This project looked at whether an effective usability makeover of an enterprise analytics interface was possible in under two months through the use of low-cost methods, with an eye towards identifying best practices that could be distilled from the results.
Introduction
Objective
1. Performed cognitive walkthroughs
• Task-based method that identified “low hanging fruit” without need for user studies• Used hypothetical but realistic stand-ins known as personas in place of users• Walked through tasks on 3 competitor’s “campus profile” sites to generate ideas
Process
2. Conducted user studies
3. Sketched paper mock-ups
4. Created prototypes
Results
Best Practices IdentifiedStrategies for user studies involving executive-level users
• Start off with an easy task to build the user’s confidence and help them relax• Continually stress that this is not a “test”• Make overly complex tasks “time-permitting”
Rapid Redesign of an Enterprise Analytics Interface
The usability of simple non-interactive websites have been studied extensively, but less attention has been paid to enterprise analytics interfaces. These systems are powerful and data rich, but they frequently suffer from an overstuffed user interface. The field of User Experience Design (UXD) offers low-cost methods, both in terms of money and time, to identify and resolve user interface issues in these systems.
BackgroundThe specific enterprise analytics system studied was the Campus Profile at the University of Illinois. The Campus Profile provides interactive 10-year snapshots going all the way back to 1989 that contain over 700 quantitative indicators across more than 300 departments summarized at 4 different administrative levels.
• Conducted dry run study with “pilot” user to solidify task wording and check timing• Performed studies with target audiences: 2 with dean’s assistants, 1 with department head• Identified issues through task analysis and prioritized with simple table (see above)
• Created sketches that try to move beyond the current interface rather than “fix” it• Ideas guided by user studies and competitor site cognitive walkthroughs• Paper was used rather than computer to prevent technology from stifling innovation
• Created multiple prototypes by modifying screenshots of original interface with Paint.NET• Primary focus of prototypes was implementing fixes identified in user studies• Secondary focus of prototypes was incorporating ideas sketched in paper mock-ups

Final Prototype
Interface changes that go beyond “fixes”1. Replaced horizontal navigation bars with tabbed navigation2. Created login functionality to default to home unit data and allow report saving3. Created footer to provide visible contact information and “frame” main content
Elements added that infuse appeal and improve ease-of-use1. Added dropdown menus with built-in search to minimize scrolling (see below)2. Added instant graph functionality to save user from having to use Excel (see below)3. Enlarged Excel and Print buttons and moved them closer to the data table4. Changed navigation bars and table header colors to match colors in header
Wording/labeling issues addressed1. Added word “Items” to qualify Standard, Expanded, and Strategic navigation tabs2. Added word “Reporting” to qualify meaning of Custom navigation tab3. Added word “Profile” to qualify meaning of Change Year4. Removed abbreviations in item descriptions wherever possible5. Simplified data table header by removing dash and additional year from display
Through the use of low-cost high-impact methods, we showed how significant gains in usability can be achieved in a very short period of time, even for a complex Enterprise Analytics interface.
Conclusion
• Users ignore abbreviations and are drawn instead to spelled out words• If abbreviations must be used, use them sparingly and consistently
• Users do not read text in pop-up windows• Use modeless feedback instead – “ask for forgiveness, not permission”
• Users ignore generic “Help” buttons• Use context-sensitive help and FAQs instead; also provide Glossary
• Users don’t understand format of numbers just by looking at them• Clearly label numbers: percentages with %, thousands with “k”, millions with “M”
• Users have difficulty with complex keyboard interactions• Stick to mouse-based interaction wherever possible due to Mac/PC keyboard
differences and also due to minimal keyboard support in many mobile devices
Note: These can be applied to other types of users as well
