Hunting the 8 Wastes (Muda)
Scan your process for eight specific waste types, not vague general waste.
Goal
Replace random hunting for "improvements" with a systematic scan against eight known waste categories (TIMWOODS).
Steps
-
1
Read the eight types: Transport, Inventory, Motion, Waiting, Overproduction, Overprocessing, Defects, Skills (underused talent).
Expected Outcome
Immediate
You discover at least two waste types you never previously classified as a problem (e.g., a skilled employee's talent going unused).
Evidence base
School: Toyota Production System / Lean
Founders: Taiichi Ohno (1988)
Taiichi Ohno classified seven original waste types in "Toyota Production System" (1988); Lean practitioners later added the eighth (underused skills), forming the TIMWOODS acronym.
