    What 6Sigma tools would you use to improve a process where there was not much repetitive action. The data and cycle times are extremely subjective, because it heavily involves human factors. I manage quality of a fleet of mechanics. We have time buffers that incorporate VOC,  but because our clients don’t have specific maintenance requests we never know the extent of the project. This is determined after we inspect the equipment.
    How do you apply 6Sigma to improve a process that does not have hard measurable data?

    That depends.  What part of the process are you trying to improve?  time reduction on repairs?  Overall customer satisfaction?  ellimination of repetative repairs?

    Yes, mainly cycle time on repairs. Overall customer satifacton will comw when we do that.

      Break your repair times down into elements.  IE diagnose, get repair parts, remove part A, remove part B, make specific repair, replace part B, replace part A then look for common steps in each repair, and reduce the variation in those?

    That’s what I thought. But that sounds more like lean principles that 6sigma. What tool to measure variation though?

    It probably is going to be as much or more lean than it is Six Sigma.  But that doesn’t mean you can’t use the Six Sigma tools to help the Lean process.  And possibly during your cause and effect you may turn something up that it will take Six Sigma to fix.  But be careful, we’re starting into a topic that has caused a lot of discussion here at isixsigma when we start talking about the mixing of the two.
