Systems Engineering is an interdisciplinary process that ensures that the customer's needs are satisfied throughout a system's entire life cycle. This process is comprised of the following seven functions:

   Stating the problem, which includes understanding customer needs,
       discovering system requirements and validating requirements;
   Investigating alternatives, which includes defining quantitative measures;
   Modeling the system, which includes functional decomposition, system design,
       sensitivity analyses, risk management, and reliability analysis;
   Integrating the system, which includes designing and managing interfaces;
   Launching the system, which includes configuration management,
       project management, documentation and leading teams;
   Assessing performance, which includes prescribing tests, conducting reviews,
       verifying requirements and total system test; and
   Re-evaluating and improving quality.
The purpose of Systems Engineering is to increase a system's probability of success, reduce risk, and reduce total-life-cycle cost. The Systems Engineering process can be applied to most projects, but it must be tailored for each.
