When you are solving a Linear Programming problem using the Theory of Constraints, you should:

Identify the bottlenecks that constraint the system and maximize the production of products that have highest revenue per hour in the bottleneck.

Identify the bottlenecks that constraint the system and maximize the production of products that have the highest profit margin.

Always increase the number of variables to ensure a more comprehensive solution.

Ignore the constraints and focus on maximizing the objective function.
