Learn the method by playing it
Five interactive activities that drill the exact reflexes the RCA workshop builds. No sign-up, no score-keeping — just practice.
The Five Whys Drill
Walk a real production failure down five layers. Pick the answer that goes deeper, not sideways.
The case
Line 3 stopped for 47 minutes last night. The packaging wrapper jammed mid-run.
Why did the line stop?
Root or Symptom?
Rapid-fire classification. Statement appears, you decide: symptom, cause, or root cause.
Customer complaints about leaking cartons rose 30% last month.
Fishbone Builder
Sort twelve causes into the six M categories before the clock runs out.
Pick a cause, then pick its category
Loss Hunter
A live production line. Spot the eight wastes as they appear — sixty seconds.
Activities will run past. Click only the waste — let the value-adding steps go by.
The eight wastes: Defects, Overproduction, Waiting, Non-utilised talent, Transportation, Inventory, Motion, Extra processing — DOWNTIME.
Pareto Focus
Twelve loss categories, limited effort. Pick the vital few that recover 80% of the loss.
Loss recovered
0 / 612 h
0 of 12 categories selected. The orange line is the 80% target.
