While the SEI has not published specific guidelines for institutionalization,
a number of appraisers consider a minimum of six months as a demonstration
of basic institutionalization. Other appraisers expect to see that practices have
been performed through several cycles. And some other appraisers have considered
the requirement to be a demonstration that the practices have been
performed in the past and will continue after the appraisal. In addition, some
Lead Appraisers consider how often a process can be performed. For example,
on a 20-year-old legacy system, they would not consider it reasonable to
expect that the initial customer requirements were captured using today??™s
process; however, they would expect new requirement changes to use today??™s
process. With no stated institutionalization requirement, a Lead Appraiser
and Appraisal Team may consider any or all of the above guidelines.
13. How do Lead Appraisers interpret the need for documented procedures in
the CMMI, now that the phase ???according to a documented procedure??? is
not used? Are documented procedures required, or can an acceptable alternative
practice be to perform the practice without a documented procedure?
Explain in terms of both organization-level and project-level procedures.
