Control Plan Gaps: What Most Quality Professionals Overlook Control Plans are among the foundational quality tools within Advanced Product Quality Planning (APQP) and are required by IATF 16949. They help organizations define process controls, monitor product characteristics, and establish reaction plans when performance deviates from expectations.  This blog post is prompted by a LinkedIn post […]

PPAP Risk Management: Why Most PPAP Approvals Still Fail at Production Launch I recently reviewed a visual guide titled “How to Create PPAP – Complete Practical Master Guide.“ Like many PPAP references circulating online, it does an excellent job explaining the documentation requirements, submission levels, and elements of the Production Part Approval Process. What it […]

Product Development Writing — Engineering Beyond Engineering I never intended to become a writer. I intended to become a product development professional. Like many engineers, I initially believed technical competence and creativity would largely determine success. Certainly, strong engineering capability matters. But over time, reality exposes a far more complicated truth: Products rarely fail solely […]

The reflex response after a defect escape is often predictable: add more inspectors. More containment. More gate reviews. More signoffs. More checklists. The organization feels pressure to “do something,” and inspection fallout becomes the preferred reaction because it is visible, immediate, and politically safer than confronting systemic process weakness. The problem is that inspection fallout […]

PFMEA Control Gap: Control Plan Tools That Fail During Transition The PFMEA (Process Failure Mode and Effects Analysis) control gap is one of the most common root causes of quality failures in manufacturing. It occurs when the Process Failure Mode and Effects Analysis (PFMEA) indicates that risks are controlled, but actual shop-floor execution indicates otherwise.  […]

APQP Testing Limitations in Automotive and Manufacturing Quality Advanced Product Quality Planning promises robust launches, but APQP testing limitations often emerge when teams equate “meets spec” with “fit for use.” APQP testing limitations become most evident when products pass all defined tests yet still fail in customer applications, field use, or long-term durability. The root cause […]

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, […]

The PPAP Process Flow The PPAP process flow (Production Part Approval Process) is a cornerstone of modern manufacturing quality systems, particularly in automotive and industrial sectors. It ensures that every part delivered meets customer expectations by validating that the production process can consistently produce conforming components.  PPAP is part of the Advanced Product Quality Planning […]
