Completion requirements
System engineering can best be explained as coordinating multiple tasks within the two disciplines of engineering and engineering management. This paper highlights the systems method of coordinated tasks and its relevance concerning current and future business system life cycles: concept, design, planning, testing, optimization, and deployment. It defines the boundaries necessary for a robust life cycle and analysis to occur.
