Writing on wire harness quoting
Comparisons, technical fundamentals and perspective from the practice of estimating — every piece signed by its author.
Technical fundamentals
The copper surcharge, explained: how the copper number, the quotation and the copper base set a cable price
Cable is priced as a base price plus a copper surcharge. What the copper number, the DEL notation and the copper base each mean, the arithmetic that ties them together, and what it changes in a harness quote.

Comparison
Quoting wire harnesses in Excel or an ERP: what it actually costs
Why wire harness quoting still lives in spreadsheets, the four costs that never appear in the sheet, and why moving it into the ERP does not solve the underlying problem.

Perspective
Quoting is the bottleneck, not production
Four decades of investment made harness manufacturing faster and left quoting untouched. Why the constraint on growth moved to the estimating desk, what a slow quote really costs, and what changes when pricing stops being scarce.
