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)

 

 

Advantages of using #TWI Job Instructions from @TheBilasGroup

I was searching for these in the TWI materials, and found this excellent, exhaustive list of TWI JIT advantages from The Bilas Group.

Nothing else to do. If you ever need to give arguments to a CEO about deploying JIT (Job Instructions Training), this is the list to use.

Besides, you’d better know your Management Contact Manual as well!
