Testing and Modelling: A Two-pronged Approach to Risk Mitigation

摘要

Performance testing and modelling have long been used to reduce the risk of poor performance impacting business services, but often in isolation. This paper discusses the relative merits and weaknesses of each approach, and the tools, people and processes required to deliver them. This paper considers the importance of combining the strengths of each approach to provide best-practice performance assurance. In particular it focuses on how Capacitas has integrated testing and modelling processes in order to provide cost-effective risk mitigation for the easyJet.com service.
