Single Metrics Rarely Explain Complex Fatigue Patterns
Context
Analysis of correlations between individual performance metrics and observed fatigue patterns in development teams over extended periods.
Observation
Individual metrics showed maximum correlations of 0.43 with overall fatigue states, while combined metric sets achieved correlations up to 0.76. Single metrics often produced false positives or missed significant fatigue indicators.
Insight
Fatigue patterns appear to manifest through complex interactions of multiple indicators rather than through clear individual signals. The relationship between any single metric and overall fatigue state shows significant variability.
Why This Matters
Reliance on individual metrics for fatigue assessment may provide incomplete or misleading information. The multi-dimensional nature of fatigue patterns suggests the need for more nuanced measurement approaches.
Limitation
Study focused on commonly tracked development metrics. Other individual indicators not typically measured in development environments might show stronger correlations.
