INFS 720 – Systems Analysis and Design Assignment 06
Page 1 of 2
The context is the Internship Application (automated presentation scheduling, evaluation and feedback).
Recall that preconditions are assumed to be true so do not include any information in your sequence
diagrams to support the pre-conditions (to be clear, do not bother with login interactions). Also, to
simplify the exercise, do not include the alternative or exception flows. Just focus on the normal flow.
Based on the UC-3 Configure Schedule use case below, create a UML sequence diagram and associated
UML class diagram. Be sure to include properly named messages, parameters and if appropriate,
relevant return information.
Annotate your sequence diagram decisions with “by xxxxx” notations indicating how you applied the
initial 5 GRASP principles to your design. See figure 17.4 where the author notes, “by Creator” as an
example and the presentation slides.
Use Lucidchart or similar program to create your diagrams and save them in PDF document. Submit the
PDF files to D2L.
