Specifying Initial Design Review (IDR) and Final Design Review (FDR) Criteria

Many Department of Defense DoD development programs, such as aircraft development programs, are typically complex and long-lived. Often, these programs are structured to demonstrate significant capability in the form of prototypes, which may be additionally intended to provide lingering operational capability. As such, technology development activities frequently include design reviews known as the Initial Design Review IDR and the Final Design Review FDR that are not present in most other systems acquisitions. IDR and FDR content is not explicitly defined in regulations or policies rather, it is defined by the program office. However, since IDR and FDR are the Technology Development phases equivalent to Preliminary Design Review and Critical Design Review, this technical note proposes that they should have similar criteria, scaled for Technology Development work. This technical note presents definitions of IDR and FDR, their context in the acquisition life cycle, a comparison of engineering emphasis during IDR and FDR, IDR and FDR pre- and postconditions, and IDR and FDR criteria and how to apply them. The audiences for this technical note are managers and developers of medium to large DoD systems that employ technology that is not mature enough to transition directly to systems development.
