A six-question diagnostic intake routes the reader to the right starting tool based on which leg of the lean discipline is leaking fastest.
Daily Seven-Waste Spot-Check. Twenty minutes a week walking the operation and naming the seven wastes — overproduction, waiting, transport, over-processing, inventory, motion, defects — where they actually appear that week. Two worked examples: a B2C consumer packaging operator running spot-checks on a packaging line, and a B2B leather goods workshop catching custom-order rework as a defect waste rather than a margin line.
5S Weekly Workplace Audit. A weekly walk-through scoring the operation against Sort, Set in Order, Shine, Standardize, Sustain. Two worked examples: an auto-parts distributor running 5S across a multi-bay warehouse, and a Solo garment finishing workshop running 5S on a fabric-handling floor with high-mix production.
Kaizen Suggestion Log. Five minutes per week capturing improvement signals from the floor before they get edited out in the daily rush. Two worked examples: a garment finishing workshop running a structured suggestion process, and a Semarang commercial printing shop running B2B service kaizen.
Each tool carries a self-scoring rubric, a quick decision tree, and tier adaptations for single-owner shops, mid-tier businesses, and pre-IPO operations. A thirty-day plan at the back sequences the three tools so the rhythm forms without overload.
This companion draws on operator experience running businesses in Indonesia. Examples, currency, and operational texture reflect that origin. The frameworks carry across to small and mid-sized businesses in other emerging markets and many developed-market SME settings.
