Current Reality Tree

A useful tool that Goldratt uses to identify bottlenecks is the Current Reality Tree (CRT).
Similar to a Root Cause Analysis, 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.

In practice, it helps to combine RCA with current reality. We can start with RCA by focusing on the symptoms and drilling down to the core problem using techniques like 5 whys. From any level of the drill down, we can look at other effects of the identified cause. If they are important, we include them in our current focus. This back & forth movement between cause & effect along with branching out helps a lot to get better picture of the problem domain.
