A Future Reality Tree (FRT), as the name suggests is a visualization of a desired, improved future state. It answers the question “What to change?” Or “change to what?”. The Future Reality Tree is one of the Thinking Processes or Thinking Process tools.
Thus the FRT turns the Undesirable Effects (UDEs) identified with the CRT into Desirable Effects (DEs) by combining the real causes of UDEs with injections, which are entities (actions or conditions) that do not yet exist, but which are necessary to correct the current state, turning it into desirable future condition or target.
Injections are a cure to Undesirable Effects when combined to the cause of UDEs. Injections are always entry points (they do not have a cause) and are distinguished from others entities by their square corners.
A FRT is recognizable by the basic structure of a cause AND an injection linking to a Desirable Effect. In the example below (French) the injections are lined in blue in order to highlight them. Numbered entities are UDEs from the Current Reality Tree.
In this FRT, two injections create positive reinforcement loops (right side).
A Future Reality Tree depicts the could-be future, but does not give all the answers about how to get there, how to close the gap between the Current Reality and the Future Reality. Therefore, two more tools or processes are provided: the Prerequisite Tree (PRT) and Transition Tree (TT).
