Mission Need Statement

Within the context of the U.S. Department of Defense, a Mission Needs Statement was a type of document which identified capability needs for a program to satisfy by a combination of solutions to resolve a mission deficiency or to enhance operational capability.
This term was introduced as a fundamental step in CJCSI 3170.01B, 6212.01D, and the Interim Defense Acquisition Guidebook.
This type of document has been superseded by the description of capability needs called an Initial Capabilities Document, as of CJCSI 3170.01E. The CJCSI 3170.01 and 6212.01 were superseded by the CJCSI 5123.01 Series.
