2.4 Summary
The authors of SCAMPI have worked to balance the cost and rigor of the method. SCAMPI was developed from the CMM for Software's CBA-IPI method and the SECM method; one very rigorous and one very cost effective. This balance of cost and rigor has been accomplished (in part) by basing the SCAMPI appraisal method on verification of data rather than on discovery. One consequence of this is that the organization is responsible for presenting a large amount of data to the appraisal team for them to verify. A vehicle to communicate how the data from the organization being appraised relates to the model is the Practice Implementation Indicator Description (PIID). PIIDs and the Class A SCAMPI method are discussed in the next chapter.
