three-cloud approach​

three-cloud approach - A relatively fast method of developing a current reality tree (CRT) wherein the developer identifies three seemingly independent undesirable effects (UDEs), creates an evaporating cloud (EC) for each, and synthesizes the three ECs into a single generic cloud called the core conflict cloud (CCC).

Usage: The three-cloud approach uses assumptions underlying each of the entity pair relationships (A-B, A-C, B-D, C-D' and D-D') in the CCC together with the CCC itself to form the base for a CRT by: 1. rotating the CCC 90 degrees counter-clockwise, 2. modifying the wording of the entities slightly, 3. reversing the direction of the arrows, 4. adding any necessary assumptions to provide sufficiency to the logic, 5. including transitional, fact-of-life entities as necessary, and 6. building upward to the UDEs for the system being analyzed.

Illustration: The base of a CRT created using the three-cloud approach is shown below:

Caution: Some critics feel that using the three cloud approach may not lead to a core problem while other feel that this criticism is overcome by the proper selection of UDEs (from diverse functions).
