System efficiency/merit (a total system evaluation)

System Efficiency/Merit is a complete evaluation as to how well a system is designed with regard to performance, design adequacy, reliability, human factors, survivability, and cost effective production and maintenance. System efficiency/merit (a total system evaluation) can be defined as the assessment of all the system parameters that contribute to how well the system is designed for a successful, cost effective operation. The main ingredients of system efficiency are: system effectiveness and cost. Therefore maximum system efficiency is obtained only if the system is optimized in all parameters that influence capability, either from the performance aspect or the operational aspect. The various factors not only cannot be ignored but also must be evaluated continuously for improvements and innovations from the beginning of the design phase to the end of the production phase. Weak links must be identified and singled out for upgrading to achieve the highest possible system efficiency.
