System Development Life-cycle diagram

systems engineering – a field of engineering that deals with complex engineering projects which should be designed and managed over the life cycle of the project. Systems engineering deals with work-processes and tools to handle projects. It applies both technical and human-centered disciplines such as control engineering, industrial engineering, organizational studies, and project management.

  • logistics
  • coordination of different teams
  • automatic control of machinery

system life cycle usually has seven phases. However, the system life cycle is different for different industries, products and customers.

  • discovering system requirements,
  • investigating alternatives
  • full-scale engineering design
  • implementation
  • integration and test
  • operation, maintenance and evaluation
  • retirement, disposal and replacement.

  • Survey of Systems Engineering – the value and purpose of systems engineering, the systems engineering project life cycle, and relate the roles of systems engineers in complex space missions. You will also identify the roles and concepts of operations, requirements, and trade studies in the project lifecycle and demonstrate the ability to apply these concepts to a real NASA mission.
