How to Calculate OEE: Step-by-Step Formula Guide

OEE = Availability × Performance × Quality. The formula takes thirty seconds to learn. The manipulation takes decades to unwind. I’ve seen plants using “standard” cycle times set 40% slower than actual equipment capability — manufacturing perfect Performance numbers while leaving massive speed improvement untouched.

Hidden Capacity Audit Checklist: The SCAN Protocol

Most companies operate at 40 to 60 percent of their true potential without knowing it — not because of broken equipment or underperforming employees, but because capacity bleeds invisibly across four dimensions nobody audits together: technical infrastructure, operational workflows, management bandwidth, and strategic resource allocation.

How ITW's 80/20 Strategy Built an $18B Empire

I spent years inside Illinois Tool Works watching the 80/20 operating system work at scale. In 1982, ITW was a $300 million industrial company fighting for survival. Today it generates over $16 billion in revenue with operating margins consistently above 25% — a 53x revenue transformation built on a single, ruthlessly executed insight: roughly 20% […] Read More

What Is Portfolio Complexity Cost? A Hidden Killer

Your finance team can tell you your product costs. They cannot tell you your complexity costs.

5 Signs Your Best Customers Are Destroying Value

Harvard Business Review research shows service cost variation between customers often exceeds ten times within the same company — but standard accounting averages those costs across everyone, systematically overstating profitability for your most demanding accounts. Your customer service team already knows the truth. They spend 80 percent of their time on 20 percent of customers. […] Read More

Why Firing Customers Actually Increases Revenue

The Revenue Liberation Paradox is the most counterintuitive math in business: every dollar of unprofitable revenue eliminated releases three to five times that value in resources for profitable expansion. Harvard Business Review research shows the spread between most profitable and least profitable customers within the same company often exceeds ten times — yet standard retention […] Read More

3 Customer Profitability Myths Costing You Millions

Three myths destroy more organizational value than any competitor ever could: all revenue is good revenue, big customers are always profitable, and more products mean more sales.

Activity-Based Costing vs Traditional: True Profit

Traditional costing takes overhead and spreads it proportionally across all units using a single driver like labor hours. It completely ignores that Product A requires one setup per 10,000 units while Product B requires one setup per 100 units. That difference — invisible in traditional reporting — is often the difference between profit and loss. […] Read More

Seven Quadrant 4 Mistakes Destroying Your Profits Now

Quadrant 4 customer-product combinations typically destroy 50 to 100 percent of total company profits while contributing only 5 to 15 percent of revenue. That math alone should end the conversation. But companies commission study after study, spend 90 days perfecting profitability data, and achieve 50 percent lower returns than organizations that act within 30 days. […] Read More

Decision Rights Matrix Template for Manufacturing

McKinsey research shows organizations with clear single-point decision authority make decisions two to three times faster than those with distributed accountability. Yet most manufacturers still run RACI matrices that assign both “Accountable” and “Responsible” to different people — which creates precisely the ambiguity it claims to resolve. When someone is Accountable and someone else is […] Read More
