Deviation Investigations
Deviation backlogs grow when investigations are slow, root cause is shallow, and CAPAs do not stick. This section covers how to build investigation systems that close loops faster, find real root cause, and reduce recurrence rates.
Deviation Backlogs Are Not Linear: Understanding the Hidden Factory in GMP Investigations
April 1, 2026 • By Mike Barlow
Deviation investigations are often managed as a linear workload—one record, one investigation, one unit of effort. This assumption holds only while the system operates within capacity. Once backlog forms, the system behavior changes. Effort no longer scales with the number of deviations; it expands nonlinearly as coordination, prioritization, and aging effects take over. The result is a Hidden Factory—capacity consumed not by resolving deviations, but by managing them. Understanding this shift is critical: restoring performance is not about working harder, but about re-establishing flow in a system that has crossed into exponential cost.
What is a GMP Deviation Investigation?
August 26, 2023 • By Mike Barlow
In GMP pharmaceutical production, including biologics and cell therapy manufacturing, a GMP Deviation Investigation is the structured process used to identify, document, analyze, and resolve any unexpected events or conditions that do not comply with approved procedures, specifications, or regulatory requirements.
