Shop-floor management without shouting:
six steps that let the floor speak

A large mechanical assembly plant where the floor was messy, problems were settled by argument in meetings and delivery dates were chased by phone. What we did was not "tightening discipline" but six steps: put the KPIs on the floor, pick three priority problems, go to the floor, solve with A3, confirm the process, lead from the front.

Industry Large mechanical assembly Model Assemble-to-order Target A floor that impresses customers; lead time −25% Method Six-step SFM
1.14 → 1.3Productivity (+14%)
6 → 14New orders (+133%)
25%Shorter delivery lead time (short term, 8 → 6 weeks)
65.5%First-time-through rate (project-period recorded value)

The usual shape of shop-floor management: a problem appears, a meeting is held, people are told off, the meeting ends. Next month the same problem comes back. SFM does it differently — problems surface by themselves, are put in front of the team, and are solved one by one in priority order, without waiting for someone to shout.

The problem

  • Management could not be seen on the floor. Output, quality and delivery data sat in computers and in supervisors' notebooks; the operators could not see how far today's work should have gone.
  • Problems were settled by volume. Shortages, stoppages and quality issues were resolved by whoever shouted loudest; with no priority, the problem actually stopping the line was always last.
  • Improvement had no closed loop. A problem was raised, a meeting held, a corrective action written — and then nothing.
  • Lead time was chased. With an 8-week lead time, people only became anxious at week 6; nobody looked at the first four.

The six steps

KPIs and visual managementPut the key output, quality, delivery and safety measures where the team can see them. Not a report for the boss, but today's numbers for the team.
Priority problems: TOP1 / TOP2 / TOP3Chasing every problem equally means chasing none. Pick the three that matter most each day, ranked by what is blocking today, not by who complained loudest.
Go to the floorProblems are not in the meeting room. The supervisor stands at the workstation and watches how material moves, how people wait, how equipment stops.
Structured problem solving (A3)One page: symptom, cause, countermeasure, owner, completion date. Posted on the floor; the next meeting starts with that page.
Process confirmationOnce the countermeasure is set, confirm that it has become a process rather than another sheet of paper: who executes it, when it is checked, what happens when it drifts.
LeadershipTeam leaders and the shop manager are on the floor every day — not to inspect, but to lead the solving. Without this, the first five steps slide back.

What we did

  • Organised production to takt, changing "rush to the order" into "run to the beat".
  • Small parts on racks and JIS material preparation, so assembly gets the right parts, in the right quantity, at the right place, at the right time.
  • A shop-floor management board: today's KPIs, the TOP3 problems and A3 progress, all on the floor.
  • Turned "go to the floor" into a management routine rather than a slogan.

Results

+14%Productivity (1.14 → 1.3)
+133%New orders (6 → 14)
25%Shorter delivery lead time (8 → 6 weeks, short term)
65.5%First-time-through rate (project-period recorded value)

One thing this page has to say clearly

65.5% is a project-period recorded value for first-time-through; the original project material contains no before/after comparison. So this page does not say "raised to 65.5%" or "improved by X". The other three measures — productivity, new orders and lead time — all have before/after comparisons and can be quoted freely.

Who this is for

  • Large mechanical assembly plants, assemble-to-order, with many operations and many people on the floor.
  • Shop-floor management that depends on supervisors watching; when they travel, the floor drifts.
  • Companies that have run improvement rounds (5S, boards) but nothing stuck; a change of people puts it back to how it was.
  • Plants expecting a customer audit or visit, and wanting a floor they can show.
  • Not for: one-off small-batch work, very simple operations, or floors whose main problem is the equipment itself (that starts with TPM).

See the floor before discussing method

A two-day on-site diagnostic: where the KPIs sit, how problems surface, whether improvement closes the loop; identify three actions to start today. No system first, no training programme first.
