Purpose and scope

What this dashboard measures

Use historical cycle times to forecast completion at a selected percentile.

Historical cycle times days, Forecast percentile, Items remaining, and Average parallel items feed the breakdown values beneath the Agile Cycle-Time Percentile Forecaster headline; Maintain Average parallel items in its entered unit for comparison.

Instructions

How to use this calculator

Choose Historical cycle times days and Forecast percentile from the Agile Cycle-Time Percentile Forecaster recorded basis, then maintain Items remaining and Average parallel items in their recorded units.

  1. Choose Historical cycle times days and Forecast percentile from one Agile Cycle-Time Percentile Forecaster reporting period.
  2. Choose Items remaining and Average parallel items without changing the Average parallel items unit.
  3. Derive the Agile Cycle-Time Percentile Forecaster and test its headline with breakdown values.

Interpretation

Interpreting the headline metric

A higher percentile is more conservative but still assumes future items resemble the historical sample.

Scan Historical cycle times days, Forecast percentile, and Items remaining beside the Agile Cycle-Time Percentile Forecaster headline; Average parallel items reveals rounding across the breakdown values.

Calculation

Method used

The selected empirical percentile is multiplied by the number of serial item waves.

Forecast days = empirical cycle-time percentile × ceiling(remaining items ÷ parallel items).

The Agile Cycle-Time Percentile Forecaster evaluates Historical cycle times days, Forecast percentile, and Items remaining separately; maintain Average parallel items visible outside any percentage, rate, or total.

Calculation method last reviewed: June 21, 2026.

Worked scenario

Example calculation

Example: Twelve remaining items with three in parallel require four waves; an eight-day percentile produces a thirty-two-day forecast.

Test Average parallel items with the Agile Cycle-Time Percentile Forecaster breakdown values before judging the Average parallel items headline scale or units.

Visual audit

Reading the supporting metrics

The Agile Cycle-Time Percentile Forecaster dashboard places breakdown values beside Historical cycle times days, Forecast percentile, Items remaining, and Average parallel items. Scan Average parallel items in its original unit before accepting the breakdown values or headline status.

Boundaries

Important edge cases and limitations

Historical items must resemble future work; dependencies, blocked time, and changing WIP can invalidate the forecast.

Modify Average parallel items in the Agile Cycle-Time Percentile Forecaster before reading the breakdown values or headline.

Input audit

Checklist for this calculation

  • Scan the Agile Cycle-Time Percentile Forecaster period and Historical cycle times days and Forecast percentile units.
  • Test Average parallel items with the Agile Cycle-Time Percentile Forecaster breakdown values.
  • Derive a fresh Agile Cycle-Time Percentile Forecaster after any Average parallel items modify.

Practical use

Recommended workflow

Remove incomparable outliers only with a documented reason and refresh the sample as workflow changes.

Questions

Frequently asked questions

What does an eighty-fifth-percentile cycle time mean?

Approximately eighty-five percent of the historical observations completed at or below that duration.

When is a previous agile cycle-time percentile forecaster output no longer comparable?

Another Agile Cycle-Time Percentile Forecaster run is warranted when Historical cycle times days moves, Average parallel items is redefined, or the governing calculation rule changes.

Which convention should Historical cycle times days use in the

Test Historical cycle times days with Average parallel items inside the Agile Cycle-Time Percentile Forecaster reporting basis. Maintain the Average parallel items unit aligned with the Historical cycle times days period before reading the headline.
