There are direct and indirect artifacts used to provide evidence that helps prove
practice implementation. Direct artifacts are basically the expected or direct outcome
from implementing the practice. For instance, Project Planning has a specific
practice that reads, ???Establish and maintain the overall project plan.??? The direct
evidence listed in the PIID for Project Planning would be the overall project plan.
That makes sense. Wouldn??™t you expect the direct output of planning a project to
be a project plan? Also included as direct evidence is the revision history of the plan.
This artifact may not seem as direct as the plan. The revision history shows that
the plan has actually been used, and maps to the phrase ???Establish and maintain???
in the practice. (Remember, the phrase ???Establish and maintain??? means to create
and use what has been created.) The indirect artifact example is listed as ???issues
and conflicts identified across subordinate plans.??? The basis of these artifacts comes
from the Typical Work Products displayed under each practice within each process
324 n Interpreting the CMMI
area.
