Candidate Use-Case Identification for Health AI Projects

Candidate use-case identification is the first and most consequential step any health organization takes before committing budget, staff time, or executive attention to artificial intelligence. It is the structured process of finding, describing, and ranking the specific problems AI might realistically solve — instead of buying a tool first and hunting for a justification afterward. For health systems, life-science companies, payers, and academic medical centers, getting this step right determines whether the next twelve months of AI investment produce measurable patient benefit or an expensive shelf project nobody ever opens again.

Candidate use-case identification works best when clinicians and community members sit at the same table.

What Is Candidate Use-Case Identification?

Candidate use-case identification is the discovery phase where an organization maps real operational and clinical pain points, then filters them to find which ones AI could realistically address. In particular, this phase happens before any vendor conversation or technical build begins. According to guidance published by the World Health Organization, a large share of health AI pilots never reach routine clinical use, and unclear use-case selection is cited as a leading cause of that failure rate.

As a result, organizations that skip this step often discover misalignment only after money and staff time are already spent. Consequently, treating identification as its own deliberate phase, rather than an afterthought squeezed into a kickoff meeting, is what separates AI programs that stick from those that quietly die after the first pilot.

Where the Idea Comes From: Use-Case Modeling in Software Engineering

It helps to know the lineage of this term. In software engineering, a use case is a documented interaction between an "actor" (a person or system) and a system, aimed at achieving a specific goal. Traditional use-case modeling, built into the Unified Modeling Language, asks teams to identify actors, map their goals, and describe step-by-step scenarios before a single line of code is written.

Candidate use-case identification borrows that discipline but applies it to a much higher-stakes environment: clinical care, patient trust, and regulatory oversight. The word "candidate" matters here. Unlike a confirmed use case in a requirements document, a candidate is only a hypothesis — an idea worth testing, not yet a commitment worth funding. In other words, every candidate must earn its place through evidence, not enthusiasm, before it becomes a funded pilot.

Why Candidate Use-Case Identification Protects Health Equity

Health equity, meaning fair access to care and outcomes regardless of background or circumstance, is not a separate add-on to AI strategy. Rather, it is a condition of performance that must be built into identification from the start. For example, a scheduling optimization tool might look efficient on paper while quietly deprioritizing patients without reliable transportation or internet access.

Therefore, the AI4EQUITY™ Implementation Framework treats trust, accountability, and cultural context as inputs to be measured alongside accuracy and cost, not as soft concerns to revisit later. In addition, this framework draws on community-based participatory research, an approach documented extensively by the National Institutes of Health, which emphasizes involving affected communities as partners rather than subjects.

The Six-Step Process for Identifying AI Use Cases

Below is a practical, six-step sequence built on the AI4EQUITY™ pillars. Each step produces a specific output that feeds the next one, so teams are never guessing what comes after the brainstorming session ends.

1. Evaluation: Gather frontline staff, clinicians, and community members to list the real operational and clinical problems they face daily, without mentioning any specific technology yet.
2. Quantify: Attach rough numbers to each problem, such as hours lost, patients affected, or dollars spent, so the group can compare candidates on a common scale.
3. Understanding: Map the existing workflow and data sources tied to each candidate use case to confirm whether the information needed actually exists and is accessible.
4. Identity: Ask who benefits and who bears risk for each candidate, paying close attention to populations that have historically been underserved by health systems.
5. Translation: Translate the strongest candidates into plain-language problem statements that a board, funder, or community group could understand without technical background.
6. Yield: Rank the finalists by expected yield, combining feasibility, equity impact, and cost, then hand the short list to the team responsible for the next assessment phase.

For organizations that want a closer look at what happens once candidates are ranked, the next stage is typically covered in detail in this guide on what is involved in an AI opportunity assessment for health systems.

Ranking candidates by feasibility, equity impact, and cost narrows a long list to a workable short list.

How Use-Case Identification Differs From an Opportunity Assessment

Candidate use-case identification generates the shortlist; an opportunity assessment then stress-tests each item on that list. Specifically, the assessment phase digs into return on investment, regulatory risk, and technical feasibility for each surviving candidate. Readers tracking the financial side of this work may find it useful to review this breakdown of how to measure ROI for AI opportunity assessments in health.

Similarly, organizations that rely on causal loop mapping to understand how one AI decision ripples through a clinical system can explore this resource on causal loop mapping for healthcare AI ethics, which pairs naturally with the identification phase described here.

Proven Techniques for Identifying Candidate Use Cases

Workshops alone rarely surface every opportunity. In contrast, pairing a workshop with one or more structured techniques, borrowed from classical use-case modeling and adapted for clinical settings, consistently produces a richer, more defensible candidate list.

Goal-Based Identification

This technique starts by asking each stakeholder group what they are actually trying to accomplish, not what tool they want. For example, a care coordinator's real goal might be "reduce missed follow-up appointments," never "buy a chatbot." Because the goal is named first, the resulting candidate use case stays anchored to outcomes instead of features.

Event-Based Identification

Here, teams walk through a timeline of triggering events — a patient is admitted, a lab result returns abnormal, a prescription is about to lapse — and ask whether AI could improve the response to that specific moment. This approach is particularly useful for surfacing candidates hidden inside routine clinical workflows that nobody thinks to mention in an open-ended brainstorm.

Actor-Based (Boundary) Identification

In classic use-case modeling, teams list every "actor" that touches the system — users, administrators, external systems — then ask what each actor needs from it. Applied to health AI, this means listing every role that touches a process: the nurse, the scheduler, the billing clerk, the patient, the caregiver, even the referring clinic. Each actor's unmet need is a potential candidate waiting to be named.

Data and Workflow (CRUD-Based) Identification

Finally, this technique traces how information is created, read, updated, and deleted across a process. Wherever that data trail breaks down — a duplicate entry, a delayed update, a report nobody reads — there is usually a candidate use case hiding in the gap. Above all, this technique is the fastest way to catch problems that are invisible in a workshop but obvious in the data.

Naming and Documenting a Candidate Use Case

A candidate is only useful if someone outside the room can understand it later. Consequently, every candidate deserves a short, consistent write-up before it moves forward. A reliable template includes:

• Name: a verb-plus-goal phrase, such as "Predict missed chemotherapy appointments," not a product name.
• Primary actor: the role whose goal is being served, such as a care coordinator or scheduling team.
• Trigger: the event that starts the process, such as an appointment being booked.
• Data needed: the sources the use case would require, flagged for readiness and access.
• Equity flag: a one-line note on who might be helped or harmed if the use case is built poorly.

Because this format stays consistent across every candidate, leadership can compare apples to apples instead of reading five differently structured proposals. Likewise, this documentation becomes the raw material for the opportunity assessment that follows identification.

Avoiding Granularity Mistakes: Too Broad, Too Narrow, Just Right

Scope is where most candidate lists quietly fall apart. Specifically, three levels of granularity tend to appear, and only the middle one is usable without further work.

• Too broad: "Use AI to improve hospital operations." This cannot be scored, staffed, or funded because it describes an ambition, not a use case.
• Just right: "Reduce missed diabetes follow-up visits through predictive outreach." This is specific enough to staff, score, and pilot within a defined timeframe.
• Too narrow: "Send one text reminder to one patient tomorrow." This is a task, not a use case, and does not justify strategic investment.

In short, the right level — sometimes called the "user-goal" level in classic use-case modeling — describes a complete, meaningful outcome without dragging in every implementation detail. Teams that land here consistently produce candidates that survive the next round of scrutiny.

How Candidate Use Cases Connect to Each Other

Rarely does a candidate use case stand alone. For instance, a predictive no-show model might extend naturally into an automated outreach workflow, while both depend on the same underlying scheduling data pipeline. Mapping these relationships early — much like "include" and "extend" relationships in traditional use-case diagrams — helps teams spot shared infrastructure, avoid duplicate builds, and sequence pilots so earlier wins fund later ones.

As a result, an organization that maps these dependencies during identification, rather than discovering them mid-build, tends to launch its second and third AI projects far faster than its first.

Common Mistakes During Use Case Identification

Above all, the most frequent error is starting with a tool instead of a problem. A vendor demo can be persuasive, but it rarely reflects the specific workflow, patient population, or data environment of a given organization. In contrast, identification that starts with lived staff and patient experience produces candidates that actually fit.

Other common missteps include skipping a data readiness check, which leads teams to discover mid-pilot that the records they need are incomplete or scattered across incompatible systems. Likewise, failing to name who is accountable once a system goes live leaves no one responsible when something goes wrong, which is precisely the kind of gap that erodes community trust over time. Finally, writing candidates at the wrong granularity, discussed above, quietly sabotages even well-intentioned lists before scoring ever begins.

Who Should Lead Candidate Use-Case Identification?

A fractional Chief AI or Health Equity Advisor often leads this phase, since it requires both strategic distance and clinical credibility. Furthermore, this role lets an organization get senior-level guidance without committing to a full-time hire before priorities are even clear. Organizations evaluating whether this model fits their situation can read more about the benefits of fractional AI strategy executives in life sciences for additional context, or review a wider look at how fractional AI strategy executives support life-science organizations through identification and beyond.

Meanwhile, the U.S. Department of Health and Human Services has published guidance through HealthIT.gov on responsible AI adoption, noting that governance and workflow fit matter as much as model accuracy. That emphasis mirrors the AI4EQUITY™ approach, which treats trust and cultural context as performance conditions rather than optional extras.

How Does This Connect to Broader AI Transformation Work?

Candidate use-case identification is not a one-time event. Instead, it is the recurring first stage of any enterprise AI transformation roadmap, revisited each time new data, regulation, or community feedback changes the landscape. Because health AI moves quickly, organizations that revisit identification annually tend to avoid the sunk-cost trap of defending outdated pilots.

A simple prioritization matrix keeps candidate use-case identification grounded in data, not hype.

Frequently Asked Questions

What is candidate use-case identification?

Candidate use-case identification is the structured process of finding and ranking potential AI applications inside a health organization before any build or purchase decision is made. It weighs clinical value, data readiness, equity impact, and feasibility together rather than chasing the newest technology trend.

Why does candidate use-case identification matter for health systems?

Without it, organizations often fund AI pilots that look impressive in a demo but never reach patients who need them most. A disciplined identification process protects budget, staff time, and community trust by surfacing the projects most likely to succeed.

How long does the candidate use-case identification process take?

Most structured assessments take four to eight weeks, depending on how many departments and data sources are involved. A fractional advisor model can often compress this timeline inside a 90-day action plan.

What is the difference between use-case identification and an AI opportunity assessment?

Use-case identification is the discovery phase that generates a prioritized list of candidates. An AI opportunity assessment typically follows, analyzing each shortlisted candidate in depth for return on investment, risk, and implementation readiness.

What is the difference between a use case and a candidate use case?

A use case, in traditional software engineering, describes a validated interaction between an actor and a system to reach a specific goal. A candidate use case is simply a hypothesis — an idea worth testing — that has not yet proven its data readiness, equity impact, or feasibility.

How granular should a candidate use case be?

A well-scoped candidate sits at the "user-goal" level: specific enough that staff can picture the workflow, but broad enough to deliver meaningful value. "Reduce missed diabetes follow-up appointments through predictive outreach" works well; "use AI" is too broad and "send one text message" is too narrow.

Who should be involved in identifying AI use cases in a health organization?

Clinical leaders, frontline staff, data governance teams, patient and community representatives, and compliance officers should all contribute. Excluding frontline voices is one of the most common reasons AI projects stall after launch.

How much does candidate use-case identification cost?

Costs vary widely based on organization size and scope, ranging from a short facilitated workshop to a multi-week advisory engagement. Many organizations find it more economical than the sunk cost of an AI pilot that never reaches production.

What are common mistakes organizations make during use-case identification?

The most frequent mistake is starting with the technology rather than the human problem it should solve. Other common errors include ignoring data quality, skipping equity analysis, writing candidates at the wrong granularity, and failing to map who is accountable once the system is live.

How does health equity factor into candidate use-case identification?

Equity analysis asks whether a candidate use case could unintentionally widen gaps in access or outcomes for underserved populations. Building this question into identification, rather than adding it later, prevents costly redesign after deployment.

Can a small clinic or nonprofit use this process, or is it only for large health systems?

Smaller organizations benefit even more because resources are tighter and mistakes are costlier relative to budget. A scaled-down version of the process still protects against wasted pilots and misaligned priorities.

What role does data readiness play in candidate use-case identification?

A use case cannot succeed if the underlying data is incomplete, biased, or siloed across departments. Evaluating data readiness early prevents organizations from investing in projects that will stall during implementation.

How does this process connect to a fractional Chief AI Advisor role?

A fractional advisor often leads candidate use-case identification as the first deliverable in an engagement, since it sets direction for every later strategy and roadmap decision. This keeps the organization from paying for full-time leadership before priorities are clear.

What happens after candidate use cases are identified and ranked?

The ranked list typically feeds into a deeper opportunity assessment and then an implementation roadmap. Each stage narrows the field until the organization is left with a small set of pilots worth funding.

Bringing It All Together

In summary, candidate use-case identification is not a formality to rush past on the way to a flashy pilot. Rather, it is the groundwork that determines whether an AI investment serves patients, staff, and community trust, or simply collects dust after launch. By evaluating real problems, quantifying their scale, checking data readiness, naming who is affected, translating findings into plain language, and ranking by expected yield, health organizations give every later AI decision a solid foundation.
