key performance parameter
Performance attribute of a system considered critical or essential to the development of an effective military capability. KPPs are contained in the Capability Development Document (CDD) and the updated CDD and are included verbatim in the Acquisition Program Baseline (APB). KPPs are expressed in term of parameters which reflect Measures of Performance (MOPs) using a threshold/objective format. KPPs must be measurable, testable, and support efficient and effective Test and Evaluation (T&E). Mandatory KPPs are specified in the JCIDS Manual.
