One of the Thinking Processes in the Theory of Constraints, a Current Reality Tree (CRT) is a way of analyzing many system or organizational problems at once. By identifying root causes common to most or all of the problems, the CRT can greatly aid focused improvement of the system.

Simplified explanation

One of the first steps in this process is to describe, in a simple visual drawing, the main perceived symptoms (along with secondary/hidden ones that lead up to the perceived symptom(s)) of a problem scenario and ultimately the apparent cause for the problem or conflict. The benefit of doing this is that it much easier to identify the connections or dependencies between these. Thus, focus can be placed on the bits which would cause the biggest positive change if tackled.

Contextual explanation

A current reality tree is a statement of an underlying core problem and the symptoms that arise from it. It maps out a sequence of cause and effect from the core problem to the symptoms. Most of the symptoms will arise from the one core problem or a core conflict. Remove the core problem and we may well be able to remove each of the symptoms as well. Operationally we work backwards from the apparent undesirable effects or symptoms to uncover or discover the underlying core cause.
