The five basic logical tools of the Theory of Constraints (TOC) thinking process should be used in the following order: First, understand the current situation using the Current reality tree (3). Next, identify and resolve conflicts with the Conflict resolution diagram (4). Then, envision what the future should be with the Future reality tree (2). Prepare for that future by planning what must be done with the Pre-requisite tree (1).
Finally, execute the change using the Transition tree (5).
