C: ensure we are not overlooking the primary issue limiting productivity
D': improve productivity through process improvement with no additional monetary investment
In order to thoughtfully and systematically improve productivity in a fiscally responsible manner we must ensure we have taken all possible actions to improve productivity and in order to ensure we have taken all possible actions to improve productivity we must invest in new ball grinding machines to improve productivity. But, in order to thoughtfully and systematically improve productivity in a fiscally responsible manner we must also ensure we are not overlooking the primary issue limiting productivity and in order to ensure we are not overlooking the primary issue limiting productivity we must improve productivity through process improvement with no additional monetary investment. we can't both invest in new ball grinding machines to improve productivity and improve productivity through process improvement with no additional monetary investment.
| Relation | Assumption(s) | Injection(s) |
| D-D' | the new machines cost money and if the bottle neck moves the capacity of the plant will be limited to a different resource causing the need to spend more money in an endless cycle. | we are able borrow the money to buy the new machines and keep the bottle neck in the lapping work center |
| B-D | the new equipment takes load off of the lapping work centers by eliminating the need for rough lap machines and allows the current rough lap machines to be used for mate lap. | the new machines work on a limited size range and final lap is still needed to complete the process |
| C-D' | the current credit line is tight and we are not confident that the lapping work centers are the bottle neck. We have not considered more ways to off load the bottle neck and have not considered the impact of the bottle moving else-ware. | funding is possible by using a capital loan and the data shows that the bottle will still be in the lapping work center |
| A-B | customers demand a quality product to be delivered on time | the new machines will not be able to accommodate the spikes in demand and do not improve overall quality because final lap is still needed to complete the process |
| A-C | new machines cost money and they do not guarantee that quality and on time shipments will imporve | the new machines get the product to final lap in a state that is easier to mate lap to mandated tolerances which improves efficiency and capacity which means the plant can ship more product making more money that in turn will pay for the additional investment needed to buy the new machines |
