Lean Training That Survives Contact With the Shop Floor

Most lean training is not wrong. It is just abandoned. People come back from two days off site able to describe the seven wastes, and walk into a factory that is organised exactly as it was on Friday, with the same queues, the same expediting and the same manager who needs the job out tonight. Within a month the folder is on a shelf and nothing has changed.

That is not a failure of the delegates. It is a failure of design. If the training is not built into a change the business has actually committed to, it will not survive contact with the shop floor.

Train on your own value stream

The single biggest improvement you can make to lean training is to stop teaching it on somebody else's example.

I learned this at Goodrich, where we ran week-long improvement events. The teaching was not in a classroom — it was in front of the process, with the people who ran it. Monday was understanding the current state and measuring it honestly. By Wednesday the team was trialling a different layout. By Friday there was a changed process and a set of actions with names against them. The training and the improvement were the same activity.

Compare that with a delegate folding paper aeroplanes in a hotel conference room. The simulation teaches the principle, and the principle is real. But the delegate has not had to argue with a setter about where the tooling trolley lives, or discover that the reason for the queue at the deburring bench is a planning rule nobody has questioned in nine years. Those arguments are the training.

So: run the training on a real value stream, with real parts, real data and the real people. Pick a product family that matters, not the easiest one.

Who needs what

Not everybody needs the same depth, and sending everyone on the same course wastes money and goodwill.

• Awareness, for everyone on the floor. An hour or two. What waste looks like in this factory, why flow matters more than keeping every machine busy, and how to raise a problem without it being treated as a complaint. Use your own parts and your own photographs.
• Practitioner, for supervisors, team leaders, planners and engineers. The tools they will actually use: value stream mapping, standard work, 5S done properly rather than as a tidying exercise, setup reduction, and basic problem solving. These are the people who make or break sustainment.
• Facilitator, for the handful who will run events. How to scope an improvement, gather data that will withstand challenge, run a week with a cross-functional team, and close actions. You need two or three of these, not twenty.

A business of 80 people does not need forty practitioners. It needs eight good ones and a management team that will not quietly undo their work.

The sustain problem is a management problem

Here is the uncomfortable part. Most lean improvements are reversed by managers, not by operators.

I have watched an owner-managed business redesign a flow properly — genuinely good work, cells arranged around the product, queue time cut — and then revert it within weeks because a big order came in and the old layout felt safer under pressure. Nobody was being obstructive. Under stress people reach for what they know.

Two things protect against this:

Standard work. If the new method is written down at the level of detail the job actually needs, there is something concrete to defend. If it only exists in the heads of the people who were in the room that week, it evaporates the first time they are on holiday.

Visual management. At Moog we put performance where people could see it — not a monthly report circulated to managers, but the state of the work, visible on the floor, updated by the people doing it. When the measure is visible, a slide backwards is obvious within a shift rather than at the end of the month. That is what makes a reversal uncomfortable enough to be questioned.

Train both of these as part of the lean training, not as a separate initiative. They are the mechanism by which everything else survives.

Expect the five per cent

In any workforce there are a few people who do not want the change to succeed, usually because the current mess suits them or because they have seen three previous initiatives come and go. You will not convert them with a training course.

What you can do is be clear, early, and not pretend the resistance is not there. Most of the organisation is watching to see whether this one is different. If the first improvement is allowed to quietly rot, they have their answer and the next attempt is much harder.

Did the training work?

Judge it on the process, not on attendance. Useful evidence after three months:

• Is the standard work still being followed, and has it been updated when something changed?
• Are the visual boards current, and filled in by the team rather than by one keen supervisor?
• Has a second improvement happened without an external facilitator in the room?
• Has the measure that justified the work — changeover time, queue time, on-time delivery — actually moved and stayed moved?

That last one matters. Lean training that produces a well-received course and no change in OTIF or margin has not worked, however good the feedback forms were.

Frequently asked questions

How long should lean training take?

Awareness is one to two hours. Practitioner training is best delivered as a week-long improvement event on a real process, because the event is the training. Facilitator capability builds over two or three events with support, not in a classroom.

Should we train everyone at once?

No. Train the people involved in the first improvement, do the improvement, then widen. Training a whole site before anything changes creates expectation you cannot meet, and the enthusiasm has usually gone by the time their area's turn comes.

Do we need a certified lean qualification?

Rarely. Belt qualifications matter if a customer or a career path demands them. For a manufacturing SME trying to improve delivery and margin, capability in your own value stream is worth more than a certificate, and considerably cheaper.

What if we have tried lean before and it did not stick?

That is common and worth understanding before you start again. The usual causes are training detached from a real change, no standard work to defend the new method, and no visible measure. Fix those and the second attempt goes very differently.

We run lean and continuous improvement training on your own processes, delivered by people who have run factories rather than only taught about them. See our training services, read more on building a culture of continuous improvement, or get in touch.
