Systemic Quality and "The Iron Triangle" of Quality, Cost and Schedule.

[Full post on other blog.]

The work on Safety and Quality systems by James T. Reason and Charles H. Perrow redefined the world of Quality, showing up in acceleration Safety in Aviation post-1970.

But what do you call this approach?

I'd like to suggest, "Systemic Quality".

Perrow called them "Normal Accidents" and Reason "Organisational Accidents". Both were talking about System created Accidents. Where multiple events, not individuals, are the cause of unintended poor outcomes. But neither coined a term for this approach to Safety and Quality.
My reasoning for the naming is:
Name the approach after the cause addressed, Systems create the problems, so it's Systemic Quality.
The text below is adapted from a piece on suggesting Medicine become a Modern Profession, like Aviation.

What Dr W. Edwards Deming understood so well is that Quality, Process Improvement and Performance Improvement are linked through the same fundamental:
Deliberate, focussed review of work outcomes with intentional Learning and Adaption are necessary for, and common to, all three.
This is enshrined in Deming's P-D-S-A (Plan-Do-Study-Act) cycle, which he called the Shewhart Cycle.

Systemic Quality through its design and nature improves Safety, Performance/Productivity and Economic Performance/Profitability.
Something that Apple Inc knows and Microsoft, the long-time market leader, does not.
