Diagnosing phase
In the Diagnosing phase, a more complete understanding of improvement
activities is developed. This phase establishes the basis for the work performed
in later phases. The process as currently practiced is captured and documented.
This current process is then compared to some process model, such
as the CMM ® , and gaps between the model and actual practices are identified.
Typically, an assessment is used for that purpose, but other forms of gap
analysis can be equally effective. These gaps then serve as a basis for process
improvement and, in turn, development of the new and improved process.
Establishing phase
In the Establishing phase, a detailed process improvement plan is developed,
based on organizational goals and objectives and the gaps identified in the
previous phase. Priorities for the improvement efforts and project performance
goals are determined; process improvement activities usually require
the same resources needed for project activities. Diverting people to a process
improvement initiative may impact product delivery schedules. The framework
set up in the initiating phase should be able to mitigate those conflicts.
The goals and objectives and the gaps identified in the diagnosing phase
define the scope of the process improvement activities. A detailed process
