MCE, Lean Measures, and the Balanced Scorecard
Numark, Inc., manufactures a product that experiences the following activities and times (the production processes are listed in sequential order):
| Minutes | |
|---|---|
| Cutting | 20 |
| Welding | 15 |
| Assembly | 7 |
| Polishing | 3 |
| Moving (three moves) | 12 |
| Waiting | 18 |
Required:
Compute the time required to produce one unit of product under the current production layout.

Required:
Assume that Numark creates a manufacturing cell that eliminates move and wait times. What is the production rate assuming continuous production?
MCE, Lean Measures, and the Balanced Scorecard

| Cutting | 20 |
| Welding | 15 |
| Assembly | 7 |
| Polishing | 3 |
| Moving (three moves) | 12 |
| Waiting | 18 |
Required:
If the time for the cutting operation is cut in half, what effect will this have on the production rate?
| Time(in minutes) | |
| Cutting | 20 |
| Welding | 15 |
| Assembly | 7 |
| Polishing | 3 |
| Moving(3moves x 12min/move) | 36 |
| Waiting | 18 |
| TOTAL PRODUCTION TIME | 99 |
Just add all. Note also that I assume that moving is 12 minutes per move.
99 minutes or 1 hour and 39minutes
To get the production rate we divide the number of products produced by the time taken to produce the products. The amount spent on the creation of a single product above is gotten by adding the time taken on all the processes. Since the company opted to eliminate 2 processes, the time spent on those processes is eliminated hence the production rate the was initially 1 product per 75 minutes is reduced to 1 product per 45 minutes.
1 product per 45 minutes
Cutting the cut operation by half, we will have the welding as the slowest operation;
Production rate=60/15=4 units per hour.
Solution
The new production rate will increase to 4 units per hour.
