Rationale & Justification  Context of your work  The following are good examples from student work for Deliverable 1 –Rationale –Citations –Justification

Design Activity  User Information –Problems with any of the different systems operating behind the scenes are perceived as problems with the primary application –25% of feedback received was not categorized by the user and another 26% was categorized as “Other Problem” –Feedback does not always pertain to the page that the user is on when they click the Feedback link –Some people enter sensitive information

Design Activity  Requirements –Keep it simple to provide feedback –Provide acknowledgement and confirmation  The system is working properly at the time they submit feedback  A message containing the text of their feedback –Preserve the ability to remain anonymous  Offer a means of providing candid feedback without fear of repercussion –Commitment of 2 business days for a response –Urgent matters should be directed to the help desk –People can change their address

Design Activity Design Activity  Redesign the Feedback page  Document –Rationale to support design decisions (explicit) –Trade-offs

Project Sharing  Team discussions –Share results of usability testing –Discuss your choice of methods and results  Class-level discussion –Each spokesperson share  One challenge  One surprise  One lesson learned  Paper Prototyping in the Street

Discussion of Readings  Insights from supplemental readings.  Facilitate class discussion of topics / ideas / themes garnered from the online discussion, related to assigned readings. –Discussion Leaders 1. Rob MacDonald 2. Sammy Woogerd 3. Tiffany Fehr

Topic I: Presenting solutions in the context of user-centered design Arguing for UCD Driving Questions:  What challenges and complexities are associated with UCD in the “real” world? How does this affect how you talk about user-centered design processes and proposed solutions?  What are contexts in which you might be asked to engage in user-centered design activities? What strategies can one use in order to persuade and/or convince others to engage in user- centered design activities?

Cost-Justifying Usability  Reluctance – even with low-cost methods  Costs 100 times more to make a change in the next release (Nielsen)  How much is lost when employees can’t use products efficiently and effectively? –Search button –Enter key to invoke Search –Web-based tab menus –Expense reporting  Cost of frustration and dissatisfaction???

Cost-Justifying Usability  Measures –Training time –Task time/Workload capacity –Error rate –Time to recover –Help desk/Tech support –Helping coworkers (OJT) –Revenue –Projections  Cost of NOT testing  Benefits of testing

Discussion  What challenges and complexities are associated with UCD in the “real” world? –What similarities? –What differences? –What surprises? –What implications? –What makes it hard? –What constitutes success of UCD? –Where can you be flexible? –Where do you have to stand firm? –What options do you have for applying and adapting UCD methods? –Note: Hackos & Redish, pp , for good examples of the benefits of site visits

Project Deliverable 2 Solution Recommendation  In this report, students will present their final solution along with their justification of that solution.  Project deliverables are due at the beginning of class.  Bring copies of the deliverable to class (one copy for the instructor) and also post it to your design portfolio.  Due next Thursday

Looking back / Looking ahead Where we’ve been  Topics – Readings and discussion –What is UCD? –Collecting and summarizing info about users, tasks and context –Problem definition –Design –Evaluations  Project –Insights about users, tasks, and contextual issues –Actual data from observing real users –Problem definition –Proposal –Design –Evaluation (heuristic & usability) Where we’re going  Revisiting UCD: –Challenges –What supports UCD?  Readings: –Usability vs. Testing vs. UCD –UCD processes & ISO (Supp) –Key principles of UCD  Upcoming Work: –Solution Recommendation –Final Exam  Issue Statement: A reminder 1.
