What is a decision table

A decision table is a way of visual mapping of possible flows of some decision, when there are a lot of variable conditions involved. The brain of an ordinary human has a quite narrow focus and we often fall short of keeping track of various combinations of things we are trying to form our decision for. The usage of decision table may help in visualising, not missing and organizing all possible variants of something complex you are trying to get a grasp on.

The decision tables are mostly used by business analysts, developers, and philosophers. But once you know how helpful this method could be, you start to use it in everyday life: from deciding when should you go for a milk, to understanding how to act in complex life situations.

Just write down all available variants in a few lines and put your opinion right next to each one - you have your first decision table. This works terrific when dealing with a few choises, but becomes unberable having a lot of them. This is when automated decision table software becomes really useful.
