Quality Improvement in Product Development: The Horse Isn’t Even Near the Water Before we go any further with this blog post, I need to note that this stems from recent consulting work that demonstrated the principle.  But that would not have been enough even though these thoughts were rolling through my head.  The catalyst was […]

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.  […]

Deterministic vs Probabilistic: Definitions that Matter in Engineering In engineering, deterministic vs. probabilistic refers to how we model cause-and-effect relationships and uncertainty.  The difference between the two requires concepts that are important and should drive how we behave.  A deterministic view assumes that the same inputs will always produce the same output; given the system […]

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 […]

A Product Is Both Good and Bad—Until Tested Not everything can be turned into a process. This is especially true early in product development, where ideas evolve faster than data. But there is a dangerous phase where uncertainty masquerades as progress. Like Schrödinger’s famous thought experiment, an untested product exists in a paradoxical state: it […]

When Testing Competes with the Calendar Not everything can be turned into a process—especially early in product development, where learning is still underway. However, one decision consistently creates downstream damage: allowing testing to compete directly against launch dates. The image captures a familiar and dangerous scenario—standing still on the tracks while “time to ship” accelerates […]

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, […]
