Previous: A Brief History of Business Analytics (Part 4 of 8)


Decision Support Systems (DSS) came about in the 1960s by combining BI concepts with OR/MS models to create computer systems that support decision making (Wikipedia, 2018e).

These are some of the traits of DSSs:

1. DSS is meant mainly for upper level managers, who typically face less structured and not-so-specific problems.

2. Since they are built for upper level managers, DSS focuses on features which make them easy to use by non-computer-proficient people; in an interactive mode.

3. DSS allows for flexibility, accommodating changes in the environment and decision variables.
