The purpose of this assignment:
Activity design is the first step of the design process under
both SBD (Rosson & Carroll) and UCD (Constantine & Lockwood).
We will try the major techniques of each approaach, to comprare
them and understand their relative merits.
Please do the following:
You should turn this work in as individuals, but may work with
up to 2 other students to discuss the assignment and try the methods
on each other. If you work in a group, do NOT divide up the tasks
such that each student only does part of the work. You should try
ALL techniques as a group, so that everyone has personally been
involved in the application of each technique. Then you can each
modify the group work as you wish and prepare your individual presentation
of that work.
-
Read chapter 3 of Rosson & Carroll, Ch. 5 of Constantine
& Lockwood, and the online paper Constantine
& Lockwood (2000): Structure and Style in Use Cases
for User Interface Design. (All of their online papers are of
high quality and go beyond the thinking in their book.)
- Using the requirements analysis that you did for Assignment
2, do the following for the Collaborative Calendars application:
- Metaphors:
- Identify two metaphors for collaborative calendaring
and write a few implications of each metaphor (see page
93 of Rosson & Carroll).
- Activity Scenario and Claims Analysis:
- Write two scenarios of your system being used
- Derive from these scenarios a claims chart that shows
the features you propose to include in the solution and
their positive and negative aspects.
- Task Model in Essential Use Cases
- Write at least two essential use cases to capture the
kind of activity you want to be able to support.
Be careful to abstract away from implementation decisions
in the Activity Scenario and Essential Use Cases.
Also,
why did this step start out in boldface red font? Because
you should build on your prior work. It does not make
any sense to do some requirements or design work and then
ignore it!
- Make a web page that tells the story of your activity design
and includes all of the documents you created. Write
a page (paragraph or two) summarizing your view of the utility
of the methods, and how they might profitably be combined together
on future projects.
Please make this a different web
page than the one for Assignment 2. We don't want to have
too much on a page. However, your Assignment 3 pages should
have a link to your Assignment 2 page so we can see how
the two relate.
- Submit your assignment in disCourse (the URL of your
page will be the artifact).
- Comment on the most recent submission.
