Challenge
A product family experienced repeated batch holds due to deviations, which blocked planned tech transfers to secondary manufacturing sites and threatened continuity of supply for key markets.
Approach
We performed rapid root-cause investigations to identify systemic contributors to deviations, implemented immediate containment measures to allow limited releases, and designed prioritized CAPA packages focused on the highest-impact failure modes. We standardized deviation investigation templates, accelerated analytical method re-qualification where needed, and documented closure packages in regulator-friendly formats. We coordinated with tech-transfer teams to integrate improved control descriptions and acceptance criteria into the transfer dossiers.
Impact
The backlog of held batches was cleared, release controls were strengthened so batches could be released with defensible evidence, and the tech-transfer packages were validated—enabling the planned transfers without regulatory holds and restoring the client's ability to scale supply.
