Failure 04 — No explicit risk posture

Safety stock on precision bearings at Penang DC is set to two weeks of cover. The setting was made in 2022 by an analyst who calibrated it for a 95% service target under that year's demand and lead-time distributions. The analyst left in 2023. Neither the demand distribution nor the lead-time distribution match 2022 anymore. The CSCO doesn't know the setting exists. The CFO doesn't know it exists. It is doing real work — eight figures of working capital are sitting in inventory because of it — and it is invisible.

Every supply plan implicitly chooses how much variability to cover. That choice is real, the dollars are real, and the choice itself is rarely made consciously. It is buried in a master-data cell, set once, drifted ever since. What it would look like if the choice were explicit: three named postures — Conservative, Balanced, Lean — each with stated commitments per driver and each dollarized at the working-capital and EVA level. Conservative carries demand cover at the 90th percentile, lead-time cover at the 95th, and a margin floor of 28%; it absorbs $8.4M of additional working capital relative to Balanced for 1.8 service points. Lean carries demand cover at the 65th percentile, releases $11.2M of working capital relative to Balanced, and accepts 2.3 service points of exposure.

Each posture becomes a deliberate executive choice surfaced at leadership level, not a buried default. Each carries forward into every decision the system makes — every safety stock, every PO release timing, every customer allocation under scarcity, every margin-floor enforcement. A decision policy is, at its root, the organization's posture for converting uncertain environments into resilient recommendations. In most organizations today, that posture is being chosen by default, not by design.
