Challenges with the Solver? (Open Comments) 24 Responses “ Being able to explain why the solver gave  Complexity (9) certain results vs. the expected results” “ Updated training materials ”  Training and Experience (5) “ lack of training ”  Visualization (3) “GUI is hard to read”  Effectiveness (2) “some reports show massive amount of data that is not relevant”  Other (5) “Lack of Excel functionality for input reports (copy/paste)” 7

Data Visualization To convey information through graphical representations of data The understanding of, support for, and communication around the Solver is very high; Current processes should stay in effect with only minor changes. Initial and version-update user training should be robust and application-oriented MIT SCM ResearchFest 8 May 22-23, 2013

…not just a software tool “clutter & confusion are not attributes of information, they are failures of design” E. Tufte The understanding of, support for, and communication around the Solver is very high; Current processes should stay in effect with only minor changes. Initial and version-update user training should be robust and application-oriented 9

…but software can help The understanding of, support for, and communication around the Solver is very high; Current processes should stay in effect with only minor changes. Initial and version-update user training should be robust and application-oriented 10
