CMMI Question:

PII is acronym for Practice Implementation Indicators. They are pieces of evidence that a particular CMMI practice will leave evidence that it has been performed. It could be a document, a spreadsheet, or any artifact. The appraiser looks for PII for assessment. There are 3 types of PII:

Direct artifacts: tangible outputs resulting from implementation of a process or practice.

Indirect artifacts: Artifacts that are results of performing a specific practice that substantiate its implementation.

Affirmations: Oral or written statements of a specific practice. They are often provided by the implementers of the practice or other stakeholders.
