Requirements Validation & Sign-Off
Part of the Business Analyst Roadmap
In short
Finding a wrong requirement on paper costs a quick edit. Finding it after the code ships costs weeks. Validation is the checkpoint where stakeholders confirm 'yes, this is what we need'.
Confirming with stakeholders that documented requirements accurately reflect their actual needs before development begins — a formal checkpoint that prevents costly rework from misunderstood requirements.
Think of it like this
Checking the card proof
Before 500 wedding cards are printed, the printer sends one proof. The family checks every name, date and spelling. Fixing a typo now is free. Fixing it after printing means reprinting all 500. Sign-off is approving that proof.

The big ideas
What you need to know
Validation vs verification
Validation asks 'Is this the right requirement?' Verification asks 'Is it written well, clear and testable?' Do both.
Involve builders and testers
Developers check feasibility, testers check testability. They catch problems business readers miss.
Sign-off is a baseline
The approved version becomes the baseline. Changes after this go through change control.
Walk through, don't just email
A 45-minute walkthrough gets real attention. A 40-page email attachment often gets 'looks fine' without being read.
Save yourself the pain
Common mistakes
Oops
Treating silence as approval.
Do this instead
Get an explicit 'approved' from named people, recorded with the document version and date.
Oops
Sending the full document and hoping people read it.
Do this instead
Walk through the key sections live, and point each reviewer to the parts that affect them.
Your mission
Run a peer review

Why should a tester review requirements before development starts?
Go deeper
- 1Draft a validation checklist for reviewing a requirements document with a stakeholder.
- 2Learn why a formal sign-off (even lightweight) creates accountability and shared understanding.
- 3Practice presenting requirements back to a stakeholder for confirmation, not just submitting a document.
