When should I use Decision Rules instead of a Decision Tree?

A Decision Rules Object can offer an alternative knowledge representation to Decision Trees if it can be used to more naturally represent the logic used to selecting multiple different outcomes. It is typically suited when implementing a set of simple "checklist-style" rules.

if these rules are implemented using a single (multi-select outcome) Decision Tree instead, it would result in a large and obscure structure (unless Sequence Nodes are used).

Alternatively these rules could be implemented by using a separate Decision Tree Object for each rule which may result less overall transparency.
