“Our margins are shrinking and we can’t see where the money is leaking.”
Revenue is fine, but margin keeps eroding — and the P&L doesn’t show why.
What you’re facing
Sales are steady or growing, but margin keeps slipping. Material costs explain some of it, not all. Finance asks operations where the money is going; operations points at a dozen things; nobody can put numbers on any of them.
You suspect the answer is the “hidden factory” — the second, invisible operation that exists to fix, re-handle, expedite and inspect. But until it has a dollar value, it can’t compete for attention or funding.
What this is costing you
- •Scrap and rework spread across departments and cost centers
- •Premium freight and expediting, buried in logistics
- •Overtime driven by rework and schedule recovery
- •Extra inspection added after escapes and never removed
- •Warranty and customer concessions
The questions you’re probably asking
Isn’t this a quality department problem?
Quality losses are part of it, but the hidden factory spans operations, logistics, maintenance and planning. Quantifying it is Lean Six Sigma work that produces a business case, not a quality report.
Our accounting system doesn’t track these costs. Can we still do this?
Yes. Most of the data exists in scrap logs, freight invoices, time records and work orders. The work is collecting it with rules that prevent double-counting.
How is this different from a corrective action project?
Corrective action fixes a specific problem inside the quality system. This work finds and ranks where the money is going so you know which problems are worth fixing first.
What to do first
- 1Pull 6–12 months of premium freight invoices — it is often the fastest eye-opener.
- 2Total scrap and rework costs, including labor and material, not just scrapped parts.
- 3Tag overtime hours by cause: demand, rework, schedule recovery, absence.
- 4Get finance in the room early so the numbers are built the way they will be judged.
What best practice says
Cost of poor quality (COPQ) and hidden-factory analysis group losses into prevention, appraisal, internal failure and external failure. The useful extension for margin work is adding the flow costs — premium freight, expediting, overtime — that quality models often leave out.
Credibility depends on method: consistent definitions, finance-approved rates, and controls against counting the same dollar twice. The output is a ranked savings pipeline, not a single scary number.
Method, sized to scope
Hidden-factory quantification (COPQ plus flow costs), a ranked savings pipeline, then DMAIC or Kaizen projects on the largest losses.
The Exceleor Path, applied to your situation
Every engagement across the Exceleor family follows the same eight stages: Understand, Execute, Sustain. About the Exceleor Path
1. Discovery
In your situation: We gather scrap, rework, freight, overtime, inspection and warranty data with finance’s input.
2. Define the engagement path
In your situation: We build a ranked savings pipeline and assign the right method to each loss.
3. Training
In your situation: Your team learns the cost model and the rules against double-counting.
4. Implement & engage
In your situation: We run DMAIC or Kaizen projects on the top losses.
5. Verify
In your situation: We verify savings with finance using the agreed rules.
6. Validate
In your situation: We validate that savings show up in the P&L over time.
7. Transfer ownership
In your situation: Finance and operations own the hidden-factory tracker together.
8. Sustain & grow
In your situation: We refresh the pipeline so the next wave is always funded by the last.
What you’ll have at the end
- A dollar value on the hidden factory that finance accepts
- A ranked savings pipeline
- Completed projects with verified savings
- A shared tracker owned by finance and operations
Why QMSLean
We start from the business symptom, not a favorite tool. The method — A3, Kaizen or DMAIC — is chosen to fit the size of the problem.
We work on the floor and in the office with your people, and we build the sustain system before we leave, so the gain is still there after we are gone.
And when the root of the problem sits outside Lean, the Exceleor family of companies covers quality systems, supplier quality, EHS and leadership.
