Management has identified some important areas for improvement in a continuous production unit, including yields, costs, efficiencies, scrap, and rework. A number of process changes have been proposed to address these areas, including new mixing procedures, alternative flow control, and changes in the catalyst operation

(catalyst type, amount of charge, frequency of catalyst charge). The previous studies of these alternatives have not yielded clear results because of different operating procedures between the shifts. Also, the ambient weather conditions can have a big effect on the performance of the process. Plan an experiment to improve this process. Complete an experimental design planning form for the study (it is not necessary to complete the design matrix or data collection form for the study). What other important information needs to be determined before planning the study? Use your imagination to fill in these details.
