Design

Describe the final design of your interface. Illustrate with screenshots. Point out important design decisions and discuss the design alternatives that you considered. Particularly, discuss design decisions that were motivated by the three evaluations you did (paper prototyping, heuristic evaluation, and user testing).

Home

Originally the home page had a tab in the lower right hand corner that would allow users to cancel a previously scheduled call, but from feedback we found that this wasn't externally consistent with other web pages. Instead we moved this functionality to the page header along with other options. Additionally this allowed the user to access these options regardless of the mode they were in.

Record a voicemail

Because the voicemail recording widget was flash based, it loaded slightly after the rest of the page leaving the user guessing about what to do for a small but still noticeable period of time. We added a loading symbol to account for this. Furthermore, the heuristic evaluation mentioned that users could submit without recording first, so we fixed that as well.

View scheduled calls

This page would not exist without the valuable feedback we got from the heuristic evaluations. Previously users would not be able to see what calls they had and instead had to cancel them from memory, but this page provides much more transparency so that the user is much more in touch with the actual model.

Implementation

Describe the internals of your implementation, but keep the discussion on a high level. Discuss important design decisions you made in the implementation. Also discuss how implementation problems may have affected the usability of your interface.

Evaluation

Describe how you conducted your user test. Describe how you found your users and how representative they are of your target user population (but don't identify your users by name). Describe how the users were briefed and what tasks they performed; if you did a demo for them as part of your briefing, justify that decision. List the usability problems you found, and discuss how you might solve them.

Reflection

Discuss what you learned over the course of the iterative design process. If you did it again, what would you do differently? Focus in this part not on the specific design decisions of your project (which you already discussed in the Design section), but instead on the meta-level decisions about your design process: your risk assessments, your decisions about what features to prototype and which prototype techniques to use, and how you evaluated the results of your observations.
