2 Prepare users and data
3 Execute scenarios
4 Resolve findings
5 Approve decision

What this resource covers

User acceptance testing evaluates whether the solution supports approved business needs in realistic workflows. It is not a replacement for technical system testing and should not be the first time business users see the product.

  • Define which release scope and acceptance criteria are being evaluated
  • Select knowledgeable business users with decision authority or clear escalation
  • Prepare realistic end-to-end scenarios and safe representative data
  • Provide a stable environment and known limitations
  • Classify findings as defects, requirement gaps, usability concerns, or new requests
  • Retest fixes and record acceptance, conditional acceptance, or rejection

Information to prepare

Bring approved business requirements, user roles, realistic end-to-end scenarios, acceptance criteria, representative data, environment access, known constraints, and authorized business testers.

  • Approved requirements and acceptance criteria
  • System-test evidence and release notes
  • UAT scenarios, users, environment, and data
  • Known issues and workarounds
  • Decision and sign-off authority

Expected planning outputs

Produce an acceptance plan, scenario results, evidence, defect and decision logs, retest outcomes, unresolved-risk acknowledgement, and formal acceptance or rejection by the responsible business owner.

  • UAT plan and execution evidence
  • Finding and decision log
  • Retest results
  • Acceptance decision and conditions
  • Deferred enhancement or change requests

Practical example

How it can be applied

For a clinic workflow, UAT users may register a patient, schedule an appointment, complete a consultation, place an order, review results, produce a bill, and verify role access and reports using controlled test data.

Common mistakes to avoid

  • Using UAT to discover basic technical defects
  • Giving users no preparation or expected results
  • Testing isolated screens instead of business workflows
  • Treating every new idea as a release-blocking defect
  • Requesting sign-off without documenting known issues

FAQ

Common questions

Who should sign off UAT?

The accountable business or product authority should sign, informed by the users who performed the scenarios and the documented findings.

Is a usability request always a defect?

Compare it with approved requirements and acceptance criteria. It may be a defect, a gap, or a new enhancement requiring prioritization.

Can UAT use production data?

Use controlled, authorized, and appropriately protected data. Avoid copying sensitive production data without a valid and secure process.
