Complexity Chart Anomaly

Estimation

Default severity: medium
EstimationMetricsQualityEffort

What it detects

Max time within a story point size class exceeds the min by more than the configured factor — the point size is not calibrated to actual effort.

Detection formula

IF (max_time\[sp_class\] / min_time\[sp_class\]) > config.estimation.complexity_spread_factor // default: 20x THEN FLAG for that sp_class Report per sp_class: min, max, median, spread_ratio

Examples in practice

  • Estimates, time logged, and actual effort no longer align for a meaningful share of items.
  • The team commits to sizes that are not supported by historical spend patterns.
  • A team shows max time within a story point size class exceeds the min by more than the configured factor while complexity spread factor is set to 20x.

Suggested response

Align estimation and logging practices so size, time spent, and scope changes remain comparable.

Coaching playbook

Symptom

Max time within a story point size class exceeds the min by more than the configured factor — the point size is not calibrated to actual effort.

Why it matters

When "Complexity Chart Anomaly" keeps appearing, the team is signalling a repeatable process gap. Left unexamined, the pattern hides where work really stalls and makes improvement metrics harder to trust.

What you can achieve

Align estimation and logging practices so size, time spent, and scope changes remain comparable.

Facilitation questions

  • What system change would stop "Complexity Chart Anomaly" from firing again?
  • What do the cited issues have in common — same root cause or same workaround?
  • Who owns the two-week experiment and how will we verify on the next import?
