A3 Problem-Solving Template with Coaching Prompts

Use this A3 to tell a concise problem-solving story

The A3 helps teams move from observed problem to durable countermeasures using a single-sheet narrative. Work with your team to draft each section, use the coaching prompts to guide handoffs between frontline and leader, and save the A3 for review and learning.

Quick tips

  • Focus on observable facts and measurements, not opinions.
  • Timebox the first draft (30–90 minutes) then test countermeasures quickly.
  • Leaders should ask coaching prompts to improve clarity and follow-through, not to take over the work.

Short example (filled A3 snapshot)

Background: Manual orientation of part X sometimes reversed, causing assembly rework and 4% scrap on Line 2.

Current condition: 12 defects per 3000 parts (0.4%) this month; root cause traced to ambiguous visual cue and similar tooling.

Goal: Reduce orientation defects to <0.05% within 30 days.

Analysis / Root cause: Visual cue (sticker) worn; operator steps unclear; fixturing allows two orientations.

Countermeasures: Add poka-yoke fixture, refresh work instruction with photo, 1-hour operator coaching.

Implementation plan: Fixture ready in 7 days, pilot on one shift, measure defects, scale if effective.

Follow-up: Check daily defect log for 14 days, then weekly for 90 days.

Give the A3 a concise name that your team and leaders will recognize (e.g., 'Part X orientation defects - Line 2').
Brief context: customer impact, volume affected, safety/quality/cost implications. Keep it focused on why the team should solve this now.
Describe measurable facts: what is happening, where, when, how often. Include numbers, charts, photos, or references to logs if available.
State the target you want to achieve and a timeframe (e.g., reduce defect rate from 0.4% to &lt;0.05% within 30 days).
Summarize key observations and data. Use simple tools (5 Whys, Pareto, process mapping) and link to the main evidence that led you toward the root cause.
List suspected root causes. Prefer a short prioritized list (1–3) with the evidence that supports each cause.
Describe specific actions to address each root cause. For each action, note expected effect, how you'll validate it, and acceptance criteria.
Make a simple plan: tasks, owners, target dates, and required resources. Timebox pilots and describe how you'll measure early results.
Person responsible for driving the A3 to completion and reporting results.
Use a date or short timeframe (e.g., '2026-09-30' or '30 days from start').
Which metrics will you use to judge success? Include baseline and target values, and how often you'll measure.
How will you sustain and monitor the improvement? Who will check and when? Describe control actions if the metric drifts.
Capture what you learned, useful artifacts (photos, jig specs), and who to train so the improvement sticks.
Suggested questions: Do we agree on the problem and evidence? Is the goal clear and realistic? Have we tested the countermeasure quickly? Are owners and measures defined so the team can execute?
You may attach supporting files when submitting (photos, logs, drawings) if your interface supports uploads. If not, paste links or filenames here.
Optional: who completed this submission.
Optional: operator, team lead, engineer, etc.
For example: 'Please review countermeasure feasibility before pilot starts on Monday.'
