Definition
Validation is the evidence-based process of confirming that a solution, process, system or product meets defined Requirements and is suitable for its intended use.
Human Explanation
It asks whether the result actually fulfils the purpose for which it is needed.
Why it Matters
Validation reduces the Risk of implementing a solution that works technically but does not meet the real needs of users or the organisation.
Conceptual Boundary
Validation is not a single test or a final project stage. It is a lifecycle process covering planning, execution, evaluation, Documentation and continued control.
Practical Perspective
The scope and strength of Evidence should be proportionate to Risk, solution significance, intended use and applicable Requirements.
