Introduction The purpose of this plan is to define the implementation of the Marshall Space Flight Center (MSFC) software development process improvement effort and to document MSFC support of

15、the National Aeronautics and Space Administration (NASA) Software Engineering Initiative Implementation Plan. In compliance with the NASA Engineering and Program/Project Management Policy NPD 7120.4, a major benefit that MSFC derives from the implementation of this initiative is improved software de

16、velopment and acquisition processes enabling MSFC to develop and acquire higher quality software. A major focus of this effort is to improve the processes and practices in use at MSFC by continually measuring the level of process maturity against the Software Engineering Institutes Capability Maturi

17、ty Model-Integration (CMMI) for development. In accordance with MWI 7120.4, this document adheres to the mandatory template for a MSFC Technical Standard document. Sections 1 through 3 of the center plan required content as defined in Appendix C of the NASA Software Engineering Initiative Implementa

18、tion Plan are addressed in Section 1.1, Section 1.2, and Section 1.3 of this plan, respectively. 1.2. Goal The goal of the NASA Software Engineering Initiative Implementation Plan is to “advance software engineering practices to effectively meet the scientific and technological objectives of NASA.”

19、The goal of the MSFC Software Engineering Improvement Plan is to improve the quality of software produced by MSFC, in terms of planning, implementation, testing, and support. These goals are realized by addressing the following areas: a. Improvement in software engineering processes across MSFC. b.

20、Improvement in software acquisition processes on MSFC contracts. c. Collection and use of software metrics in the management of software development projects. d. Professional development for the MSFC software engineers. e. Research in software process and product improvement techniques and methods.

21、1.2.1. Rationale for Implementing this Plan The highest priority of this plan is to improve NASAs capability to deliver safe, reliable, quality software that meets system and software requirements.
