ASQ is a great place to browse and learn. The link above is a concise write up of the power of a Pareto Chart and how the same can be generated in Excel. You could do it with Minitab as well.

My first brush with a Pareto chart was in 2001

My assignment for the week was to increase the yield of a packaging line with a major manufacturer of diabetes bio-sensors.

I walked the line, talked to the operators and talked to one of the engineers

Here is the low down

  • The operators maintained a very clear record of the down time and frequency
  • The data was collected and stored in a database
Went and met the keeper of the database
He was thrilled and mentioned that he was waiting for the day when some one would come in and ask him for the data.
Got the data plugged it into Excel and created a Pareto Chart.
Passed it around the weekly meeting with a smug look
Here are the top hitters
  • Meetings
  • Repairs to literature folder
Action
  • Have communication on the line and reduce wasteful meetings
  • Bring in the literature folder company rep and recondition the system
ROI or is it Return On No Investment?
  • Increase in yield from 75% to 95%
Is that instant gratification or what?
Well since then I have used the Pareto Chart any number of times with success and little effort
Who needs training courses?
Is that LEAN manufacturing or what?
