Design Documentation : AAU Student Self Service Web Application

The AAU Student Self Service web site is a tool accessed by all registered students of Academy of Art University to perform administrative tasks to their student account including registering for classes, updating student profile, keeping up to date with Financial Aid and tuition payments. The contents of this document illustrate our proposed solutions for the design and development of the AAU Student Self Service web site. The process by which these solutions were developed are briefly summarized in the following pages.

The most successful web sites are those that not only respond to user feedback, but actively seek it out. - Jennifer Fleming (1)

REQUIREMENTS ANALYSIS

This section presents the summary of results of the Requirements Analysis to identify target user requirements for the AAU student self service web application.

..... The answer lies with your site’s users.

Methodology

- Jennifer Fleming (1)

One-on-One Interviews Structured discussions with 6 randomly selected students were conducted with the aim of determining how frequently the students used the self service web application, what their goals were that lead them to use the application as well as what kind of hardware and software they used to access the application. 3 interviews were selected to create user scenarios based on their responses. Online Survey Interviewing 6 users was not enough to gain representative information about our users, so we setup an online survey to broaden our scope of findings. The survey addressed three areas of interest: demographics of user, prioritization of user requirements, and use of particular hardware and software. General Research To augment our findings through interviews and surveys, we also researched web sources for student demographics as well as contacted Bill Cash, the Director of Institutional Research for the Academy of Art University. Stakeholder, Situation, Need, & Feature (SSNiF) Analysis In order to better understand user needs and what features should be developed in a web application to meet these user needs, we also developed a SSNiF Analysis which described possible scenarios users could find themselves faced with and answered how these needs would best be met.

If you ignore some stakeholders, someday they’re going to walk in and play their trump card, and an otherwise careful design will be shot full of holes.

REQUIREMENTS ANALYSIS (cont.) Overall Web Site Objectives

To provide students with an administrative web portal where they have direct access to their personal and academic account and can make modifications to this account when and where it suites them. Also, to relieve the school’s financial burden of hiring a staff to otherwise provide this required service to the students. • A coherent structure that requires little learning time and immune to user error (especially when handling a student’s finances). • User must be able to access all high-level administrative features in 3 clicks or less. • User must be able to access all main information categories via a main navigation system consistently found on every page within application. • The web application must perform optimally for 95% of users and sufficiently for 100% of users. • 75% of users must rate the system as being very responsive, 95% reasonably responsive. • 95% of users must rate the content as being relevant and informative. • 90% of users must rate the system as being easy to use. • System efficiency and usefulness should be rated higher than the attractiveness of the application, although 75% of users should rate it as being visually appealing. • First time users will be able to find the desired feature within two minutes of visiting the web site; expert users or users who have used the site five or more times, should be able to find a desired feature within 30 seconds. • Users will be able to search the web applications’ features with ease.

USABILITY TESTING In order to subjectively evaluate the usability of our designs, we developed an HTML prototype featuring 5 common tasks the user would be required to perform. The success of the proposed design would be determined by comparing user feedback to the site’s defined usability objectives (listed on page 6 of this document). This section describes the testing process, information about the test users, user recommendations and our observations and how these findings were incorporated into our final design proposal. Two designs were developed and tested: • Design A focuses on a flexible interface which can be customized by the user to best fit their needs and usage patterns. • Design B focuses on the development of a comprehensive, static interface that allows the user access to all available features, but without overwhelming the user with too many options and keeping the task at hand in focus.

Methodology

For the usability testing, eight participants matching the user profiles, spent 30 minutes each to test the site by completing five common tasks based on real-world user scenarios. During this time, participants: 1. Performed each task on the site while thinking aloud 2. Completed a user background questionnaire 3. Answered questions about overall site impressions 4. Rated the design given various criteria 5. Completed an icon recognition form The only method of recording observations was by the facilitator and observer taking down notes. We did not use any video or sound recording for this user testing session.

Tasks Used for Testing

1. Logging into AAU Student Self Service web site 2. View and email grades 3. Make a payment 4. Enroll in classes 5. Add an event to the calendar

Summary of User Testing

The users testing result indicated that the site had 2 critical, 1 medium and 1 minor issue. Critical issues where mainly for those users who were not familiar with the use of widgets, and the second critical issue stated that the information displayed on the content pages was unclear, specially those in the enroll for classes task. The issues labeled as medium were relevant to the navigation in the content pages, specifically the next and previous buttons. And finally the minor problem was the confusion of some users with the labels of some buttons. In order to fix these issues the following corrections where made.

Summary of User Testing

The user testing brought to light 2 critical, 4 medium, and 5 minor errors in this design option. All critical issues have been resolved in this proposed design as well as three of the four medium level issues. Only three of the five minor problems were addressed, the other two were considered preferential statement by a single user and the other the cohesiveness of the design would have suffered in accommodating the change. The two critical issue addressed in this redesign was: first, the development of a designated Home page rather then opening up the landing page of the first tab, and second, addressing the recognizability of the icons. The following pages illustrate the layout and functionality of the design solution in its final proposed state.

Home Page: A designated home page begins by stating the purpose and capabilities of the site and displays a list of all top and second level links, providing the user a clear scope of the web site. The icon navigation bar has been expanded to display a link title, addressing the potential issue of the user not recognizing an icon’s image or purpose and clearly establishes the association that the icons are buttons.

Icon Portal Page: Another measure taken to assure that icons are recognizable is the inclusion of an Icon Portal page which can be accessed by all pages of the site by clicking the red triangle at the top of the icon navigation bar.

2

Each icon is clearly defined with a link title as well as additional text below the link title that describes the relevant features associated with an icon.

3

Originally, the cyan elements in the icons to the right were red, but users commented that this was distracting them from the main task at hand. To add visual interest to the layout and to emphasize the main focus of this page, the larger icons in the main content area use the red instead of the cyan.

CONCLUSION “Make usability part of everything you do... Living within these eleven words is the most important message any web designer should follow. That is that web sites are constructed for people. And not just any kind of people but a vast array of cultures, lives, experiences and ways of looking at the world. This variety of users are nearly impossible to narrow in on in order to make everyone content and happy. Its at this point that a method focuses in on usability and the way users interact with the design such as the Pervasive Usability Process became the ideal way not only to work for the user, but with them. As a first and vital part of this process the project focused on finding out who the site is for, and based on that data established goals to complete through the following steps. It was during this stage of the development where the actual contact with the users was ideal in the way that no assumptions were needed and every decision could be made with little margin of error. Thus the design process was focused in the way the information was to be displayed and finally how the site would look at the end. Even though this is a secure path to follow it is not error free, subjectiveness as a vital part of the human nature could make the design team make choices that were not necessarily those of the users. For this reason, user testing and constant thought of their needs became vital to further narrow the possibilities of not completing the established goals. ...Make it a lifestyle� (4). The end of this sentence best describes the process of creating a web site and how to ensure quality in every product made.
