@firasathsfa: Ah, it sounds like you have a different category of problem, less about the technical aspects and more about people. In my opinion, the absence of Standard Work/WI isn’t a problem statement since there is no “so what” to it. Now, I’ll be the first to tell you that there is almost certainly more variation in your process and op…[Read more]
@firasathsfa: Chris has a great observation here. It may be a bit premature to be concerned about the mechanics of measuring cycle time and determining takt time when there is probably greater value in completing process mapping first and then looking at value stream mapping to get into more of the detail. It’s hard to tell from your brief que…[Read more]
I’ll take your question at face value since I’m new to the discussion.
The USL and LSL are given to you by your customer. These specifications determine the range of variability within which they will accept output variation.
The sigma levels describe how a process performs *with respect to* those limits. It describes how well the p…[Read more]
