  • Comparative analysis

    Allows identifying at which date differences appeared, or when changes - process, staff, design, etc - were introduced, possibly to have generated the issue.

  • Containment action
    It is the action to mitigate impact of the problem and protect the operations/customers (stop the problem getting worse). Includes correction, immediate corrective action, immediate communication and verification that problem does not degrade.

  • Contributing cause
    Contributing causes are causes that taken alone would not cause the problem but can increase the risk of the issue to happen. Analysis for these causes generally require taking small steps (or a finer look) to be identified and fixed.

  • Control chart

   It is a statistical tool used to distinguish between variation in a process resulting from common cause, and special cause. As a graphic display of the process stability or instability over time, it highlights statistical control limits, not specification or tolerance.

    Why using a Control Chart?
        • To make judgements of the process performance over a certain period of time
        • To assess the effectiveness of changes to improve a process

  • Corrective action
    It is the action taken to fix the cause of the nonconformity and to prevent recurrence.
