AI.07 Capability Control Action in Progress Context

If a KPI review determines that a process is stable but incapable of meeting the required specifications, it must be determined if there are any current analyse and Improve activities that will improve the process capability. If there are no activities in place to improve capability then the issue should be referred for further investigation. If activities are in place to address the capability issue then implementation of these should continue. Purpose To decide if a new capability issue investigation should be initiated. Quantity One decision whether there is a current Analyse and Improve activity that will improve the process capability. Quality Review current active issues to identify any intended to improve the capability of the process. Resources This task is completed by the manager responsible for the process. Time Process capability will only change after there is either an indicated change in process stability or the process specifications are changed. Therefore the minimum requirement is to review capability after;  a change in process stability, and  the process performance has reached a stable state, and  there are sufficient data points to make a reasonable judgement (hopefully 25 but certainly more than 7), or  there is a change to the process specifications.
