The comparison nobody runs

They were working the wrong lever — the only one they'd been given.

Changing the design

15–40%

Squeezing suppliers

3–8%

Purchasing fights for 3% because engineering already gave away 30%. The structure can be reopened.

What's in the guide

Eight places the money hides. The three biggest never appear on a parts list.

Requirements 10–25%A feature nobody asked for. A spec copied from a competitor.

Tolerances 5–15%Mostly copied, not calculated. Precision you throw away is precision you paid for.

Architecture 8–20%Every part costs far more than its price, once you add inspection, stock and a supplier to audit.

Materials 5–15%Sourcing 5–12%Process 5–15%Assembly 3–10%Packaging 2–6%+ ten cost myths, a worked example and a 12-question check

The section that costs us work

It also tells you when not to do this.

✕The volume isn't there. A 30% cut on 400 units saves less than the work costs.

✕The product is ending. You'd spend the savings on re-approval.

✕It's a price problem. A cheaper device just loses more cheaply.

✕The design isn't stable. You'd re-approve it twice.

Why that's in a marketing document: the fastest way to lose a technical buyer is to sell them a project that cannot work. If your answer to any of those is yes, we'll say so on the call, for free, before anyone signs anything.

Somewhere inside your product is a requirement no customer values.

The question isn't whether it exists. It's how much it has been costing you, every unit, every year.
