Day 13: Turn Requirements Into Testable Acceptance Criteria

The Concept

Requirements are where intention meets implementation. They need enough clarity for people to build and test the right thing, but they also need to remain connected to the user or business outcome.

AI is useful at finding vague language, repeated requirements, missing conditions, and hidden assumptions. It is not a substitute for the people who understand the user, the domain, or the technical constraints.

Make completion observable

“The process should be easy to use” is a reasonable aspiration but a weak acceptance criterion. “A first-time user can submit the request without assistance and receives confirmation” is more observable. The goal is not to remove all judgment. It is to reduce avoidable disagreement about whether the work is ready.

Separate needs from solutions

Requirements often contain a solution too early. "We need a dashboard" may actually mean "leaders need a reliable weekly view of performance." Ask AI to identify the underlying need before accepting the proposed solution.

Example: move from preference to evidence

Consider the requirement: “The system should allow managers to see all employee requests in one dashboard.” It contains a useful direction, but several questions remain. Which managers? Which requests? How current must the information be? What action should a manager take after seeing it? What must be hidden from people without the right access?

A clearer version might say: “A regional manager can view the open requests for their region, filtered by status and owner, and can identify requests that have been waiting more than five business days.” Acceptance criteria could then check that the correct requests are visible, the filters return the expected results, restricted records do not appear, and the waiting-time indicator is calculated according to an agreed rule.

The example does not provide technical implementation. It provides observable behaviour and exposes decisions the owner still needs to make.

Test the edges, not only the happy path

Ask what should happen when information is missing, late, duplicated, invalid, or outside the user's permission. Ask what happens when a user has no matching records or when two people update the same item. AI is useful for generating edge-case questions, but a domain expert must decide which cases matter and what the correct behaviour should be.

Keep non-functional needs visible

Requirements are not limited to screens and actions. A project may also need accessibility, performance, auditability, privacy, reliability, or supportability. Do not allow these qualities to appear only as a vague “the system should be secure” sentence. Ask how the quality will be observed, who owns the standard, and what evidence is needed before release.

Manage change deliberately

A new request is not automatically a problem, but it can change effort, sequence, risk, or the expected outcome. When a requirement changes, record what prompted the change, what it replaces, and what trade-off it introduces. Use AI to compare versions and highlight differences, then let the owner decide whether the change belongs in the current release or a later one.

A final check before sharing

A requirement is ready for discussion when a builder, tester, user representative, and decision-maker can describe what success means in similar terms. It does not need to answer every question immediately. It does need to make the remaining questions visible, owned, and small enough to resolve.

Trace the requirement to the outcome

For important requirements, record the link between the user need, the requirement, the acceptance criteria, and the evidence that will be reviewed. This trace does not need to become bureaucracy. A simple identifier or table can show why the work exists and how the team will know it helped.

Traceability is especially useful when people propose cuts. If a requirement is removed, ask which outcome or risk it supported. If the outcome remains protected, the cut may be reasonable. If the outcome is now exposed, make that trade-off visible before accepting the change.

Use AI to compare the requirement set with the project objective and highlight orphaned items or uncovered needs. Treat the result as a prompt for review. The product owner and delivery team still decide what belongs in scope.

Clear acceptance criteria give the team a shared finish line and make later trade-offs easier to explain.

Keep the criteria close to the requirement so that they travel together through planning, build, test, and release review.

This also helps new team members understand why a piece of work matters.

The finish line should be visible before the team starts building.

That visibility is what makes testing meaningful.

It also gives stakeholders a fair basis for accepting the result.

That is a small discipline with a large payoff.

Use this today

Take five requirements and mark each as clear, ambiguous, assumed, or out of scope. Then ask the owner the smallest question that would move each item forward. Good requirements work is often a series of precise questions.

Remember this

• Requirements should connect user need to observable evidence.
• Do not let a proposed solution hide the real problem.
• Testable language reduces rework and difficult conversations later.
