Q. MJMPM Graphite, Inc produces carbon graphite fibre shafts for Calloway golf clubs. Last year their average monthly production included 19,000 shafts using 1 shift of 3 technicians working 20 days a month also 8 hours a day. Of the items produced, 15% were deemed defective also were scrapped due to poor tensile strength of the graphite shaft.
Recently, MJMPM Graphite, Inc took your recommendations to revise the process by reorientation the fibre layup prior to the production method. Your process needs an additional technician working 20 days a month on an 8 hour shift to monitor the orientation of the fibbers as they are compacted on a mandrill to Estimate the resistance to torsion. As a result, monthly production has increased to 24,000 units with defects reduced to 9%.
a. Compute the productivity ratios for the old also the new production systems.
b. You have to report to the Operations Manager on the impact to productivity of your new process. Elucidate what will you report?
