Start with a specific outcome, a clearly bounded use case, and evidence that the system can meet the need safely with the people and resources available. An AI project is finishable when its task, users, limits, dependencies, acceptance tests, and operating responsibilities are defined before the team commits to a wider ambition. NIST’s AI Risk Management Framework (AI RMF) offers a useful, voluntary structure for doing that; it does not prescribe a universal project schedule, team size, or minimum viable product process.
What belongs in an AI project scope?
A scope is more than a model choice or feature list. It should explain why the system is being built, who will use it, what task it supports, where it will be used, what it must not do, and how the team will decide whether it is ready. NIST’s AI RMF Core calls for documenting the context, intended purpose, requirements, benefits and costs, potential impacts, risk tolerance, target scope, and expected human oversight.

- Outcome: the user need or organizational benefit the project is meant to address.
- Use context: users, setting, workflow, affected people, and relevant requirements or norms.
- Boundary: the task the system will support, its intended application scope, and what is out of scope for the first release.
- Limits and oversight: what the system is not expected to know or do, who reviews its output, and what happens when it is uncertain or unavailable.
- Evidence and operations: acceptance criteria, evaluation and monitoring plans, accountable roles, dependencies, and the resources assigned.
NIST’s framework is voluntary and should be adapted to the organization, use case, available resources, and risk tolerance. It is not a substitute for legal analysis: applicable obligations vary by jurisdiction and use. The framework’s landing page says AI RMF 1.0 is being revised, so check NIST’s status pages rather than assuming that version is the latest: AI RMF development and the AI RMF landing page.

1. Define the outcome and the boundary
Write a short statement naming the user, the situation, the intended benefit, and the decision or task the system will support. Then name the initial application boundary: for example, which users or workflow are included, and which adjacent tasks, audiences, or decisions are excluded. State the business or mission context and the organization’s tolerance for risk. This prevents a broad aspiration such as “use AI to improve support” from silently turning into several different products.

2. Check capability, data, and dependencies
Identify the proposed model or method and what it can and cannot reliably do in this particular context. Record the data needed, whether it is suitable and available, and any knowledge limits that could affect outputs. Map third-party data, software, hardware, and services, including legal and technical dependencies. Specify where a person must review results, when the system should defer, and what fallback process applies if a component fails. These are scope questions because they affect what can be delivered and operated—not just later implementation details.
3. Make feasibility a decision, not an assumption
Compare the expected benefit with capability, data readiness, integration work, risk, cost, available expertise, and the people and resources actually assigned. A technically possible system may still be infeasible if the team cannot secure appropriate data, integrate it into the workflow, evaluate it, or staff its oversight. For security practices, NIST’s Secure Software Development Framework (SSDF) says teams should consider cost, feasibility, and applicability as well as risk. It is a planning basis to tailor, not a requirement to apply every practice identically: NIST SSDF.
4. Define “done” as evidence
Set acceptance criteria that match the actual use context before development makes a preferred solution feel inevitable. Choose measures and benchmarks relevant to the task; determine how the team will examine reliability, uncertainty, robustness, safety, privacy, fairness, security, and human oversight where those concerns apply. Record known limitations and the conditions beyond which results should not be generalized. Plan tests before deployment and regular evaluation during operation. NIST’s AI RMF Core supports testing both before deployment and while a system is operating.
5. Assign risk and delivery responsibilities
Name the people accountable for scope decisions, testing, approvals, monitoring, and incident handling. Prioritize risks by potential impact, likelihood, and available resources, then decide whether to mitigate, avoid, transfer, or accept each one. NIST describes Govern, Map, Measure, and Manage as connected, iterative functions, with governance continuing throughout the AI lifecycle; risk decisions therefore belong in delivery and operations, not in a one-time kickoff document.
6. Gate expansion on results
Begin with a bounded use, then make expansion conditional on evaluation results and operational capacity. Add users, tasks, autonomy, or integrations only when the evidence supports the change and the team can sustain the added oversight and risk work. This is a practical application of NIST’s emphasis on scope, capability, risk tolerance, and iterative evaluation—not a universal MVP procedure prescribed by NIST.
How to choose between rules, machine learning, and generative AI
Compare approaches against the same outcome and context instead of assuming that the newest or most capable-sounding option is the right one. The sources do not establish one universally preferable approach. Use the following dimensions to make the trade-offs explicit:
| Decision factor | Questions to answer |
|---|---|
| Outcome fit | Can this approach meet the intended outcome within the defined task and application boundary? |
| Data | Is suitable data available, lawful to use, and adequate for development and evaluation? |
| Reliability and uncertainty | How dependable are results in the target context, and how will uncertainty or failure be detected? |
| Consequences of errors | Who could be affected by a wrong result, and what harm could follow? |
| Human oversight | What review, approval, escalation, or fallback is needed? |
| Security, privacy, and legal dependencies | What data, software, providers, and applicable requirements must the team account for? |
| Operations | What ongoing monitoring, evaluation, maintenance, and incident response will be required? |
| Cost and expertise | Can the organization afford the full lifecycle work and provide the necessary skills? |
A rules-based workflow, conventional machine-learning model, and generative AI system can each be a candidate, depending on the task and evidence. Generative AI deserves particular care because its risks can arise at different stages and scales, and some risks may be unknown or difficult to evaluate. NIST’s generative AI profile discusses those concerns: NIST AI 600-1.
Keep the scope alive through the lifecycle
Scope is a working agreement, not a promise that the initial plan will remain correct as evidence arrives. Revisit it when tests reveal a capability gap, data or third-party dependencies change, the use context expands, or operating risks differ from expectations. If the change increases the system’s task, audience, autonomy, or impact, update the acceptance criteria, oversight, and assigned capacity before proceeding.

NIST published the AI RMF 1.0 on January 26, 2023; its generative AI profile, NIST AI 600-1, followed on July 26, 2024. For secure development practices tailored to generative AI and dual-use foundation models, NIST published SP 800-218A on July 26, 2024: NIST SP 800-218A. These documents can inform planning, but they do not provide a guaranteed timetable or a formula for how many people a project needs.
