Supply Chain by Design: The S3 System for Building Chains That Execute Design — Not Heroics

Your forecast accuracy is 87%. Your supplier on-time delivery is 94%. Your service level has declined for three consecutive quarters.Which metric is failing?Neither. And that is the problem this book exists to solve.Supply chain execution does not fail because components underperform. It fails because the connections between them were never designed. Execution lives in the interfaces - and interfaces belong to no function, appear on no dashboard, and are owned by no one.Supply Chain by Design is the second volume of the S3 Execution Series. It takes the S3 Strategy Execution Model - Strategy, System, Synchronization - and applies it specifically to the supply chain, where organizational decisions become operationally visible faster than anywhere else in the business.What you will be able to do after reading it - Calculate your Heroism Dependency Index - the proportion of critical processes that depend on specific people rather than designed systems - Score your supply chain across four diagnostic blocks and identify which of five structural weakness patterns you are actually facing - Measure the five critical cross-functional interfaces with the Interface Quality Scorecard - Calibrate your S&OP rhythm to environmental velocity instead of inherited convention - Design the governance that holds an architecture together when financial and commercial pressure arrives - Sequence a transformation across three phases without compressing the gates that protect it Who this is forSupply chain directors and VPs, CSCOs, COOs with supply chain responsibility, and operations leaders who have run improvement programs that produced real gains without closing the gap they were funded to close.This is not a book about better forecasting, leaner processes, or smarter technology. It is a book about the architecture underneath all three. Written by a practitioner with twenty years leading supply chain transformations across specialty chemicals, industrial lubricants, payment technology, agroindustry, and industrial manufacturing.Fourteen diagnostic instruments. Eighteen chapters. One question: was your supply chain designed, or was it assembled?
