In an effort to evaluate performance and determine where improvements can be made, management has gathered the following data

relating to activities over the last four months:

The president has read in industry journals that throughput time, MCE, and delivery cycle time are important measures of performance,

but no one is sure how they are computed. You have been asked to assist the company, and you have gathered the following data

relating to these measures:

Required:

$1-$a$.$ Compute the throughput time for each month.

$1-$b$.$ Compute the manufacturing cycle efficiency $($MCE$)$ for each month.

$1-$c$.$ Compute the delivery cycle time for each month.

$3-$a$.$ Refer to the inspection time, process time, and so forth, given for month $4.$ Assume that in month $5$ the inspection time, process

time, and so forth, are the same as for month $4,$ except that the company is able to completely eliminate the queue time during

production using Lean Production. Compute the new throughput time and MCE.

$3-$b$.$ Refer to the inspection time, process time, and so forth, given for month $4.$ Assume that in month $6$ the inspection time, process

time, and so forth, are the same as in month $4,$ except that the company is able to eliminate both the queue time during production

and the inspection time using Lean Production. Compute the new throughput time and MCE.
