capability development document
A CDD (includes the Information System (IS) CDD variant) specifies capability requirements in terms of developmental Key Performance Parameters (KPPs), Key System Attributes (KSAs), Additional Performance Attributes (APAs), and other related information necessary to support development of one or more increments of a materiel capability solution. A sponsor approved draft CDD is necessary for a Milestone A acquisition decision and each RFP release in support of the Technology Maturation and Risk Reduction (TMRR) phase of the Defense Acquisition System. A validated CDD is also necessary for each Development Request for Proposal (RFP) Release Decision Point and Milestone B acquisition decision. The CDD format is in the Joint Capabilities Integration and Development System (JCIDS) Manual, which is available online.
