The TOC methods to bring desired improvements are developed through answering three questions:

  1. What to change?

  2. What to change to?

  3. How to cause the change?


The three important tools are

  1. The Cloud

  2. The Branch

  3. The Ambitious Target Tree

The Cloud is used to resolve conflicts. The Branch is used to show logical consequences of a decision. The Ambitious Target Tree (ATT) is used for problem solving.

The Branch is also called by other names such as a Current Reality Tree (CRT), Future Reality Tree (FRT) or Transition Tree(TrT) depending on the context.

The Ambitious Target Tree (ATT) is sometimes called a Prerequisite Tree (PrT.)
