ware, software, and services. As with SDCI programs, the Business Case Development Phase is carried out under the leadership and direction of the PMT for the proposed program.

MILESTONE A:
PLANNING, ANALYSIS, AND CONCEPT DEMONSTRATION DECISION (CHSS PROGRAMS)

The purpose of the Milestone A: Planning, Analysis, and Concept Demonstration Decision Phase and the responsibilities of the PM, PMT and MDA for this category of IT acquisition programs are conceptually similar to those for SDCI programs. The difference at this decision milestone and in the subsequent program phase is that concept demonstration should be undertaken if and only if there are clear issues or questions that must be resolved through demonstration that cannot be resolved in successive capability increments. This will frequently not be the case for the use of unmodified COTS products or services. As such, concept demonstration should be regarded as optional, with a bias to not performing it for most programs. The principal focus should be on the planning and analysis activities. Due to the nature of CHSS programs, this will substantially be market research-based analysis with planning extended into the Deployment Phase.

INCREMENT 1 PLANNING, ANALYSIS, AND CONCEPT DEMONSTRATION PHASE (CHSS PROGRAMS)

The purpose of the Planning, Analysis, and Concept Demonstration Phase for CHSS programs is similar that for SDCI programs with the exception of the change in emphasis discussed above. Further, requirements will typically focus on capability, capacity, and key nonfunctional requirements (e.g., operational availability and environmental qualification for hardware).

As with the software development and COTS software integration category of IT programs, the Planning, Analysis, and Concept Demonstration Phase for the first increment can readily be adapted to a multiple-award contract model with a subsequent competitive selection of a single provider coincident with the initial Milestone B decision if such additional competition is deemed appropriate in the program’s acquisition strategy.

INCREMENT 2 AND BEYOND PLANNING AND ANALYSIS PHASES (CHSS PROGRAMS)

For subsequent planning and analysis phases after the initial one leading to the initial Milestone B Program Initiation Decision, the above
