Systems Engineering
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.
4. Requirements Types
4.3 Compliance
Performance and cost requirements are set by the project's customer with the help the engineering team. Compliance Requirements are set by external human rules such as laws, regulations, codes, and standards. Human rules often set minimum requirements in areas like safety. This does not prevent a system from adopting stricter levels. Human rules are usually designed to prevent undesirable effects. For example, speed limits on driving are intended to reduce the frequency and severity of accidents. Compliance requirements exist whether or not they are explicitly incorporated into the engineering process. It is better to incorporate them explicitly to avoid later problems. Other requirements are set by nature, such as the minimum altitude for a stable Earth orbit. These do not fall under compliance, but are accounted for elsewhere. In the case of altitude, this might be a performance requirement that a rocket deliver the payload to a 250 km high orbit.
