Your plant already has the capacity. It's buried in the process.

I find the hours your operation loses to travel, changeover, rework, and unmanaged shift routine — then I rebuild the process so they come back. Stopwatch in hand, on your floor, in your language.

The premise

Most capacity problems are not capacity problems.

When a plant can't hit its number, the reflex is to add a shift, add a line, or add people. Sometimes that's right. More often, the constraint isn't the equipment — it's the twenty-two minutes an operator spends walking, the fixture that takes four attempts to seat, the cool-down cycle nobody has questioned since it was commissioned, or the shift handoff that transfers no information.

Those losses don't appear on a P&L. They appear as a quota that everyone privately knows is soft. Finding them requires someone willing to stand at the station with a stopwatch and ask why — repeatedly, and without an agenda about the answer.

That's the work. Not a slide deck about lean. A measured baseline, a specific list of what's costing you time, an engineered fix for each one, and a management routine that keeps the gain after I leave.


What I do

Four things, done to a documented standard.

01

Time, method & simulation study

Element-level timing of every station, with a written cause for each loss — then a discrete-event model to prove the fix before you buy it.

  • Baseline vs. quota analysis
  • Station-level element timing
  • Discrete-event simulation (Arena)
  • Capacity, staffing & line balancing
02

Management & project systems

The routine that makes a gain permanent: shift transitions, huddles, dashboards, and a project-management process that lands work on a schedule.

  • Shift transition & huddle design
  • Daily short-interval control
  • Project management process & templates
  • Current-state & target-state MOS flows
03

Process, tooling & facilities design

When the fix is hardware, I design it — drawings, BOMs, sourced parts — up to plant-scale facility and environmental systems.

  • Fixture & workholding design
  • Automation cell conversion
  • Assembly/disassembly process sheets
  • Facilities & environmental (wastewater) design
04

Controls, automation & work instruction

The control-system layer — SCADA, automation controllers, and protection — plus standard work that survives contact with the floor.

  • SCADA, SEL RTAC & IEC 61850 / GOOSE
  • Automated protection-system monitoring
  • Digital & AR work instructions
  • Traceability & ergonomic assessment

Where this applies

Sectors I know from the floor up.

If your process involves discrete units moving through stations on a clock, the method transfers.

General mid-market manufacturing Capacity studies, OEE loss trees, supervisor development, daily management routine, ergonomics and workstation design

How an engagement runs

No surprises, no open-ended retainer.

PHASE 01

Analysis

One to three weeks on site. I time the work, map the flow, interview supervisors, and build the baseline. You get a written opportunity list with an hours-and-dollars figure attached to each item.

PHASE 02

Scoping

We agree which opportunities are worth pursuing and what the target is. If the analysis says the honest answer is "your process is fine, buy another line" — that's what the report says.

PHASE 03

Implementation

Engineered fixes get designed and installed. Routines get built and run with your supervisors, not at them. I work the shift the problem is on, including nights.

PHASE 04

Handover

Documentation, dashboards, and a trained supervisor group. The measure of a good exit is that the number holds ninety days after I'm gone.

Next step

Tell me what number isn't moving.

A first conversation is free and usually takes half an hour. If I don't think I can help, I'll say so and point you at someone who can.
