A practical digital ebook for plant quality engineers and manufacturing leaders who need to assess legacy statistical process control practices against the 2026 harmonized VDA-AIAG SPC requirements without stopping production or manually reviewing every historical record. You will learn how to set a risk-based boundary, establish the plant’s actual current state, verify measurement and data integrity, interpret capability results responsibly, and connect shop-floor behavior to documented requirements. The method turns an unbounded review into a focused evidence plan with clear owners, production constraints, checkpoints, findings, and follow-up actions. Across the seven authoritative chapters—from The Boundary Is the First Control through Close the Assessment With Evidence—you will build a defensible assessment that prioritizes product and process risk while preserving operational continuity. Use the ebook as a focused reference during planning, interviews, line observation, evidence review, and leadership reporting. Delivered digitally for convenient online access.
