S13-303/403: Buried in the Numbers: Interpreting Performance Test Results, and Planning For Them (Part 1 and 2)

Track: Performance Testing

Operating a scripting/playback tool is only one step in performance testing. Real value is added by analyzing and interpreting the barrels of numbers collected during a test. Adding analysis to data produces information. Interpreting this information skillfully yields hypotheses to test, conclusions to draw and results you can act on. These are the real value of the performance test and of the tester. Generating these results requires insightful advance planning and test design—the critical business-analyst challenging aspect of performance testing.

In this two part session we will start with results: what they mean, and where they come from. As we focus on identifying patterns in results that indicate information we are testing for, we will describe how to generate, collect, correlate, and interpret actionable information before and during performance tests.

We’ll also share with you an approach to reporting results in a clear and compelling manner, with data-supported observations, conclusions drawn from these observations, and actionable recommendations.

From feedback on earlier versions of this presentation-workshop, I feel certain that you will take home at least one new idea that will make you a more effective performance tester. Come prepared to participate actively!
