(a)
Down-selection. In a phased procurement, the process of selecting contractors for phases subsequent to the initial phase from among the preceding phase contractors.(b)
Major system. Any system that: Is directed at and critical to fulfilling an agency mission; entails the allocation of a relatively large amount of resources; or warrants special management attention. Designation of a system as “major” is made in accordance with NMI 7120.4, “Management of Major System Programs and Projects,” and NHB 7120.5, “Management of Major System Programs and Projects Handbook.”(c)
Phased procurement. A program comprised of several distinct steps or phases (e.g., preliminary analysis, definition, design, and development) where the realization of program objectives requires a planned, sequential acquisition of each step or phase. The phases in a phased procurement may be acquired separately, in combination, or through a down-selection strategy.(d)
Progressive competition. A type of down-selection strategy for a phased procurement. In this method, a single solicitation is issued for all phases of the program. The initial phase contracts are awarded, and the contractors for subsequent phases are expected to be chosen through a down-selection from among the preceding phase contractors. In each phase, progressively fewer contracts are awarded until a single contractor is chosen for the final phase. Normally, all down-selections are accomplished without issuance of a new, formal solicitation.
