------- The Situation
Profits shrinking every year — and no one knew where the money was going.
Coimbatore has a thriving engineering cluster — pumps, motors, and industrial equipment supplying agricultural, industrial, and infrastructure sectors. Murali sir runs a unit making pump components — impellers, casings, and shafts. The business was stable, but margins were always tight.
When purchase bills were compared against production output, the math didn't add up. He was buying more raw material than the finished goods should have required. Somewhere, material was disappearing.
Raw material costs keep going up. I can't raise prices because competition is brutal. Every year, my profit shrinks a little more. I don't know how much longer this can continue.
— Murali sir, Pump Components Manufacturer, Coimbatore
The problem wasn't raw material prices — it was that nobody in the factory knew exactly how much wastage was "normal" versus how much was avoidable. There were no benchmarks. There was no measurement. The leak was invisible because no one had ever looked for it.
------- The Real Problem
Marketplace logic is different. The algorithm decides who gets seen.
In manufacturing, there's always some wastage — cutting losses, defects, scrap. But nobody in Murali sir's factory knew exactly how much was acceptable and how much was avoidable.
01
Consumption Norms
No standard for how much material each component should use. Workers used their judgment — sometimes more, sometimes less. Nobody tracked the difference.
02
Defect Accounting
Parts that failed quality checks were remade, but the wasted material from the first failed attempt wasn't accounted for anywhere in the system.
03
Actual Variance
Material variance was running at 12% — against an acceptable industry standard of 3–4%. That gap, undetected, was costing ₹40 lakh every year.
------- What We Did Together
Two weeks. 35 components. A measurement system built from scratch.
Working with Murali sir's production supervisor, a proper measurement system was built — not expensive software, not consultants, just a disciplined process of counting what went in and what came out.
1
Establish Material Norms
For each of the 35 components produced, exactly how much raw material should be used was calculated — including acceptable cutting losses and process waste. This became the benchmark every batch would be measured against.
2
Measure Actual Consumption
Every batch now had a material issue slip and a finished goods count. The supervisor could calculate variance: if 100 kg was issued and should have produced 40 pieces, but only 36 came out — where did the difference go?
3
Identify the Leakage Points
Three components had variance over 15% — far above the acceptable 3–4%. Investigation revealed: one was a training issue (new worker using wrong technique), one was machine calibration, one was a design flaw causing frequent rework.
4
Fix the Root Causes
Retrained the worker with proper supervision. Got the machine serviced and calibrated. Modified the component design slightly to reduce rework. Simple fixes — but they needed data to identify. None of them would have been found without measurement.
------- The Results
12% variance to 4%. ₹40 lakh saved. Without raising a single price.

Variance reports ongoing
Within 90 days, overall material variance dropped from 12% to 4%. That 8% difference, across ₹5 crore of annual material purchases, meant savings of ₹40 lakh per year — found entirely inside the existing operation without changing suppliers, raising prices, or cutting staff.
But the real value wasn't just the cost saving. It was the visibility. Murali sir now had a weekly report showing variance by component, by machine, by worker. Problems were caught early. Trends were spotted before they became crises.
