Does zero projected open actions mean production can start?

No. The review authority must evaluate evidence, risks, resources and the applicable readiness criteria before authorizing the next step.

Can blocked actions be included in feasible closures?

No. The model excludes blocked actions from closures within this window. Resolve the blocker before moving the action into the unblocked group.

How should closure slots be estimated?

Use an action-specific resource and dependency plan. A historical average closure rate can mislead when the remaining actions are unusually difficult.

Why are severity scores no longer used?

The result now counts traceable work remaining. Severity and criticality still require program review, but multiplying ordinal ratings cannot establish readiness.

Production Readiness Action Gap Calculator

Estimate the readiness actions remaining at your next review. Enter the required action ledger, verified closures, blocked work and feasible closures before the review.

What this calculator does

Project open readiness actions at a review using verified closure evidence, blocked work and a feasible closure plan.

Formula used

Current open actions = required − verified closed
Unblocked actions = current open − blocked
Planned closures = min(unblocked actions, feasible closure slots)
Projected open actions = current open − planned closures

Inputs explained

Recorded Required Actions: Actions required by this program’s readiness review plan.
Verified Closed Actions: Actions with closure evidence accepted by the responsible authority.
Blocked Open Actions: Open actions that cannot close within the review window.
Feasible Closures Before Review: Unblocked actions the approved resource plan can close before review.

How to use the result

Best suited to readiness review Preparation, action closure planning.
An action count does not certify production readiness or flight safety. Actions have unequal effort and criticality despite equal counting. Legacy severity scenarios now vary recorded required action count.

Current U.S. benchmarks

Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).
