17 Process Capability Levels Optimizing The process is continuously improved to meet relevant current and projected business goals Predictable The process is enacted consistently within defined limits Level 5 Optimizing process PA 5.1 Process innovation attribute PA 5.2 Process optimization attribute Level 4 Predictable process PA 4.1 Process measurement attribute PA 4.2 Process control attribute Established A defined process is used based on a standard process Level 3 Established process PA 3.1 Process definition attribute PA 3.2 Process deployment attribute Level 1 Performed process PA 1.1 Level 2 Managed process PA 2.1 PA 2.2 Performance management attribute Work product management attribute Process performance attribute Performed The process is implemented and achieves its process purpose Managed The process is managed and work products are established, controlled and maintained Level 0 Incomplete process Incomplete The process is not implemented or fails to achieve its purpose 17 Jacqueline Johnson 06/04/2012

18 Process Attributes- Level 1 PA 1.1 Process performance extent to which the process purpose is achieved. full achievement means that the process achieves its defined outcomes. 18 Jacqueline Johnson 06/04/2012
