SYSTEMS ENGINEERING HANDBOOK
|Publication Date:||9 November 2018|
This Handbook describes the basic processes and provides general guidance for managing and implementing systems engineering throughout the life-cycle for all programs/projects/ac
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.
