SIX SIGMA CASE STUDY TO REDUCE LEAKERS
We were tasked with reducing the amount of “Leakers” on a Bartelt Line producing Pistachios using the Six Sigma Definition: Six Sigma is a set of techniques and t...

First we completed a SIPOC to determine if their were any inputs external to the Process that could be an issue. We found that variation in the film could be a contributing An input variable being studied in an experiment or ANOVA..
We then defined the X’s in the process. This is where we “look for open windows” (can the process meet it’s existing tolerances). We found that there was no data being catalogued for the measurable and controllable inputs. We also found that the output was measured in Pass/Fail rather than a continuous metric.
We found that the KPOV’s were the position of the heat placement and the dwell time. We took capability measurements after completing a controlled setup and implementing some poka-yokes, and the short term capability increased to over 2.
