How to Cross Validate Surveys and Log Based Metrics
Using surveys and log-based metrics together can help in cross-validating data. Discrepancies between the two data types may arise due to incorrect log data or the omission of measuring underlying facets in surveys. For instance, log data including background robotic builds affected the perception of build latency among developers. Human perception and subjective experiences play a significant role, as observed in the psychophysics field. In software engineering, reducing build latency may not have a linear impact on productivity, as developers often shift to other tasks beyond a certain build duration. Understanding how humans react to changes in metrics is crucial for interpreting data accurately.
