With the information available Don can complete the first two steps of TOC as shown below. The analysis shows that the reactor process is the constraint, and that in the short run, Polymer 1 is the most profitable product. The most profitable product mix is 60 units of Polymer 1 and 35 units Polymer 2. Until the production delays can be dealt with (TOC steps 3-5), Don should advise IPC to meet all the sales demand of Polymer 1 and to advise customers of Polymer 2 there would be some delays in the short–term. Then, IPC should work quickly to relieve the constraint, reactor time, by applying the third, fourth and fifth TOC steps. Without specialized technical knowledge of the manufacturing processes in this industry, one can only speculate about what these steps might be
