20 Angles to Never Run Out of Kaizen Ideas (With Real Examples)

Published: Author: Haruka Motozutsumi

“Please submit one improvement proposal this month.” For many diligent teams, that request is where the pen stops. This article shares 20 angles that keep ideas flowing, with real examples.

Why ideas “run out”

The cause is simple: people look only for big improvements. Equipment-level improvements appear a few times a year at best. Meanwhile, veterans grow used to inconvenience and stop seeing everyday waste.

The fix is a change of lens: capture the 5-second annoyances.

Seven lenses of waste (the classic TPS “7 wastes”)

  1. Overproduction — are lot sizes bigger than needed?
  2. Waiting — time spent just watching a machine finish?
  3. Transport — is the walk to tools and parts the shortest possible?
  4. Overprocessing — is that step truly necessary?
  5. Inventory — time lost searching for storage spots?
  6. Motion — too much crouching, reaching, re-gripping?
  7. Defects & rework — how many times did the same rework happen this month?

Thirteen more: safety, quality, changeover

  1. Near-miss locations (example: tape-marking a walkway step → zero trips)
  2. Hard-to-don protective gear
  3. Jigs that turn two-person jobs into one
  4. Inspection points that are easy to miss
  5. Standards that give the same result regardless of who works
  6. Converting internal setup to external setup
  7. Fixed positions for tools (example: shadow boards cut 30 seconds of searching per retrieval)
  8. Lighting and signage visibility
  9. Eliminating re-keying between forms
  10. Standardized handover notes
  11. Writing procedures for the exact spots where newcomers stumble
  12. A fast lane for reporting abnormal noise or vibration
  13. Reducing “why do I get asked twice?” with better information sharing

Turn angles into a system that collects itself

Knowing the angles isn’t enough — unrecorded insights never become proposals. The rule: capture must be immediate, effortless, and recorded. With paper forms, insights evaporate somewhere between “I’ll write it later” and the end of the shift.

When AI shapes voice memos into proposal documents, the shop floor only needs to murmur. Every site we’ve seen multiply its proposal count did one thing without exception: it removed the burden of writing.

FAQ

Why do kaizen ideas dry up every month?

Usually because people hunt only for big improvements. Switch to capturing the small “5-second annoyances” of daily work and ideas start flowing naturally.

Are tiny improvement proposals worth submitting?

Yes. Small proposals have high adoption rates and build the proposal habit. Annualized, their financial impact is often substantial.

What makes an idea-collection system work?

Capture must be immediate, effortless, and recorded. Paper forms kill insights through writing burden — voice memos with AI documentation work far better.
