41、ments; system level testing; managing and planning for BDSS. f. Direct communication between the using community and the SSA is important to help identify and isolate software problems, and to foster attitudes of support and cooperation. 4.4 Evolution of software suport. Software support, and hence

42、the role of the SSA, evolves as acquisition progresses. The SSAs capability to conduct PDCS and the eventual cost of PDSS closely depend on what occurs, or what fails to occur, during the pro-deployment stage. In general, during the pro-deployment software support stage the focus of software support

43、 should be to ensure software supportability and to plan for cost effective PDSS. During the PDSS stage, the focus of software support should be to ensure continued supportability, to manage PDSS, and to conduct efficient PDSS operations. - 4.4.1 Software sumort and the acquisition procesfi. In aoco

44、rdanae with DoD Directive 5000.1, the acquisition process is divisd into five phases: concept exploration/definition; concept demonctration/validation; full-scale development; full-rate production and initial deployment; and operations support. The chronological relationship between the acquisition

45、process and the evolution of software support can vary. Figure 1 identifies typical ILS and software support activities within the context of the acquisition process. Early in the acquisition process, program direction defines the responsibilities of the Program Manager and other acquisition partici
