When creating system performance models, the primary challenges are where and how to start. Whatever the performance characteristics being estimated or modeled, we need a solid approach that addresses both business and system needs. All too often performance tests inadvertently mix load and stress scenarios with little regard for how this will confound recommendations and business decisions. If you are a test manager, a business process owner, or you simply want to better understand performance testing, you will be interested in Will’s case study. Will presents a real-world example that demonstrates the impact on business decisions and shows how to use production data and statistical modeling to improve both the analysis and business decisions. The study is based on a back-end re-hosting project where acceptance criteria were based on an achieving “equal or faster” performance. Take away new insights and approaches to improve performance-based decisions for your organization.
