Root Cause Analysis In CAPA

Root cause analysis helps CAPA find the real reason a quality problem happened so the cause can be fixed and the same problem is less likely to happen again.

It gives the investigation a structured way to move beyond the immediate symptom, examine the factors connected with the event, and identify the cause that should guide further CAPA action.

Problem Investigation

Root cause analysis helps CAPA investigate a quality problem by examining what happened, where it occurred, and which conditions may have contributed to the event.

The investigation can review relevant records, procedures, processes, materials, equipment, personnel, and other information needed to understand the problem before a cause is selected.

Contributing Factors

Root cause analysis examines contributing factors to determine which conditions influenced the quality problem and which may only be associated with it.

These factors can involve people, methods, materials, equipment, environment, procedures, or process controls. Reviewing them helps narrow the investigation toward the factors most closely connected with the failure.

Root Cause Identification

Root cause analysis helps CAPA identify the underlying reason a quality problem occurred instead of treating only its visible symptom.

The identified cause should explain why the event happened and provide a logical connection between the available evidence and the quality problem being investigated.

Cause Verification

Cause verification helps confirm that the suspected root cause is supported by evidence before the CAPA investigation relies on it.

The investigation can compare the suspected cause with records, process data, observations, testing, or other available evidence to determine whether it reasonably explains the failure.

Recurrence Prevention

Identifying and verifying the root cause helps CAPA reduce recurrence by providing a clear basis for actions directed at the source of the problem.

When the underlying cause is addressed rather than only the immediate symptom, the organization is in a better position to reduce the likelihood of the same quality issue occurring again.
