When the Schedule Is “Managed” but Still Sinking Not everything can be turned into a process—especially in product development, where discovery and uncertainty are unavoidable. But there is a dangerous gap between acknowledging uncertainty and pretending it is under control. The image illustrates a familiar scenario: a project manager confidently “monitoring and controlling” while the […]
BOM Data Integrity in a “Post‑BOM” World (and Why I Disagree) Reading “2026 – The year we have to unlearn BOMs!” immediately brought back decades of scars from broken configurations, field failures, and costly recalls rooted in poor BOM data integrity. The thesis that classic assemblies and traditional BOM thinking have become obsolete misses […]
When the Margin Is Unknown, Control Becomes Reaction Not everything can be turned into a process. This is especially true in early product development, where learning, discovery, and iteration dominate. However, when ambiguity persists beyond its appropriate stage—especially around dimensions, tolerances, and margins—organizations unintentionally transfer risk downstream. The image illustrates a simple truth: when the […]
The PFMEA–Control Plan Connection in Manufacturing A robust PFMEA connected to a control plan strategy is essential when launching a new manufacturing line or improving an existing one. The Process Failure Mode and Effects Analysis (PFMEA) identifies where and how a process might fail, while the control plan documents how those risks will be monitored, […]
Factory Acceptance Test (FAT) and Site Acceptance Testing (SAT) Overview In product development, acceptance testing is a cornerstone of predictable, high-quality system deployment. As one of the authors of Configuration Management Theory and Practice, Testing of Complex and Embedded Systems, and multiple industry articles, I often emphasize that product and system verification must validate performance across both controlled […]
Openness Builds Stronger Cultures In the past few weeks, I’ve been reflecting on a pattern that appears across high-performing, logic-driven organizations: brilliant teams slowly losing momentum because the fight to be proper overshadows the desire to understand. Then I saw this LinkedIn article, which is the genesis of this article. I have worked on teams […]
Introduction Every organization faces unexpected issues—but how you respond defines your success. When deviations from standard procedures are mismanaged or ignored, the result can be catastrophic: product recalls, regulatory fines, and irreparable brand damage. A deviation in manufacturing refers to a temporary or unplanned departure from approved procedures, specifications, or standards during the production process. […]
Transparency in Testing and Why It Matters Before going into this post, I want to apologize to Rachel Evans for not being able to attend the Automotive Testing Expo in Novi, Michigan. This goes beyond her and to all who had planned to meet me and chat about this vital topic area of product testing. There was […]
Jon M Quigley The Benefits of Swim Lane Process Flows for Engineering, Manufacturing, and Procurement Swim lane process flow benefits in product development. Product development is a complex journey that involves multiple teams and departments, including engineering, manufacturing, and procurement. This requires coordination across the board, not optimization of a single department, but balancing the […]
Work Instruction Updates: Capturing Continuous Improvement and Tribal Knowledge By Jon M Quigley Why Work Instruction Updates Matter Work instruction updates are more than administrative chores; they are potent tools for continuous improvement and the preservation of tribal knowledge. As organizations adapt to changing customer needs, technological shifts, and workforce turnover, the need to capture, […]
