There are only 2 possible causes for #RootCauseAnalysis and it’s very close to #TWI from #Lean

May 3rd, 2018 Posted in Lean Tags: , , , , , , , ,

A friend of mine just reported a very interesting insight from a meeting he had with the japanese man (sorry didn’t took note of his name) who invented QRQC or Quality Circles. I’m posting this here as the guy doesn’t have a blog of his own.

The two possible root causes are:

  • failure to instruct properly, which is what TWI Job Instruction is about
  • failure to setup your process properly, which at first the japanese man presented as a bad FMEA.

And what’s in a FMEA? 1) Overall steps of a process 2) Key points and 3) risk analysis

Can you see how close this is to a TWI Job Breakdown Sheet with the 1) steps 2) key points and 3) justifications of the key points (where the justification is a risk mitigation technique in itself to ensure memorization of the key points)?

So basically, you end up with the only two possible root causes of any problem :

  • bad Job Breakdown Sheet (description and organization of the job)
  • bad Job Instruction (instruction of that job)
