Types of Processes

  • The systems engineering process can be decomposed into:
    • A Systems Engineering Technical Process: assessing available information, defining effectiveness measures, and creating a behavior model.
    • A Systems Engineering Management Process: organizing the technical effort in the lifecycle.

Systems Classification

  • Natural Systems vs Man-Made Systems:
    • Natural systems have defined laws and are self-organized.
    • Man-made systems are made by humans and can be divided into Engineered Systems and Non-engineered Human Systems.
  • Static Systems vs Dynamic Systems:
    • Static systems do not change their state within a specified system life cycle.
    • Dynamic systems change their state over time.
  • Conceptual Systems vs Physical Systems:
    • Conceptual systems consist only of concepts and are used to analyze the feasibility of a system.
    • Physical systems consist of objects that can be seen, touched, and felt.
  • Open Systems vs Closed Systems:
    • Open systems exchange information, matter, or energy with their surrounding environments.
    • Closed systems do not exchange things with their surrounding environments.

Interdisciplinary Effort
