Today's systems and their applications incorporate a variety of complex, physical, logical, and human elements. The interactions between these elements are often so complex that intuition alone is not sufficient for estimating the performance indices of interest. These systems, under a tremendous heavy workload, are expected to generate high throughput at a reasonable level of resources' utilization , fast response time , and maintain high level of quality (such as availability, reliability, and maintainability ). These challenging technical performance specifications have imposed on the applications of interest numerous critical technical problems throughout their entire acquisition lifecycles. This paper defines, introduces and addresses a comprehensive systematic performance process to quantify and analyze these technical problems. This performance process identifies and organizes the system performance measurements; structures and addresses its major steps throughout the entire system acquisition lifecycle. Proper implementation of this performance process will ensure on time delivery of high quality and low cost systems.
