Red Risk Experiment
summary
A live reworking of the red bead experiment runs through 4,000 beads (3,200 white, 800 red) to show that random variation yields about ten defects per draw and a stable voice of the process 6–17, so firing, yelling, OKRs or adding staff never hits the target of 200 non-defective beads and often makes outcomes worse. Builds are simple scoops and paddles; analysis uses control‑chart thinking, supplier focus, retrospectives and Toyota Kata to diagnose the system rather than tamper with it.
