Evolutionary acquisition is an acquisition approach that defines, develops, produces or acquires, and fields an initial hardware or software increment (or block) of operational capability based on technologies demonstrated in relevant environments, time-phased requirements, and demonstrated manufacturing or software deployment capabilities in a shorter period of time, followed by subsequent increments of capability over time that accommodate improved technology and allow for full and adaptable systems over time. This template is intended to assist the Program Manager and staff in the preparation of an acquisition strategy reflecting an evolutionary approach to systems development and acquisition.
