Juran’s Discoveries
Used Pareto’s Rule
Big Q vs little q
Control vs Breakthrough
Project by Project Improvement
Vital Few and the Trivial Many
Using Pareto’s Rule
Must choose vital few projects that will have the greatest impact on improving needs
Majority of problems are caused by few causes
Big Q vs little q
little q - products in manufacturing
Big Q - All processes in all industries
Control vs Breakthrough
Should occur simultaneously
Control
Process-related activity that ensures processes are stable and provides a relatively consistent outcome
Breakthrough
Improvement that implies that the process has been studied and some major improvement has resulted in large, nonrandom imporvement to the process
