Month

Management would like to know the company's throughput time, manufacturing cycle efficiency, and delivery cycle time. The data to compute these measures have been gathered and appear below:

Month

       

Refer to the move time, process time, and so forth, given for month 4. Assume that in month 5 the move time, process time, and so forth, are the same as for month 4, except that through the implementation of Lean Production, the company is able to completely eliminate the queue time during production in month 6 the move time, process time, and so forth, are the same as for month 5, except that the company is able to completely eliminate the inspection time. Compute the new throughput time and MCE. (Round your answers to 1 decimal place.)
