Metrics: Giving the Answer to the Right Question What metrics are you going to give me? This is the type of question managers ask their QA analysts at the start of each project. In this presentation, learn how to interpret data to create a metric that can answer a specific question asked by management. Explore how quality assurance and testing-from goal setting to implementing tactics-can assist in creating reliable metrics. Kenneth Paczas looks at many of the questions that have been asked by management--and the metrics that were used to answer them.

Using Statistics to Evaluate Process Improvement The techniques associated with Statistical Process Control (SPC) are very useful, but they are not sufficient alone to
provide inferential comparisons. An additional need is the ability to make valid
comparisons.
This paper suggests two additional techniques to help evaluate differences: inference for
difference between two means (using t tests and confidence intervals for the difference
between the means), and inference for two way tables (using chi-square tests). These basic
statistical techniques should be in our analysis toolbox, along with the traditional SPC tools.
