Validating application design against specifications
Few things are harder to recover from than discovering you’ve missed critical requirements, risk-mitigating features, or essential tests just when you think your development work is complete.
It takes much less maintenance effort to maintain traceability as your requirements, designs, and tests evolve than it does to patch critical holes in design and development at the 11th hour.
“Clear, complete, unambiguous, testable requirements are a key component in a successful development project.
Inadequate requirements lead to wasted time, design errors, extensive rework, and fragile or error-prone products.” –Megan Martin, V&V Consultant we’re going to do it,” says Megan.
Planning for verification occurs throughout the project life cycle.
You’ll develop the test plan, which captures critical milestones.
The plan must be updated whenever changes are made to design inputs. It’s conducted using the methodology of choice (Scrum, Waterfall, hybrid, etc.).
These can then be used to speed the product development process as well as provide test evidence during formal testing.Defects in the product are resolved and released, and regression testing is performed.A traceability matrix is created to verify that design inputs identified in the verification test plan have been tested and passed.If you develop products — medical devices, particularly — then you’ve heard the terms design validation and design verification (also called V&V).
Here we’ll explain what the two activities are, the difference between them, plus share tips for getting the most out of your efforts.Validation testing would include test cases, test suites, or even clinical trials designed to prove that the product, as built, operates according to the user’s expectations under the conditions where they intend to use it.
