One of the principle goals of enterprise systems is to set and meet their performance objectives. With each passing day, organizations become impacted because of performance issues due to a direct loss in revenue and brand reputation risks. Performance engineering starts where performance testing stops. Performance engineers, after test execution, deep dive using analytic tools aimed at identifying performance bottlenecks. They provide solutions to resolve the identified issues. Organizations want a system that not only meets their business outcome, but one which does not compromise on performance parameters. Thus, the technical parameters should always be in conjunction with non-functional parameters, such as scalability, workload endurance, flexibility, maintainability, security, reliability and usability. This paper will describe the needs and role of Performance Engineering in Enterprise Systems to achieve all of the above goals to improve cost-effectiveness and reduce risk-based productivity with its application in Automated Teller Machines (ATMs).
