Alex vs Stacey: Cutting the Batch Sizes
B: decrease the lead time to process a batch and speed up order for customer
D: cut the batch sizes in half on the bottleneck machine
A: increase the sales of the company
Click on the icons on the arrows to see assumptions and injections
C: keep the bottleneck as efficient as possible
D': not cut the batch sizes in half on the bottleneck machine
In order to increase the sales of the company I must decrease the lead time to process a batch and speed up order for customer and in order to decrease the lead time to process a batch and speed up order for customer I must cut the batch sizes in half on the bottleneck machine . But, in order to increase the sales of the company I must also keep the bottleneck as efficient as possible and in order to keep the bottleneck as efficient as possible I must not cut the batch sizes in half on the bottleneck machine . I can't both cut the batch sizes in half on the bottleneck machine and not cut the batch sizes in half on the bottleneck machine .
| Relation | Assumption(s) | Injection(s) |
| D-D' | there is only one batch size on the bottleneck machine | they can not do both ways, they should stay with the one that create an improvement |
| B-D | 1.) that would improve the issue of cash flow | cash will go be tied up to other things other hand inventory |
| C-D' | 1.) there will be less set ups 2.) machine is not going to work at his full capacity 3.) employees will not produce as much as they should | if they spend more time working and the machine work more time, then they will not produce more and the capacity will be higher |
| A-B | 1.)we need to create customer satisfaction 2.)we need to improve cash flow | |
| A-C | 1.) Machines sitting idle do not make money 2.) Employees sitting idle do not make money | you would probably need half the investment in work in process to keep the plan running as efficient as possible |
