    Hi

    I ran a pareto chart analysis that showed the most important factors over a date range for each die …This was a die performance review in the plastics extrusion process… What the problem was the hopper clogging material,barrel/extruder problem and other problems… The Pareto chart analysis gave an insight of increase in setup time hangup time as well as increase in scrap time …These were the critical factors that needed to be focussed on…At the next stage I am confused what to do, how to proceed further….Should I run a cause and effect analysis diagram or conduct a DOE study to work on determining the factors that are causing the problems…like running a pre test experiment or a rough one and find out……  PLEASE ADVISE……..
    Thanks
