Engineering & Commissioning (GEP)
The qualified state starts at design — risk- and science-based commissioning & qualification.
The qualified state begins at design, not at qualification. Commissioning and qualification that is not risk- and science-based (ASTM E2500 / ISPE Baseline Guide Vol. 5) both wastes effort on the trivial and misses the Critical Aspects that actually protect product — and a qualified state that is not maintained through calibration and maintenance quietly lapses.
The observable evidence a practitioner — or an inspector — would expect at each maturity level. Drawn from the assessment questions themselves.
How are new facilities, utilities, and equipment commissioned and qualified?
No formal commissioning or qualification process
Traditional IQ/OQ/PQ applied uniformly, with little risk basis
Documented C&Q with an impact/risk assessment driving qualification scope
Integrated, risk- and science-based C&Q (ASTM E2500 / ISPE Vol. 5) with Critical Aspects and SME approval
Fully integrated C&Q leveraging engineering and vendor data, with lifecycle verification records and defined requalification triggers
How is Good Engineering Practice applied to design and the maintained qualified state?
Engineering design is ad hoc, with no GEP or hygienic-design basis
Some GEP applied, but design decisions are not consistently traced to requirements
GEP and hygienic-design standards (e.g., ASME BPE) specified in the URS and verified at qualification
Critical Design Elements traced to product/process; maintenance and calibration preserve the qualified state
Lifecycle asset management (incl. digital models) keeps design, qualification, and maintenance state continuously in sync
- ›IQ/OQ/PQ applied uniformly with no impact / risk basis; Critical Aspects not identified.
- ›User Requirements not traced through design to verification.
- ›The qualified state not maintained — calibration and preventive-maintenance lapses.
- ›Hygienic and engineering design standards (e.g., ASME BPE) not specified in the URS or verified at qualification.
