process models, are available. Common to all assessment methods
is their ability to identify process improvement opportunities.
Although the repeatability of assessment results may vary with the
method’s formality, even the most informal methods provide results
that can be used for establishing a process improvement road map.
4. Analyze assessment output and derive an action plan. Upon analyzing
assessment recommendations, the assessed organization develops
detailed process improvement plans. Strategic plans respond to strategic
business goals and priorities, whereas tactical plans outline
detailed process improvement steps for implementing improvements
that satisfy the strategic objectives.
5. Implement improvements. A process improvement infrastructure
enables development of new processes and transfer of those processes
to projects. Typically, a process engineering group (PEG) is formed
to lead this effort. The PEG analyzes assessment results and finetunes
the process improvement plan. Once the course of action is
determined, the PEG will spawn process action teams (PATs) responsible
for researching and implementing specific process improvement
activities.
