Decision Tables and Dependency Diagrams
An expert system is used to determine whether the recommended entry strategy into international markets should be Investment (I), Contractual (C), or Export (E).
This recommendation is based on internal factors as well as external factors. Both internal and external factors are rated as Strong (S), Average (A), or Weak (W).
As long as the external factors are weak the recommended strategy is export. As long as the external factors are strong the recommended strategy is investment. When the external factors are average the strategy should be Export if the internal factors are weak but contractual otherwise.
1. Represent the above decision situation as a decision table.
Simplify the table as much as possible
2. Express the results of the above decision table as IF ... THEN Rules. Avoid using ELSE statements. The outcome should not be affected by the ordering of the rules.
External Factors are determined by Foreign Country factors (S/A/W) and Home Country Factors (S/A/W). External factors are considered strong if both Foreign and Home Country factors are strong. If Foreign Country factor is weak then External Factor is considered weak. Otherwise External Factor is considered average.
