Expanded Guidance for NASA Systems Engineering: Volume 1: Systems Engineering Practices (March 2016) NASA/SP-2016-6105-SUPPL

Since the initial writing of NASA/SP-6105 in 1995 and the following revision (Rev 1) in 2007, systems engineering as a discipline at the National Aeronautics and Space Administration (NASA) has undergone rapid and continued evolution. Changes include implementing standards in the International Organization for Standardization (ISO) 9000, using Model-Based Systems Engineering to improve development and delivery of products, and accommodating updates to NASA Procedural Requirements (NPR) 7123.1. Lessons learned on systems engineering were documented in reports such as those by the NASA Integrated Action Team (NIAT), the Columbia Accident Investigation Board (CAIB), and the follow-on Diaz Report. Other lessons learned were garnered from the robotic missions such as Genesis and the Mars Reconnaissance Orbiter as well as from mishaps from ground operations and the commercial spaceflight industry. Out of these reports came the NASA Office of the Chief Engineer (OCE) initiative to improve the overall Agency systems engineering infrastructure and capability for the efficient and effective engineering of NASA systems, to produce quality products, and to achieve mission success.In 1995, SP-6105 was initially published to bring the fundamental concepts and techniques of systems engineering to NASA personnel in a way that recognized the nature of NASA systems and the NASA environment. In 2007, Rev 1 of the handbook was finalized and distributed. While updating the 2007 rev 1 version of the NASA Systems Engineering Handbook for a new Rev 2 version, authors from across the Agency submitted a wealth of information that not only expanded on the content of the earlier version but also added entire new sections. This body of knowledge has been captured in this document as “Expanded Guidance for NASA System Engineering,” presented in a two-volume set. The over 700 pages of information is considered a relevant reference to the larger NASA Systems Engineering community of practitioners.The official second revision of the NASA Systems Engineering Handbook filters some of this information that is ancillary to implementing NPR 7123.1 for the purpose of condensing the information into a more manageable version useable as a handbook. The official revised NASA Systems Engineering Handbook is a more focused “core” version of the information in this expanded guidance document.This expanded guidance continues the methodology of the SE Handbook: a top-down compatibility with higher level Agency policy and a bottom-up infusion of guidance from the NASA practitioners in the field. This approach provides the opportunity to obtain best practices from across NASA and bridge the information to the established NASA systems engineering processes and to communicate principles of good practice as well as alternative approaches rather than specify a particular way to accomplish a task. The result embodied in this handbook is a top-level implementation approach on the practice of sys Read more
