Question：Systems pool data from internal and external sources and make information available to senior managers, for strategic, unstructured decision-making.
Which word or phrase correctly completes this sentence?
A. Decision Support
B. Executive Support
C. Management Support
D. Expert
The correct answer is: Executive Support
Rationale: This is the definition of an Expert System. It is distinguished from a DSS by supporting decision-making at a higher and less structured level. Expert systems draw on a knowledge base to solve well-defined technical problems.
Pitfalls:'Management', 'Expert' and 'Decision' were plausible distractors: make sure you can distinguish between the different types of system, and how they contribute to decision-making and problem solving.
