As Operations Manager, you would like to estimate the cycle time of the manufacturing process.

The developed aortic valve replacement system includes an automatic tip. The tip is molded to the shaft of the delivery catheter system, utilizing an injection-molding process. There are two injection-molding machines available for this operation.

The shafts are being supplied to the injection molding work cell with the rate (i.e., arrival rate) of six (6) shafts per minute.

The injection-molding cell processes the shafts with service rate of four (4) per minute. You are required to estimate the average time that would be required to complete molding operation for the one unit. Set up and solve the problem using Excel QM or POM.
