Assertion (A) : User interface is most critical task in DSS design Reason (R) : DSS is used by outside Customers frequently.
(A) is correct, but (R) is wrong.
A decision support system (DSS) has three parts: a database, a model base and a user interface (dialogue management) subsystem.
Assertion: a DSS is used interactively by managers, often non-technical, to explore semi-structured problems. If the dialogue is hard to use, the system is not used at all, so the user interface is regarded as the most critical part of DSS design. The Assertion is correct.
Reason: a DSS is an internal tool built for the organisation's own managers and analysts; it is not meant to be used frequently by outside customers. The Reason is wrong.
Hence, (A) is correct, but (R) is wrong.
