An Investigation of the Reliability of the Contractor Performance Assessment Reporting System (CPARS).

Abstract

An Industry trend is to establish long-term relationships with reliable suppliers. One of the criteria used to pick these "reliable suppliers" is past performance. The Department of Defense is also attempting to capitalize on this logical trend to the maximum extent possible by using past performance as an evaluation factor in source selections. Air Force Material Command (AFMC) employs the Contractor Performance Assessment Reporting System (CPARS). This thesis examines the reliability of the CPARS. This thesis found, despite the fact that policy mandates color ratings be based on period objective measures, the cost color ratings were more consistent with cumulative objective measures. Even so, the strength of this relationship has degraded significantly over time. With respect to schedule, the reliability is improving significantly, but period objective measures are not yet significantly correlated with schedule color ratings. The author recommends that AFMC either change CPARS cost rating policy to reflect the use of cumulative objective measures or provide additional training so evaluators better understand what is assessed during a CPARS rating period.
