The Goal-Finding Herbie
B: Find the constraints
D: Look through data
A: Find Herbie
| A-B: | Assumption(s) | Injection(s) |
| This will lead to where the conflict occurs |
C: Find piles of inventory
D': Take a walk through the plant
In order to Find Herbie I must Find the constraints and in order to Find the constraints I must Look through data. But, in order to Find Herbie I must also Find piles of inventory and in order to Find piles of inventory I must Take a walk through the plant. I can't both Look through data and Take a walk through the plant.
| Relation | Assumption(s) | Injection(s) |
| D-D' | I cannot do two things at once Seeing piles of inventory is easier than evaluating data | Walking through the plant with the data |
| B-D | SF (statistical fluctuations) will be created after talking to Pete | Subordinate the non constraints |
| C-D' | This will reinforce the SF after looking through data | Create a tag system for the constraints |
| A-B | This will lead to where the conflict occurs | |
| A-C | These machines become bottlenecks; which are holding up the process of orders shipping out |
