The Floor Walk

We Read the Factory Before We Read the P&L

Most consultants arrive with a framework. We arrive with steel-toed boots. The first 48 hours of every engagement are spent on the floor — timing changeovers with a stopwatch, mapping material flow by hand, watching where supervisors cluster when things go wrong.

We're looking for the constraint that's running the plant — not the one showing up on the monthly report. They're rarely the same thing.

"The bottleneck was a 94-minute changeover on Line 4. It had been that way for six years. Nobody had timed it."

Roadmap

The Roadmap

Intervention Sequenced by Payback, Not by Convenience

The roadmap is built around one question: which constraint, removed first, creates the most capacity for removing the next one? We sequence interventions by velocity of payback — typically the constraint with the highest dollar-per-week recovery rate goes first, regardless of how uncomfortable that is.

The Sequencing Logic

The SMED workshop on Line 4 came first — not because it was easiest, but because each recovered minute freed 6.3 units of daily capacity. That capacity funded the next intervention.

By week 10, the client's own maintenance team was running the methodology. Our role shifted from leading to coaching. That transition is the point.

Execution

The Embedded Model

We Work Inside the Building, Not from a Slide Deck

The Forge team embeds on-site for the duration of the execution phase — typically 8 to 14 weeks. We run Kaizen events with your operators, not for them. The methodology transfers to your team by design. When we leave, the system runs itself.

Who We Work With

Second-generation plant owner

Margins eroding 200bps/yr. Son wants to sell. Father built it. Forge found $1.8M in recoverable throughput in the first diagnostic.

+18% OEE · 11 months

Operations VP — PE-backed portfolio

18 months to EBITDA target. Two prior consultants had come and gone. Forge embedded on-site for 14 weeks.

+27% throughput · EBITDA target hit M+16

Family-owned contract manufacturer

Doubling output without a new building. Forge redesigned material flow and eliminated 3 of 7 non-value steps.

The Proof

We Don't Leave Until the Numbers Are in the System

Every engagement closes with a measurement dashboard built inside your existing ERP — no new software, no subscription. OEE, TAKT adherence, and changeover time tracked daily by your team, not ours.

The EBITDA impact is calculated conservatively — we use your finance team's cost assumptions, not ours. If the number isn't in the P&L within 18 months, we come back.

"Forge found $2.1M in year one. We'd had three lean consultants before them. None of them had timed a changeover."

The Diagnostic — First Engagement

The Constraint Is Already Visible. We Just Have to Look.

A Forge diagnostic engagement runs 8–12 days. You receive a constraint map, a prioritised intervention roadmap, and a quantified recovery estimate — signed by our team. If we can't identify at least $1M in recoverable throughput, the diagnostic is on us.

If the diagnostic doesn't surface at least $1M in recoverable throughput, we refund the engagement fee. We've invoked this clause once in 47 engagements.
