Many graduates of formal educational programs do not enter the work force ready to approach or solve the complex problems faced by Systems Engineers (SE). This book describes the processes and practices commonly employed for Systems Engineering which provide a greater depth of understanding for Systems Engineers and Systems Engineering Managers. Earlier chapters present an overview of the Systems Engineering Processes; the Technical processes, Project processes, and Organizational (Enterprise) processes; Life-Cycle Stages; Enabling Systems Engineering processes; Systems Engineering Support Activities; Specialty Engineering Activities; and SE processes Tailoring. Later chapters describe the Systems Engineering Processes and Practice including Standard SE processes; the Stakeholder Requirements Definition Process; the Requirements Definition Process; the Logical Decomposition Process and Functional Analysis and Allocation; the Systems Architecture Process; and the Trade Study Process.
