Definition
The Validation Lifecycle describes planning, execution, maintenance and periodic review of Validation throughout the operating life of a solution.
Human Explanation
Validation continues after initial approval because the solution, its use and its environment can change.
Why it Matters
Lifecycle control keeps the validated state aligned with current Requirements and Risk.
Conceptual Boundary
The lifecycle is broader than testing or acceptance and includes change, review, maintenance and retirement considerations.
Practical Perspective
Review points, change triggers, responsibilities and conditions for revalidation should be defined in advance.
