Overprocessing

32 improvements

Removing extra steps, tighter-than-needed tolerances, and over-engineering by matching the work to what the customer actually needs.

Where it comes from

Also called extra or over-processing, this is one of Ohno's seven wastes: effort spent beyond the point where the customer sees any added value.

What it looks like

Polishing or finishing a surface far smoother than the design requires.
Multiple sign-offs, re-entries, or inspections that add no value.
Using a heavy, high-precision machine for a job that needs neither.

Why it matters

Doing more than the specification calls for burns labor, energy, and machine time without raising what the customer will pay, so trimming work back to real requirements frees capacity for value-adding work.
