making operational
change stick.

Most transformation programs fail because the people doing the actual work were rarely part of the design — and because no one stayed close enough to make the change stick 
 
That's the gap LEF. exists to close.
 
LEF. is an operations and transformation consultancy for industrial leaders who want a clear, no-nonsense outside view of what's actually happening on their shop floor — not what the reports say. I help you diagnose where your processes are quietly leaking value, design changes the people running them will actually adopt, and build the discipline that keeps improvement going long after I'm gone.

FINDINGS.  ALWAYS THREE.

What I do
on Mondays.

Three engagement shapes — pick the one that matches the size of the problem. All three start with a half-day on the floor, not in the boardroom.

01

One-page scan

Two days on site. Three findings. One plan. Delivered as a single page — because if it doesn't fit on a page, it doesn't fit in anyone's head. Best for teams who suspect a problem but can't name it yet.

02

Lean Six Sigma deep dive

8–12 colleagues learn Lean Six Sigma by doing — not in a classroom. We pick a real process from your floor, run training and analysis side-by-side, and walk out with a prioritised plan your team owns because they built it.

03

Interim operations

Three to six months in the supply chain / operations manager seat — for teams between hires or in a turnaround. I bring a calm hand, a notebook, a positive outlook and the discipline to say no to the wrong work.

Measure what matters.
Feel the impact.

Step 01

Walk the floor

Half a day in the actual room — warehouse, line, office, kitchen. Watch what happens. Talk to the people doing the work, not the people describing it.

Step 02

Find the three

Of the dozens of issues you'll hear about, three are real and root-cause. The other dozens are symptoms. We name the three, on paper, in writing.

Step 03

One plan, one page

Each finding gets one owner, one metric, and one deadline. The whole plan fits on a single A4 — or it isn't a plan, it's a wishlist.

Let's start with
a walk.

Half a day on your floor, no commitment. If the three findings aren't useful, no invoice. That's the promise.
