4.  Because decision-making involves a complex sequence of activities
over time, it implies there are at least three functions that should be
assigned to DSSs:
1. The capability of capturing and saving information from previous
activities.
2. Data processing capability.
3. Data retrieval capability.

13.  DSS can be extremely beneficial to any organization’s overall
performance.
 However, DSS can also be the cause of great confusion, misperception
and even inaccurate analysis – these systems are not designed to
eliminate “bad” decisions.
 DSS are there to facilitate a manager in making operational decisions.
