Purpose and scope

What this dashboard measures

Estimate the delivery delay caused by added work and contingency.

Baseline finish, Added work hours, Available team hours per day, Contingency percent, and Work parallelizable percent feed the component values beneath the Change-Request Schedule Impact Calculator headline; Carry Work parallelizable percent in its entered unit for comparison.

Instructions

How to use this calculator

Supply Baseline finish and Added work hours from the Change-Request Schedule Impact Calculator planning source, then carry Available team hours per day, Contingency percent, and Work parallelizable percent in their recorded units.

  1. Supply Baseline finish and Added work hours from one Change-Request Schedule Impact Calculator reporting period.
  2. Supply Available team hours per day, Contingency percent, and Work parallelizable percent without changing the Work parallelizable percent unit.
  3. Calculate the Change-Request Schedule Impact Calculator and match its headline with component values.
  4. Confirm the unit and convention for Work parallelizable percent before accepting the Change-Request Schedule Impact Calculator result.

Interpretation

Interpreting the headline metric

The estimate shows capacity impact and not whether the change actually enters the critical path.

Audit Baseline finish, Added work hours, and Available team hours per day beside the Change-Request Schedule Impact Calculator headline; Work parallelizable percent reveals rounding across the component values.

Calculation

Method used

Nonparallel added work is increased by contingency and divided by daily team capacity to estimate delay.

Delay days = added nonparallel hours × (1 + contingency) ÷ daily team capacity.

The Change-Request Schedule Impact Calculator evaluates Baseline finish, Added work hours, and Available team hours per day separately; carry Work parallelizable percent visible outside any percentage, rate, or total.

Calculation method last reviewed: June 21, 2026.

Worked scenario

Example calculation

Example: Eighty added hours with twenty-five percent parallel and twenty percent contingency create seventy-two scheduled serial hours.

Match Work parallelizable percent with the Change-Request Schedule Impact Calculator component values before judging the Work parallelizable percent headline scale or units.

Visual audit

Reading the supporting metrics

The Change-Request Schedule Impact Calculator dashboard places component values beside Baseline finish, Added work hours, Available team hours per day, Contingency percent, and Work parallelizable percent. Audit Work parallelizable percent in its original unit before accepting the component values or headline status.

Boundaries

Important edge cases and limitations

Critical-path placement, resource substitution, scope tradeoffs, and calendar exceptions require project analysis.

Adjust Work parallelizable percent in the Change-Request Schedule Impact Calculator before reading the component values or headline.

Input audit

Checklist for this calculation

  • Audit the Change-Request Schedule Impact Calculator period and Baseline finish and Added work hours units.
  • Match Work parallelizable percent with the Change-Request Schedule Impact Calculator component values.
  • Calculate a fresh Change-Request Schedule Impact Calculator after any Work parallelizable percent adjust.
  • Carry Available team hours per day, Contingency percent, and Work parallelizable percent beside the Change-Request Schedule Impact Calculator; include Work parallelizable percent in any saved or shared record.

Practical use

Recommended workflow

Map the request to affected dependencies and decide whether scope, date, or resources will absorb the impact.

Questions

Frequently asked questions

Why remove the parallelizable share?

Work completed alongside the baseline path may consume capacity without extending the final delivery date by its full duration.

Should a Work parallelizable percent update refresh the

A revised Work parallelizable percent makes the older Change-Request Schedule Impact Calculator stale unless Baseline finish uses the same planning source. Calculate a new Change-Request Schedule Impact Calculator output for the revised Work parallelizable percent case.

How should Baseline finish be recorded for the

Match Baseline finish with Work parallelizable percent inside the Change-Request Schedule Impact Calculator reporting basis. Carry the Work parallelizable percent unit aligned with the Baseline finish period before reading the headline.

How can Work parallelizable percent be sensitivity-tested in the

Carry Baseline finish and Added work hours unchanged and adjust Work parallelizable percent once in the Change-Request Schedule Impact Calculator. Match the Work parallelizable percent component with component values to identify a proportional or threshold effect.
