11)Extreme Wreaths, Inc. makes wreaths in batch sizes of 15 at a time. The cutting & assembly process takes 10 minutes per wreath, and the decorating process time is 7 minutes per wreath. It takes 5 minutes to move the wreaths from the cutting & assembly process to the decorating process.

In a effort to improve the lead time, the company has tried reducing the batch size to 10 units. The new process is as follows: cutting & assembly process - 8 minutes. The decorating process is still 7 minutes per wreath. It takes 5 minutes to move the wreaths from the cutting & assembly process to the decorating process.

a. Compute the value-added, non-value-added, and the total lead time of the wreath process for both the old and the new manufacturing process.

	Old process	New process
Value-added lead time
Non-value-added lead time:
Move time
Within batch wait time
Total lead time

b. Compute the value-added ratio for both the old and new process. Round to one decimal place.

	Old process	New process
Value-Added Ratio	%	%
