Future Reality Tree (FRT)

Solution validation (ToC), showing how proposed solutions lead to desired outcomes. The same node types as CRT, both being sufficient-cause Theory of Constraints tools. The difference is use: FRT starts from solutions (Changeable injections) and builds upward to desirable effects.

Node types

• Changeable — proposed solutions or injections to implement
• Given — unchangeable facts that still apply
• IntermediateEffect — expected intermediate outcomes
• DesirableEffect — goals we want to achieve
• UndesirableEffect — potential negative side effects to monitor
• AndJunctor — as in CRT

Edge types — the CRT family, shared by CRT, FRT and TRT; see Current Reality Tree.
