Evaluating ResultsEvaluating Results
• Numerous metrics available
• Understand capabilities & limitations of each metric
• Remember large number of variables and scenarios encompassed
• Focus in on key performance characteristics and on thresholds of performance
• Understand the expected range of variation in “typical” use
• Assess general performance envelope
