Operational Requirements Document

An Operational Requirements Document (ORD) was replaced by the Capability Development Document (CDD).  The ORD described the overall requirements for one system, how it interacts with other systems, and a systems performance goals.  An ORD is generally more detailed than a Concept of Operations (CONOPS). Older programs will have an ORD.  

The Mission Needs Statement (MNS) was replaced by the Initial Capabilities Document (ICD).
