BaBok: 8.1 Measure Solution Performance --> 3 Collect Performance Measures. "When collecting performance measures, business analysts consider: • Volume or Sample Size: a volume or sample size appropriate for the initiative is selected. A sample size that is too small might skew the results and lead to inaccurate conclusions. Larger sample sizes may be more desirable, but may not be practical to obtain."

When measuring solution performance, Timing is crucial to ensure that the results accurately reflect the solution's effectiveness and are not skewed by seasonal, operational, or situational factors. According to BABOK Section 8.3: Measure Solution Performance, timing considerations involve ensuring that data is collected during appropriate periods to avoid anomalies that could affect the performance assessment. For example, measuring system performance during peak usage times versus off-peak times may yield very different results. Accurately timing the measurement helps ensure a reliable evaluation of the solution's effectiveness.
