CS 350 – Computer/Human Interaction
Fall 2006 – Homework 1
20 points
Out: September 6
Due: September 8, at the beginning of class, no late work

Go to the Usability Case Study website at http://ucs.ist.psu.edu. This is a website maintained by the textbook authors and contains (mostly) real world examples of using SBD to design user interfaces. Click on the Case Studies tab in the left column and visit the Garden-com case study.

Do the following:

• Skim all of the Requirements Analysis portion of the case study.

• Study the Problem Scenarios and Problem Claims (under the Synthesis tab) of the case study

• Write another problem scenario that illustrates something different in the problem domain and write a problem claim that arises from the scenario. You may add additional stakeholders, if you also provide sufficient background for them in the scenario.

There is no “right” answer for this assignment, but your scenario and claim should follow the general format and level of detail of the case study and examples in Chapter 2.

On Friday, we will discuss the case study and compare scenarios and claims in class.
