NASA Systems Engineering Handbook MSFC Technical Standard: MSFC-HDBK-3173 Revision C

ScopeThis Handbook describes the basic processes and provides general guidance for managing and implementing systems engineering throughout the life-cycle for all programs/projects/activities (PPA) managed at Marshall Space Flight Center (MSFC) and executing the systems engineering processes employed at MSFC.Its intended use is for PPAs that provide aerospace products, technologies, data, and operational services (aeronautics, space, and ground). It also serves as an information source for PPA such as non-flight infrastructure, Construction of Facilities (CofF), Small Business Innovation Research (SBIR), and for research and analysis PPAs.The guidance contained in this document, while not required, documents proven best practices and approaches to systems engineering and is aligned with the NASA and MSFC policies and guidance for Systems Engineering.Systems engineering principles and practices described in this Handbook apply to MSFC PPAs. Nevertheless, the emphasis of the document is to describe the systems engineering processes necessary for PPA development; therefore, in general, the document refers only to systems engineering.While all process activities and general guidance are addressed, PPA managers, working with their systems engineers (SEs), and Chief Engineer (CE) may tailor and customize implementation to the specific needs of the PPA consistent with PPA size, complexity, criticality and risk.Tailoring and customizing are mechanisms to encourage innovation and achieve products in an efficient manner while meeting the expectations of the customer. Tailoring results when a requirement is removed or modified from a PPA, whereas, customization results when a best practice or guidance is removed or modified from the PPA (MRP 7120.1).Results of the tailoring will be documented in Program Commitment Agreements (PCAs), Program Plans, Project Plans, and Activity Plans. All PPAs comply with applicable MSFC directives, requirements established by law, regulations, Executive Orders, and Agency directives.1.2 PurposeThe purpose of this Handbook is to describe the basic systems engineering principles and processes and to provide general guidance for implementing these systems engineering to PPA at the MSFC.This Handbook also defines the contemporary policies and practices employed at MSFC in the planning and execution of systems engineering processes.This document is not intended to be a specification for future PPAs, but is to be used as guidance in both in the management of PPAs and in the development of plans for future PPAs.It will also serve as an orientation for newcomers and outsiders to the MSFC processes in the systems engineering employed in the development of space systems.
