The Map Has Drifted: Remap the value stream, run an OEE deep-dive, and rebuild process costs once a quarter to find the constraint the daily picture hides.

A six-question diagnostic intake routes the reader to the right tool based on which calibration is most overdue. Operators running all three of the op-06 weekly instruments will typically know the answer before they finish the intake questions.

The book covers three once-per-quarter instruments.

The Full Value-Stream Remap reconstructs the true sequence of work across the entire operation, including the informal handoffs that have never appeared on any process diagram. Informal steps are the ones that take time, absorb attention, and never get discussed because everyone treats them as normal. Two worked examples: a distribution company finding informal steps clustering in the dispatch stage, and a Semarang food production company finding four informal steps in packaging that add an average of forty-seven minutes per batch without appearing on any shift log.

The OEE Deep-Dive is a structured Overall Equipment Effectiveness audit that distinguishes intrinsic constraint from upstream starvation — the distinction that standard production reporting routinely obscures. Two worked examples: a dispatcher role under apparent labour shortage where OEE analysis surfaces idle-time attribution, and a Bekasi steel fabrication shop where the welding stage appeared to be the capacity constraint until OEE measurement redirected attention to the upstream cutting stage running at 61 percent availability.

The Process-Cost Reconstruction rebuilds the true unit cost of the dominant process from current numbers, surfacing cost components nobody has owned in twelve months. Two worked examples: a distribution company computing per-order cost for the first time since its route network changed, and a civil engineering consultancy reconstructing per-project cost across multiple service categories and finding a cost differential that had been averaged away.

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 quarterly plan at the back sequences the three tools across one full quarter.

Written from the seat of an Indonesian operator. The frameworks apply broadly to SMEs in other emerging markets and to many developed-market settings.
