a project manager who needs to understand why the expected margin of an active project has declined.

Business purpose

Reduce the effort required to investigate margin variations and help the project manager identify matters requiring attention.

Actor and authority

The actor is a verified project manager. Access is restricted to projects assigned to that manager and to financial information permitted by the person's role.

Trigger

  • The project manager asks for an explanation
  • A project is selected in the ERP
  • A system-calculated margin crosses an organisational threshold
  • A scheduled project review is initiated

Authoritative knowledge

  • Approved project budget
  • Current system-calculated revenue and cost values
  • Purchase invoices and committed purchase orders
  • Approved variation orders
  • Material issues and returns
  • Timesheets or labour costs
  • Subcontractor costs
  • Progress and billing information
  • Approved project notes
  • Relevant reporting periods and accounting status

Draft, cancelled and unapproved records must be treated according to clearly defined rules.

Deterministic responsibilities

The ERP or financial system remains responsible for:

  • Ledger values
  • Cost totals
  • Revenue recognition
  • Tax treatment
  • Currency conversion
  • Margin calculations
  • Document status
  • Accounting periods

The LLM must not recreate these calculations from fragments of retrieved text.

LLM responsibilities

  • Understand the manager's question and requested period
  • Bring the relevant system results and supporting records together
  • Compare actual and expected cost categories
  • Connect approved project events with significant variations
  • Identify missing or conflicting information
  • Explain confirmed contributors
  • Present possible contributors as inferences
  • Suggest areas requiring investigation

Prohibited behaviour

  • Change financial records
  • Treat unapproved costs as confirmed liabilities
  • Access unrelated projects
  • Invent a reason when evidence is incomplete
  • Approve a variation or accounting adjustment
  • Present an inferred cause as an established fact

Expected output

  1. The current system-calculated margin and relevant comparison
  2. Confirmed cost or revenue variations
  3. Evidence associated with each confirmed factor
  4. Possible contributing factors, separately labelled
  5. Missing, late or conflicting information
  6. Recommended review actions
  7. Any required finance or management escalation

Success measures

  • Time required to complete the investigation
  • Correct identification of material contributing factors
  • Accuracy of source references
  • Rate of unsupported claims
  • Appropriate handling of incomplete evidence
  • Prevention of cross-project information exposure
  • Acceptance or correction by authorised project and finance personnel

This use case does not ask the LLM to become the accounting system or project authority. It uses LLM intelligence to make authorised operational and financial evidence easier to understand.

Qualification

Qualifying a proposed AI use case

Before implementation, every proposed use case should pass several tests.

01

The purpose test

Is there a clear business situation, intended user and measurable outcome?

02

The intelligence test

Does the task genuinely benefit from language understanding, synthesis, contextual interpretation or adaptive communication? If deterministic reporting or conventional automation can solve the requirement completely, an LLM may not be necessary.

03

The knowledge test

Does reliable, current and sufficiently classified knowledge exist? If not, knowledge preparation should precede implementation.

04

The authority test

Can the organisation define who may access the knowledge, receive the outcome and act upon it?

05

The evidence test

Can important statements, calculations and conclusions be traced to authoritative sources?

06

The boundary test

Can the organisation state what the LLM may and may not conclude, recommend or initiate?

07

The failure test

Can the system respond safely when information is insufficient, conflicting, unauthorised or outside the purpose?

08

The measurement test

Can the organisation determine whether the use case improves a real business outcome?

A proposed capability that cannot pass these tests is not yet a deployable use case. It may instead reveal required work in knowledge preparation, access design, process definition or business ownership.

Portfolio

Prioritising the use-case portfolio

Not every valuable idea should be implemented immediately. Use cases should be evaluated according to:

  • Potential business value
  • Frequency of the business need
  • Knowledge readiness
  • Clarity of access rules
  • Verifiability of the outcome
  • Complexity of integration
  • Consequence of an incorrect result
  • Requirement for human judgement
  • Availability of an accountable owner
ClassificationAppropriate direction
High value, strong knowledge readiness and verifiable outcomeSuitable for controlled implementation or pilot
High value but weak knowledge or access readinessPrepare the foundation before implementation
Mostly deterministic with little need for language intelligenceUse conventional reporting, rules or automation
High impact but difficult to verify or governDefer, narrow or introduce mandatory human review
Unclear purpose or no accountable ownerDo not proceed until the business case is defined

A modest use case with reliable evidence and measurable value is usually a stronger starting point than an ambitious assistant expected to understand the entire organisation.

Failure Patterns

Common design failures

Purpose-specific design helps avoid several recurring failures.

  • Selecting an LLM before defining the business purpose
  • Building a general assistant and searching for uses afterwards
  • Treating all organisational information as one unrestricted knowledge source
  • Attempting to enforce security only through prompts
  • Expecting LLM reasoning to compensate for incomplete or unreliable knowledge
  • Allowing the model to reproduce calculations owned by authoritative systems
  • Failing to distinguish fact, inference and recommendation
  • Designing only the successful response and ignoring uncertainty
  • Measuring fluency instead of business outcomes and factual grounding
  • Creating separate knowledge behaviour for every communication channel
  • Allowing generated content to become organisational truth without validation
  • Introducing actions without independent authority, approval and audit controls

These are not merely technical defects. They arise when the business purpose, responsibilities and operational boundaries have not been sufficiently designed.

From use-case design to implementation

A completed purpose-specific design should produce more than a written description. It should provide the implementation team with:

  • A business and interaction outcome
  • A defined actor and authority model
  • A knowledge and evidence contract
  • Retrieval scope and filtering requirements
  • Required business and interaction context
  • A precise allocation of system and LLM responsibilities
  • Purpose-specific instructions
  • An output contract
  • Validation and escalation rules
  • An evaluation dataset
  • Success thresholds
  • Operational ownership and review responsibilities

Only after these elements are defined should the organisation select models, design prompts, configure retrieval, connect channels or build the user experience.

The implementation architecture should follow the use case — not force the use case to follow the capabilities of a particular model or platform.

The Governing Principle

An AI use case is complete only when it defines why intelligence is required, who it serves, what authorised evidence it may use, how the LLM should contribute, where its authority ends, how uncertainty will be handled and how business value will be proven.

This is how the universal foundation and LLM capabilities are transformed into reliable business applications. It moves the organisation from the general ambition to "use AI" towards a portfolio of controlled, measurable and accountable intelligence capabilities — each designed for a real purpose.
