Joseph,
The "temporary bottleneck" must be exploited to avoid impacting the real bottleneck. But if it is not a bottleneck then exploiting it will waste your time.
The bottleneck should show up on your CRT. If not then the CRT is not correctly represented your plant situation.
This can be caused by:
Let go back and do some CLR and perhalf come up with different set of UDEs.
Let me ask you this:
What is your T, I, and OE?
The UDEs should related to T, I and OE. Let say your
T = number of chair produced
And let assume that you produce 100 chairs/week
then the question is why can't you produce 200 chairs/week? What is stoping you from doing that? What are the UDEs which prevent you from doing that?
Think backward from the manufacturing output to assembly line to QA to part, material, order, shipping, marketing .... to the beginning of the customer place an order.
I suspect that the bottleneck or core problem are some where in the manufacturing line.
Remember that once the Core problem is found then the opposite of the core problem will be the objective of the Evaporating cloud (EC)
>From looking at your trees, I feel that these are long term problems. Not that they are not valid, but the trees need to be clear and all the arrow should not be LONG arrow.
Once the bottleneck is found I think DBR should be implemented to buffer the bottleneck.
The best way to learn more about using TOC in production is to use Production the TOC Way: Self-Learning Kit, you can read about it at:

Your are right, TOC and MRPII, From Theory to Results article moved, I found it using search engine. It is at:
