The FAA system engineering process applies both technical and management principles in a manner that:

• Results in a responsive system design from an operational need and benefit through the use of a structured, iterative process.
• Integrates the contributions of both traditional engineering and specialty disciplines to meet all cost, technical, quality and schedule objectives.
• Provides a product that satisfies users and other stakeholders.

The System Engineering Manual (SEM) is designed as a how-to manual or guide to SE and defines the 13 constituent SE elements to be performed throughout the program lifecycle. The SEM describes the key process activities that are necessary to effectively implement SE principles. The manual offers what-to-do and how-to-do-it information for all of the SE elements. Individual programs tailor the application of processes, tools, and techniques, according to program requirements.

The FAA Commercial Off-the-Shelf (COTS) Risk Mitigation Guide supports the Risk Management element described in SEM Chapter 4.10. It describes the risks that are associated with a COTS-based acquisition and identifies proven risk mitigation strategies and activities in a practical what, when, why and how manner. Included in the guide are processes and tools designed to assist programs to analyze, project and manage COTS product obsolescence issues before they affect system/service operations.
