Overview

These study notes address the critical difference between verification and validation within software quality assurance. Rather than relying on simple memorized slogans, the guide defines verification as checking whether a work product meets its stated requirements, while validation examines whether the product satisfies intended user needs and business goals in realistic environments. It corrects common misconceptions, such as assuming verification only involves documents or that dynamic testing represents validation exclusively. The material provides an answering framework and walks through practical interview scenarios spanning checkout workflows, API contracts, paper prototypes, reporting dashboards, offline mobile apps, acceptance sign-offs, and accessibility. Each scenario outlines specific verification checks, validation investigations, tricky points, and sample interview answers designed to demonstrate nuanced, evidence-based QA thinking.

What you'll learn

Distinguish verification from validation using reference points instead of testing methods.
Avoid the trap of equating verification with static and validation with dynamic testing.
Formulate structured interview answers using evidence, requirements, and user needs.
Evaluate early designs and paper prototypes to perform validation before coding begins.
Differentiate technical requirement conformance from operational usefulness in reporting and APIs.
Identify gaps in specified requirements through realistic environment trials and user walkthroughs.

Topics covered

verification
validation
qa interviews
test design
requirements analysis
software testing

Two questions to keep separate
The difference that matters
Purpose is different from method
01. The correct but unusable checkout
02. An API returns HTTP 200
03. Find the problem before coding
04. An accurate report nobody can use
05. It works only on office Wi-Fi
06. The customer signs off
07. A working feature excludes users

Selected preview

Verification checks whether a work product satisfies its stated requirements, asking if specified behavior has been implemented correctly. Validation checks whether the proposed or delivered product supports users' actual goals in the expected environment, as a technically correct feature can still solve the wrong problem.
