Better tools begin with better questions.

SAAFD is grounded in a simple conviction: improvement work gets stronger when teams investigate conditions, test ideas, and build systems—not blame.

The reason for SAAFD

Quality tools matter. So do their limitations.

Familiar tools such as 5 Whys, fishbone diagrams, FMEA, and corrective action methods provide valuable structure. But when teams rush through definitions, accept the first plausible cause, or rely on weak controls, even a well-known tool can give a false sense of confidence.

SAAFD is an effort to extend and connect these tools into a more rigorous, practical method—one that helps people anticipate failure, examine complex pathways, and create sustainable prevention.

Principles that shape the work

Focus on systems rather than blame.
Prefer direct evidence over a persuasive story.
Make assumptions and uncertainty visible.
Improve the prevention mechanism, not only the response.
Use AI as a thinking partner, not an authority.
Make methods practical enough for real teams.

About the author

Robert King

Robert King brings a long-standing perspective on the evolution of quality improvement. His background includes leadership at GOAL/QPC from its inception and experience working within the quality movement, including with W. Edwards Deming.

With SAAFD, the aim is to respect the enduring value of earlier methods while examining where modern, interconnected work demands stronger questions, deeper investigation, and more reliable prevention.

SAAFD is an independent methodology and is not presented as a program of GOAL/QPC or of any other named organization.

The purpose of the book and programs

Explain the method clearly, make it usable in practical situations, and help organizations move from reactive corrections toward better insight and prevention.
