Change Control Management: What Gets Companies in Trouble

The most dangerous change in a GMP plant is not the big capital project everyone debates for a year — it is the small one nobody logged, because someone called it like for like. Marcus and Priya walk through change control management: what the system is actually for, the invisible changes that escape it, where impact and risk assessment do the real work, the timing failures inspectors cite, honest rules for emergency and temporary changes, and how to keep control without freezing the plant. • What change control actually is: 21 CFR 211.100, EU GMP, and ICH Q10 — and why the validated, registered state is the thing being protected • The invisible changes: like-for-like claims, temporary changes that never leave, software and spreadsheet changes, supplier notifications, and "editorial" edits • Assessment, where the real work is: cross-functional impact, the regulatory filing question, and risk assessment under ICH Q9 • Timing failures: implementation before approval, training after the effective date, and the open tail of never-closed changes • Emergency and temporary changes: a faster door into the same system, expiry dates, owners, and end states • ICH Q12: established conditions and post-approval change management protocols — less theatre, more precision • What good looks like: a change log leaders test against floor reality, post-implementation effectiveness review, and change metrics in front of leadership New episodes every Monday and Wednesday — follow The GMP Insider so you never miss one.
