Compressing Decision Tables                                                                                 Solutions

In this case, the right table will produce the same results as the left one. However, when a decision table includes much more attributes (columns), the manual analysis becomes difficult or impossible even if you allow a certain level of unsuccessful results. In most cases, you need some special tools provided by digital decisioning products.
