Name the several important lessons for managers from the Red Bead experiment.
What is
1) Quality is made at the top?
2) Rigid procedures are not enough?
3) People are not always the main source of variability?
4) Numerical goals are often meaningless?
5) Inspection is expensive and does not improve quality?
What is
Variation exists in systems and, if stable, can be predicted?
All the variation in the production of red bead came entirely from the process itself?
Numerical goals are often meaningless?
Management is responsible for the system?
