Process for Developing Prime Decision Tables

A problem expressed as a decision table is presented to a processor.

The processor examines the entries in the table, rule by rule, taking all possible combinations of 2 rules at a time.

If the entries in the table rule pair show that the action sequence is equal (1,2 is equal to 3,5 in this case), the exits for the rules are equal, the non-used actions are equal, and the rules differ in exactly one condition entry with a "don't care", then the "don't care" is changed to a Y or N to make it unique.

The result is a table with a minimum (prime) specification which has the attribute that code generated from it will be minimal.
