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
4.14 Maintenance
These requirements include parameters like hours and costs to maintain the system in an operating state, probability of system failure, and levels of spares required. A system can fail without safety risk. For example, your car may not start, which is different than the brakes failing to operate. The more often that items fail to operate, the more spares are needed in stock, and the more time and money to repair or replace items. So the various maintenance requirements are linked. Maintenance requirements can be divided into preventive, which is before something stops working, and corrective, which is after.
