Web Application Performance Requirements Deriving Methodology

Abstract

This Master’s Study evaluates the possibilities of improving the existing service model within a shared service of the case company. It proposes the new methodology and a series of supporting documentation to improve the existing process of performance requirement gathering. The main goal of this study is to find the possible way(s) to improve the quality of the followed requirement gathering process in the case department of the case company. Secondly, to provide the supporting documentation for performance engineers of the department to help them in deriving the effective performance requirements well as design effective workload models. As an outcome of the study, a new method to gather requirements and further derive the test types is proposed. The new methodology implemented during study in a case project, shows improvement in the quality of the gathered requirements and hence in quality of the performance test results. The proposed methodology helps management to understand the benefits of the new method and a possible way to improve the area that was lagging earlier. The small improvement in the requirement gathering stage leads to major gains in the later stages of the performance testing and better prediction of the production performance.
