Problem-Solving from 0 to 8:
Level 0 — Can’t see the problem
Level 1 — See the problem and raise it
Level 2 — See the problem and define it clearly (a problem well defined is a problem half solved)
Level 3 — See the problem, define it clearly and identify the root cause
Level 4 — Plan ahead to avoid the problem or derivative problems re-occurring (prevention is better than a cure)
Level 5 — Find a practical and viable solution to the problem
Level 6 — Find a breakthrough solution to the problem (for example one that saves more than it costs, or opens the way to other breakthroughs)
Level 7 — Take initiative to implement the solution or develop the breakthrough
Level 8 — Look beyond problem prevention — create new opportunities from continuous improvement …
