NPR 7150.2A, NASA PROCEDURAL REQUIREMENTS: SOFTWARE ENGINEERING REQUIREMENTS (19 NOV 2009)

NPR 7150.2A, NASA PROCEDURAL REQUIREMENTS: SOFTWARE ENGINEERING REQUIREMENTS (19 NOV 2009)., Software engineering is a core capability and a key enabling technology for NASA's missions and supporting infrastructure. This NASA Procedural Requirements (NPR) supports the implementation of the NASA Policy Directive (NPD) 7120.4, NASA Engineering and Program/Project Management Policy. This NPR provides the minimal set of requirements established by the Agency for software acquisition, development, maintenance, retirement, operations, and management. This NPR is intended to support NASA programs and projects to accomplish their planned goals (e.g., mission success, safety, schedule, and budget) while satisfying their specified requirements. This NPR provides a set of software engineering requirements in generic terms to be applied throughout NASA and its contractor community. For this NPR, Software Engineering is defined as the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software: that is, the application of engineering to software. For this NPR, Software is defined as the computer programs, procedures, scripts, rules, and associated documentation and data pertaining to the development and operation of a computer system. Software includes programs and data. This definition includes commercial-off-the-shelf (COTS) software, government-off-the-shelf (GOTS) software, modified-off-the-shelf (MOTS) software, reused software, auto generated code, embedded software, firmware, and open source software components.
