'''AI use case''' ('''artificial intelligence use case''') is a defined application of [[Artificial Intelligence (AI)|artificial intelligence]] to a particular business, operational or public-service need. It describes the work to be performed, the people and processes involved, what information an AI system uses, the output it is expected to produce, how that output influences a decision or action, and the outcome the organization seeks to achieve. The term may refer to an intended use under consideration, an experiment, a deployed application or a use that has been retired. The United States Government Accountability Office (GAO) describes AI use cases as applications of AI for particular business needs.<ref name="gao2026">United States Government Accountability Office (GAO) (2026), ''Artificial Intelligence: IRS Actions Needed to Address Skills Gaps, Information Quality, and Strategic Management'', GAO-26-107522, 24 March 2026. [https://www.gao.gov/products/gao-26-107522 GAO]. Accessed 9 November 2026.</ref>

For example, an IT department may propose an AI use case in which service requests are classified using information supplied by employees, with uncertain cases referred to a service-desk analyst. The task is ''classifying requests''; the AI output is a suggested category or routing destination; the operational decision is where the request goes; and possible outcomes include fewer routing errors and less rework. Whether either benefit actually occurs must be measured. Naming a language model or purchasing an AI-enabled service-desk product, by itself, does not describe this use case.

An AI use case connects a capability to its context of use. A [[Machine Learning|machine-learning]] model, [[Generative AI|generative AI]] application or [[AI Agent|AI agent]] may enable the work, but the use case defines what that technology is being used to accomplish and under what conditions. The related term [[Use Case|use case]] also has a formal meaning in software requirements engineering; an AI use case may be described using such methods, but an organizational AI-use inventory is not necessarily a set of UML use-case specifications. This entry concerns the ''purpose, boundaries, evidence and management of a particular use of AI'', rather than a catalog of unrelated AI examples.

== Meaning and scope ==

The word ''use'' is central. An AI capability becomes a meaningful use case when its proposed role in a real activity can be described and assessed. ''Using AI for finance'' is a broad opportunity area. ''Classifying incoming supplier invoices and flagging uncertain matches for an accounts-payable reviewer'' is a more specific use case. The second statement identifies work, an AI contribution, a reviewer and a decision boundary. It can be tested against a non-AI approach.

An AI use case does not need to be automated from end to end. In some contexts the AI system identifies anomalies, generates a draft or recommends an action while a person remains accountable for the decision. In others the system may carry out a limited, authorized action. Nor does an AI use case necessarily involve generative AI; prediction, classification, optimization, perception and planning can all serve specific uses. The context, output and consequences—not a fashionable model label—determine the case's requirements.<ref name="nistmap">National Institute of Standards and Technology (NIST) (2023), ''Artificial Intelligence Risk Management Framework (AI RMF 1.0) Playbook: Map'', especially MAP 1.1 concerning intended purpose, users, deployment context and impacts. [https://airc.nist.gov/airmf-resources/playbook/map/ NIST AI RMF Playbook]. Accessed 9 November 2026. NIST indicates that AI RMF 1.0 is undergoing revision; this citation refers specifically to the 1.0 material.</ref>

A useful way to recognize an AI use case is to ask: ''What work changes because an AI output is introduced, who is responsible for using that output, and what difference would count as a successful result?'' If these questions cannot yet be answered, the organization may have a technology idea or an area for exploration rather than a sufficiently specified use case.

== How an AI use case is described ==

A complete description makes the use sufficiently specific to assess without prematurely prescribing a particular vendor, model or architecture. The level of detail should fit the stakes of the decision. A low-risk internal drafting assistant and a system that influences eligibility for a public benefit will require different evidence and controls. NIST's AI RMF emphasizes documenting purpose, intended users, setting, benefits, potential harms and evaluation needs as part of understanding an AI system's context.<ref name="nistmap" />

The elements form a connected account of ''why this use exists, what the AI does, what changes afterward, and how anyone would know whether the change helped''. They are descriptive fields, not a mandatory universal template or a substitute for relevant local requirements.

== From AI output to operational outcome ==

An AI use case is usually embedded in a larger workflow. The model or reasoning component processes information, but the business result depends on what people and connected software do with the output. The distinction can be represented as a sequence:

# '''Trigger and context:''' a service request, transaction, image, document, sensor event or user question creates a need for action.
# '''Authorized input:''' relevant data or represented knowledge are made available under applicable access and quality requirements.
# '''AI operation:''' a model or reasoning method classifies, predicts, extracts, generates, recommends or plans.
# '''Interpretation and control:''' a person or application tests confidence, applies policy, checks permissions or requests clarification.
# '''Decision or action:''' the result informs a human decision or initiates an allowed workflow operation.
# '''Feedback and assessment:''' the organization observes errors, benefits, adverse effects and changes in operating conditions.

These steps may be combined, repeated or partly manual. An [[Agentic AI|agentic AI]] system could involve multiple actions and tools; a predictive model could simply display a probability to an analyst. The use-case boundary should make clear which operations fall within its authorized scope and which belong to adjacent systems. An otherwise accurate AI output may have little value if it reaches the wrong person, arrives too late or cannot be incorporated into a working process.

Consider an invoice-processing case: a model extracts supplier name and amount from a scanned document. If an operator must still reconstruct every field manually, the model's extraction accuracy has not established a useful process improvement. Conversely, a modest improvement in extraction quality could be valuable if it reliably reduces exceptions and downstream rework without adding unacceptable payment errors. The relevant result belongs to the ''process in use'', rather than to the model considered alone.

== Choosing the right boundary for a use case ==

Use cases should be separated when different purposes, affected populations, decision rights or material risks require independent assessment. They may be grouped when they constitute one coherent operating objective and can be evaluated together. There is no fixed requirement that one model equals one use case, or that one use case uses only one model.

Public-sector inventories illustrate why this boundary matters. GAO found that the US Internal Revenue Service had sometimes removed entries wrongly labeled as AI or split entries that covered several individual uses; its inventory also omitted some uses. Therefore, a reported count is shaped by definition, discovery, granularity and reporting rules. It should not automatically be read as a count of production systems or verified benefits.<ref name="gao2026" />

== Main forms of AI use cases ==

AI use cases can be grouped by the function performed, the organizational process affected, the people served, the degree of authorized autonomy or the risk of the outcome. These are overlapping classifications, not mutually exclusive types. One use may combine several AI methods, and the same method may support many unrelated business tasks. Google Cloud and IBM describe multiple technical and business application families, though their catalogs also reflect vendor perspectives.<ref name="googleapps">Google Cloud, ''Applications of artificial intelligence (AI)'', overview of NLP, computer vision, document processing, recommendation and other application categories.

A second classification uses affected business processes: customer service, finance, maintenance, procurement, [[IT Service Management (ITSM)|IT service management]], [[Cybersecurity|cybersecurity]], software engineering, healthcare and other domains. Sector labels help discovery, but they are insufficient descriptions of particular uses because they omit the actual task and decision context. Detailed catalogs of examples, if separately published, should not be confused with the definition of an AI use case.

== Examples of AI use cases and their evidence ==

An ''illustrative use case'' describes a possible application. An ''inventoried use case'' records a declared use or planned use under the reporting rules of an organization. A ''documented outcome'' requires evidence that the use changed a specified result. These evidence categories should not be collapsed into a single claim of success.

|}

None of these examples establishes that the same technology will be safe, economical or effective in another context. Source type matters: an organizational inventory, vendor description, laboratory benchmark and controlled workplace study answer different questions. An AI use case with compelling technical results may still fail to improve service quality or may create costs and harms that offset the benefit.

== Illustrative AI use case: IT incident triage ==

The following scenario is hypothetical. It shows how one organizational use can be defined without presenting an unverified deployment or inventing measured savings.

A technology organization receives incident reports describing application errors, slow systems and service interruptions. Analysts currently read every report, choose an incident category, determine urgency and route it to the appropriate response group. Frequent reassignment slows work, but the organization does not yet know how much of the delay is caused by initial classification. It proposes using AI to assist with ''initial incident classification and routing'', retaining human authority over declared major incidents and production-change decisions.

=== Defining the use ===

* '''Purpose:''' reduce avoidable ticket transfers while preserving correct urgency and escalation.
* '''Inputs:''' the incident description, permitted configuration or service data, historical resolved tickets and a current service taxonomy.
* '''AI function:''' classify likely incident type and suggest a receiving support group; provide an uncertainty indicator or route ambiguous cases for manual review.
* '''Output:''' a suggested category and group displayed in the [[IT Service Management (ITSM)|ITSM]] application.
* '''Decision right:''' routine routing may be allowed under defined rules; potential [[Major Incident|major incidents]] and sensitive records require human judgment and existing controls.
* '''Boundary:''' the AI does not authorize a [[Change Request|change request]], alter security permissions or execute a production fix.
* '''Baseline and measures:''' compare initial-routing accuracy, reassignment, incident-resolution time, analyst effort, incorrect criticality, and user-impact measures with representative prior or concurrent work.

=== What evaluation would establish ===

The case should be tested on real incident categories, including rare but consequential events, and reviewed for data leakage or uneven performance across business units. If routing accuracy improves but escalation of critical incidents becomes slower, the use cannot be described as a straightforward success. If analyst work is merely shifted into correcting AI mistakes, a faster model response may not reduce end-to-end effort. This example demonstrates how task, output, decision, controls and outcome connect; it is not an instruction to deploy a particular architecture.

== When an AI use case is appropriate ==

A use case is worth examining when a defined task is materially constrained by information volume, variation, complexity or scale, and an AI capability may improve a relevant outcome. There should be a plausible route from technical output to operational effect. The existence of accessible AI software, market enthusiasm or a vendor demonstration does not establish that an organization needs the proposed use.

Comparison with alternatives is important. A clearer process, a conventional rule, a better search index, improved data quality or simple [[Robotic Process Automation (RPA)|workflow automation]] may solve a problem more reliably and cheaply. For a repetitive process with stable decision rules, AI's flexibility may offer little incremental benefit. For variable documents or uncertain patterns, it may offer a credible advantage if the task can be evaluated and the consequences of error managed.

The potential value depends on the decision at the end of the chain. If an AI model merely returns an interesting prediction without anyone being able or authorized to act on it, the use case may lack a workable benefit pathway. Conversely, augmenting a human decision can create value without replacing the decision-maker. Technical feasibility, organizational readiness, risk and potential outcomes should be assessed together rather than treated as interchangeable scores.

== Feasibility and operational readiness ==

Several dependencies determine whether a proposed use can work in practice:

* '''Suitable information.''' Inputs must exist, be sufficiently accurate and representative, and be lawfully usable for the intended purpose. Sensitive data may need additional access and retention controls.
* '''Task-specific evaluation.''' Success criteria, test cases, comparison methods and acceptable error types should be defined for the actual work, not inferred from a general model benchmark.
* '''Workflow integration.''' Users need a dependable way to receive, challenge, override or act on results; interfaces and authorization must match the task.
* '''Operational capacity.''' Teams need owners for incidents, model or vendor changes, retraining or configuration, service-level obligations and business continuity.
* '''Cost and dependency.''' Acquisition, integration, computation, human review, vendor reliance, monitoring and exit costs affect the net result.
* '''Context-specific rules.''' Applicable law, employment or customer obligations, contractual terms and sector controls may determine whether a use is allowed or needs additional review.

These are feasibility conditions rather than a complete implementation guide. A more detailed [[AI Assessment|AI assessment]] or [[AI Use Case Assessment|use-case assessment]] may establish the evidence needed for an organizational decision. An apparent lack of model accuracy may indicate unsuitable inputs or a poorly framed task rather than an intrinsic limit of the entire AI field. Equally, a favorable experiment does not remove constraints on deployment at organizational scale.

== Responsibilities and decision rights ==

An AI use case needs accountable roles because technology, business process and risk decisions are rarely owned by the same person. Exact titles vary by organization; the following describes functions rather than an imposed governance chart.

{| class="wikitable"
! Role or function
! Responsibility for the use case
! Important handoff
|-
| '''Business or service owner'''
| Defines the need, acceptable outcome, process changes and decision consequences
| Accepts or rejects whether the operating result meets the intended need
|-
| '''Data or information owner'''
| Determines permitted information use, quality, provenance and retention
| Confirms access and data suitability for the defined task
|-
| '''Technology or AI delivery function'''
| Builds, configures or integrates the system and tests task behavior
| Provides evidence of technical fitness, limits and change management
|-
| '''Security, privacy, legal and risk functions'''
| Review obligations and foreseeable harmful or unauthorized uses according to their authority
| Identify controls and conditions needed before or during operation
|-
| '''Operations and support'''
| Monitor live use, incidents, changes, availability and correction pathways
| Escalate exceptions and retire unsafe or ineffective implementations
|-
| '''Users and affected stakeholders'''
| Supply information about real work, errors, usability and impacts
| Challenge outcomes and report unintended consequences
|}

The person who approves a use case should not assume that a product vendor has accepted every organizational risk. A vendor may warrant particular product behavior, but business decisions, local data rights, role delegation and the consequences of using outputs in a specific workflow remain context dependent. [[AI Governance|AI governance]] provides the wider authority and oversight system within which uses are assessed and controlled.

== Risks, controls and responsible use ==

Risk depends on what the AI is asked to do, which information it accesses and what happens when it is wrong. A document-drafting assistant and an AI-supported decision about employment eligibility have different consequences even if they use the same underlying model. NIST's AI RMF 1.0 addresses risks through ''Govern'', ''Map'', ''Measure'' and ''Manage'', and supports contextual use-case profiles for specific applications.<ref name="nistprofiles">National Institute of Standards and Technology (NIST) (2023), ''AI Risk Management Framework 1.0: AI RMF Profiles'', section 6, describing context-specific use-case profiles and current/target profiles. [https://airc.nist.gov/airmf-resources/airmf/6-sec-profile/ NIST AI RMF]. Accessed 9 November 2026.</ref>

Material concerns can include incorrect or unsupported outputs, hidden discrimination, privacy or intellectual-property exposure, security compromise, unreliable automation, weak explainability, inaccessibility, user overreliance and inadequate contestability. Each concern must be linked to the particular task and affected people. A model can be accurate on average and still be inappropriate where errors fall disproportionately on an exposed population or where an adverse decision cannot be challenged.

Controls may include data minimization, access restrictions, evaluations on relevant populations, explicit human review, safety thresholds, audit trails, independent tool permissions, incident escalation and mechanisms to reverse or suspend use. The control should operate where the risk arises: a review instruction inside a prompt does not, by itself, make an unauthorized transaction impossible. For tool-using [[AI Agent|agents]], [[AI Agent Security|agent security]] includes additional identity, permission and action-control requirements.

An AI use case description should identify the decision's consequences and required safeguards, while a full [[AI Risk Assessment|AI risk assessment]] may examine severity, exposure, mitigations and residual risk in greater detail. Security or compliance review must not be mistaken for proof that the use will generate business value.

== Measuring outcomes and benefits ==

A use case's measures should follow the reason it exists. Technical accuracy or answer quality is necessary for many tasks, but it is rarely the entire evaluation of a business or public-service result. Measurement should consider the complete process, including human review, integration, failed cases, and the costs or harms introduced.

{| class="wikitable"
! Measurement level
! Examples
! What the measure cannot establish on its own
|-
| '''AI task performance'''
| Accuracy, recall, precision, calibration, groundedness, error rate or test success, as relevant
| That a real process has improved
|-
| '''Workflow operation'''
| Reassignment rate, handling time, override frequency, exceptions, backlog or uptime
| That quality, fairness or user outcomes have improved
|-
| '''Business or public-service outcome'''
| Quality-adjusted throughput, cost per completed case, avoided loss, customer result or accessibility
| That AI alone caused the observed change
|-
| '''Risk and control performance'''
| Harmful incidents, privacy violations, unauthorized actions, successful escalation or reversals
| That harms are absent when reporting or detection is incomplete
|-
| '''Net value and sustainability'''
| Benefits after software, infrastructure, integration, human labor, maintenance and opportunity cost
| That the result will persist across time, teams or populations
|}

A baseline should specify population, observation window, task definition and current method. A comparison may use a controlled experiment, matched cohort, before-and-after observation or another defensible design. The choice affects what can be inferred: improvement after deployment may coincide with staffing, demand or process changes. Results should be reported with their scope and uncertainty rather than as a universal AI return on investment. The peer-reviewed customer-service study cited above is an example of a bounded measured outcome, not evidence that all comparable projects will reproduce its effect.<ref name="qje" />

== Use-case lifecycle and status ==

An AI use case can move through several states without changing its identity. Labels vary among organizations, but the distinctions between a proposal, trial and production use should remain visible. NIST's risk-management guidance treats context, evaluation and risk management as continuing concerns throughout the AI lifecycle.<ref name="nistmap" />

{| class="wikitable"
! Illustrative state
! Meaning
! Evidence normally available
|-
| '''Proposed'''
| A defined need and candidate AI contribution have been identified
| Problem, owner, intended outcome and initial feasibility or risk assumptions
|-
| '''Under assessment'''
| Applicability, data, controls and alternatives are being examined
| Evidence gaps, options and decision conditions
|-
| '''Pilot or experiment'''
| A bounded test is performed without assuming general operational approval
| Representative task results and observed failure cases
|-
| '''Deployed'''

|-
| '''Changed or expanded'''
| Material modifications alter data, users, tools, permissions or decisions
| Reassessment of changed scope and new risks
|-
| '''Suspended, retired or replaced'''
| Use is paused, withdrawn or superseded
| Decision rationale, access removal, records and dependency handoff
|}

A public AI use-case inventory may count research projects or paused cases alongside deployed uses. GAO's 2026 IRS analysis observed entries still in development, projects no longer progressing and classification inconsistencies. Without status and definition information, raw inventory counts can create a misleading impression of actual deployment.<ref name="gao2026" />

== AI use-case inventories and portfolios ==

An [[AI Use Case Inventory|AI use-case inventory]] records known uses across the organization and supports accountability, duplication checks, security review and lifecycle tracking. Depending on the organization it may include proposed and prohibited uses, deployed applications, procurement-embedded AI and third-party tools. Public-sector inventories are examples of this practice, but their disclosure rules and exclusions vary.<ref name="gao2026" /><ref name="fed2025" />

A use-case record normally links a persistent identity to its owner, task and context, implementation or vendor references, data and access boundaries, risk classification, lifecycle state, approval history, evaluation results and next review. An [[AI Use Case Portfolio|AI use-case portfolio]] connects multiple records to priorities, dependencies and available capacity without turning unrelated uses into one generic program. The inventory is a management record; it is not, by itself, proof that a use is compliant, valuable or operational.

A single enterprise AI assistant may support several uses, while an AI use case may depend on multiple systems. Inventory design should therefore allow those many-to-many relationships. Otherwise, tracking only products can hide sensitive tasks, and tracking only business departments can obscure shared dependencies. GAO's findings about omitted IRS uses and missing benefit descriptions illustrate these information-quality risks.<ref name="gao2026" />

== Common problems and failure patterns ==

Several weaknesses recur when the idea, technical system and operational result are conflated:

* '''Technology-first description.''' ''Deploy an LLM'' names an approach without specifying the decision or problem. The resulting project may be impossible to evaluate against a meaningful need.
* '''An undefined scope.''' ''AI for customer operations'' can contain many uses with different data, populations and controls. A broad category is not a sufficient approval unit.
* '''Assumed benefits.''' A vendor demonstration or benchmark is interpreted as demonstrated labor or financial savings. Actual outcomes and displaced costs remain unobserved.
* '''Unexamined alternatives.''' Conventional software, process repair or better information access may be more reliable and cost-effective.
* '''Incomplete information.''' The use lacks an owner, input provenance, intended benefit, lifecycle status or affected population. Evaluation and risk treatment become guesswork.
* '''Unclear authority.''' A recommendation becomes an automated decision without a corresponding change in access, approval, accountability or redress.
* '''Success measured too narrowly.''' Faster output hides additional review labor, inaccurate escalations, reduced quality or uneven harm.
* '''Uncontrolled change.''' A new model version, data source, vendor feature or expanded user group changes the actual use while the original assessment remains unchanged.

GAO found that more than a quarter of the IRS use-case entries it reviewed lacked information describing the expected benefit, and that some uses were absent from its inventory.<ref name="gao2026" /> This finding illustrates why a use-case register must carry enough information to support decisions rather than merely accumulate names.

== Frequently asked questions ==

=== What is an AI use case in simple terms? ===

It is a clear description of one job an organization wants AI to help perform and the outcome it expects. It connects the need, input, AI contribution, people involved, decision and measure of success.

=== What is a good example of an AI use case? ===

A service desk using AI to classify incoming incident reports and suggest an initial support group is a specific example. To be complete, the description should identify who reviews uncertain cases, what data the AI may read, and whether the new routing actually improves results.

=== How is an AI use case different from an AI application? ===

No. An application is the software used to perform functions. A use case explains a particular purpose for using that software within a process. One application may support many uses; one use may depend on several applications or models.

=== Does an AI use case need to be in production? ===

No. A proposed or experimental use can be documented as a use case for artificial intelligence if its intended task and scope are clear. It should be explicitly labeled as proposed, in development, piloted or deployed so readers do not mistake an idea for a proven operating result.

=== Can one AI model support several AI use cases? ===

Yes. A language model might draft customer-service replies, summarize legal materials and assist software developers. Those purposes may require separate users, data permissions, tests and governance decisions even when the same model is reused.

=== Are AI use cases only about generative AI? ===

No. AI can classify information, detect anomalies, predict events, recommend actions, recognize images, optimize routes, generate content and support other tasks. Generative AI is only one family of capabilities.

=== How is an AI use case different from an AI business case? ===

The use case identifies what AI would do and what outcome is sought. A business case weighs whether the organization should invest, considering alternatives, expected value, costs, uncertainty and risks. The same use case may be reconsidered in several funding or sourcing decisions.

=== How do organizations know whether an AI use case works? ===

They define relevant task and business measures, establish a defensible baseline, test the use in representative conditions, examine errors and adverse effects, and monitor real outcomes after deployment. A successful demonstration or model benchmark does not alone prove a net benefit.

=== Can AI be the wrong solution to a valid use case? ===

Yes. The underlying operational problem may be real while the proposed AI approach is unsuitable. Conventional automation, clearer rules, a redesigned process or better-quality information may offer a safer or more economical solution.
