A.I.R.O.N. A3 Problem Solving Managed Flow

A3 Problem Solving

Use A3 when the plant needs one disciplined story: background, current condition, target, root cause, countermeasure, follow-up, and proof.

Managed flow

Keep the problem story on one governed sheet.

A3 prevents loose notes from becoming loose action. The page walks the team from background through follow-up and retained standard work.

1. Background

Why does this problem matter now? Tie the issue to customer, safety, production, maintenance, compliance, or quality impact.

Event workspace

Build the A3 package.

Capture the A3 story, liability reduction, savings/efficiency impact, sustainment routine, evidence package, V.A.U.L.T. lanes, and KPI preview in one local managed-flow record.

Stage the proof package before V.A.U.L.T. retention.

Use references, filenames, work order numbers, photo notes, and document links for now. This does not upload files yet; it prepares the evidence path so the final V.A.U.L.T. handoff is not scattered.
