Decision Tables
• A table of rows and columns, separated into four quadrants• Conditions• Condition alternatives• Actions to be taken• Rules for executing the actions

Developing Decision Tables
• Determine conditions that affect the decision• Determine possible actions that can be taken• Determine condition alternatives for each
condition• Calculate the maximum number of columns in
the decision table• Fill in the condition alternatives• Complete table by inserting an X where rules
suggest actions• Combine rules where it is apparent • Check for impossible situations• Rearrange to make more understandable

Checking for Completeness and Accuracy
• Four main problems• Incompleteness• Impossible situations• Contradictions• Redundancy
