5.4 Level 4: Predictable process

The previously described Established process now operates within defined limits to achieve its process outcomes.

The following attributes of the process demonstrate the achievement of this level:

5.4.1 PA 4.1 Process measurement attribute

The process measurement attribute is a measure of the extent to which measurement results are used to ensure that performance of the process supports the achievement of relevant process performance objectives in support of defined business goals. As a result of full achievement of this attribute:

  1. process information needs in support of relevant business goals are established;

  2. process measurement objectives are derived from identified process information needs;

  3. quantitative objectives for process performance in support of relevant business goals are established;

  4. measures and frequency of measurement are identified and defined in line with process measurement objectives and quantitative objectives for process performance;

  5. results of measurement are collected, analyzed and reported in order to monitor the extent to which the quantitative objectives for process performance are met;

  6. measurement results are used to characterize process performance.

NOTE 1 Information needs may typically reflect management, technical, project, process or product needs.

NOTE 2 Measures may be either process measures or product measures or both.

5.4.2 PA 4.2 Process control attribute

 

The process control attribute is a measure of the extent to which the process is quantitatively managed to produce a process that is stable, capable, and predictable within defined limits. As a result of full achievement of this attribute:

  1. suitable analysis and control techniques where applicable, are determined and applied;

  2. control limits of variation are established for normal process performance;

  3. measurement data are analyzed for special causes of variation;

  4. corrective actions are taken to address special causes of variation;

  5. control limits are re-established (as necessary) following corrective action.
