Meaning
A gradual divergence occurs when an operational workflow slowly changes over time from its documented or intended design. This phenomenon, known as process drift, is typically driven by undocumented workarounds, minor employee adjustments, or uncoordinated tool upgrades. It is difficult to detect in the short term because the system continues to function even as the underlying steps change.
Over time, these unauthorized variations can compromise the integrity of safety checks and quality controls.
Systemic Origin
Individual adjustments are often made to solve immediate local problems without consideration for how those changes affect downstream systems. Over several months, these small changes accumulate until the actual operation bears little resemblance to the official procedure. This process drift happens naturally in any organization that lacks continuous monitoring and regular refresher training.
Negative Outcome
Increased error rates and inconsistent product quality are the primary consequences of this unmanaged divergence. When the workflow deviates from the standard, troubleshooting becomes difficult because support engineers are unaware of the non-standard steps being used by the operational team. This lack of transparency can lead to prolonged resolution times and customer dissatisfaction.
Remedial Action
Correcting this issue requires a formal audit to compare the active workflow against the documented procedure and update either the documentation or the training program.
