Lean 6 Sigma: proving root cause of failure in mining to guarantee improvement
Identify possible causes.
Identify all the likely causes of the problem (e.g. poor rock fragmentation) and rank them in sequence of likelihood.
Relate causes to the problem.
Gather data about the most likely causes (e.g. rainfall, poor drilling to plan, incorrect hole depths, etc), and use it to compare to the problem.
'Prove' causes using simple statistical methods.
Correlate the 'hypothesised' causes to the problem to identify and demonstrate causal linkage. Acting on proven causal links guarantees significant improvement.
6 Sigma lets us find the root causes of problems and fix them, ... permanently.A.F. Supervisor
I can see now why the focus in 6 Sigma is about using data. This has helped us find the cause of a problem that would have taken ages to find otherwise, and has dogged us for years!H.d.B. Head Of Engineering
