Regulated Environment

Details

Also known as: Compliance Environment, Validated Environment, Regulated Industry Development

Core Concepts:

Traceability: Every requirement, design decision, implementation, and test must be linked end-to-end; changes traceable from origin to deployment
Validation & Verification (V&V): Formal proof that a system does what it is intended to do (validation) and is built correctly (verification)
Audit Trail: Immutable, timestamped record of who changed what, when, and why; essential for regulatory inspections
Change Control: Formal process for evaluating, approving, implementing, and documenting any change to a validated system
Documentation requirements: Specifications (URS, FS, DS), SOPs, test protocols, validation reports, and risk assessments are mandatory deliverables
Risk-based approach: Effort and rigor proportional to the risk posed by the system (e.g., GAMP 5 categories, FMEA)
Separation of environments: Strict segregation of development, testing/qualification, and production environments
Reproducibility: Builds, deployments, and test results must be reproducible; version-pinned dependencies and infrastructure-as-code
Electronic signatures & records: Legally binding digital sign-off on documents and data (e.g., FDA 21 CFR Part 11)
Supplier qualification: Third-party components and vendors must be qualified and audited
