UW Library – Web Usability Testing
CNAPG ProjectAmos Lakos & Anne Fullerton

Usability – What is it?
Users can use the product quickly & easily – to accomplish their tasks
Focus on users – understanding what they want & need to accomplish
Users (not designer) - determine when the product is easy to use

Web Usability – why test?(Jacob Nielsen)
To improve design – not document existing weaknesses
Average site has 11 usability catastrophes
On average – users complete 42% of test tasks
Most users rate sites subjectively – 4.9/7 – rate high

Usability Tests - methodology
Identify user population profileFind representative usersHeuristic EvaluationUsability (User) Testing
Prototype groups of 5-6 testeesFocus GroupsUser feedback – web, phone, etc.Usage Log Analysis

UW Web Usability – Why?
If users can’t find what they search for – they will go somewhere else!!!
Customer decides everything – competition is a mouse-click away
Have to make web site useful to our students & faculty – so they use it well - reduce stress & frustration - save time
Create brand loyalty – stay with UW site!!!

Project Objectives
1. Usability evaluation of current UW Library gateway
2. Redesign (& evaluate redesigns) using a series of user centred design techniques
3. Functional prototype 4. Use 8 UCD methods5. CNAPG member as a client6. Professor & TAs as project managers
& project coordinators

Phase 1 – Evaluation of the Current Gateway
Current page analysis Cognitive Design Walkthrough Heuristic Evaluation Hierarchical Task Analysis
Competitive analysis of other library gateways
Proposals for changes to gateway & preliminary sketches

Phase 2 – Evaluate Low-fidelity (non-functional) Prototypes
Card Sorting Discount Usability
Heuristics Cognitive Design Walkthrough
Prototypes on 8.5 x 11 paper
UW Library - CNAPG - WebUsability - 2001

Phase 3: Evaluate Medium Fidelity (functional) Prototypes
Key Stroke Level AnalysisLab Based User Testing
Timed Trials Subjective Evaluation
Presentation of final prototypes to class & CNAPG

Common Student Findings
Words & phrases for links not intuitiveDavis graphic distracting; hides text
versionNavigation bar missed; buttons not
obviousMouse-over & mouse-types
inconsistentDirect search of TRELLIS expected on
top page

Design Recommendations
Revise heading & subheading language (card sorting)
Majority of space for headings & subheadings
Visually connect headings & subheadings
Simplify navigation bar – consistency; add site index

Design Recommendations – cont’d
Clear UW logo (top left)TRELLIS quick search (top left)Text version explicit (top right)Colours & fonts to facilitate
reading & feedback

Next Steps
1. Language revisions – card sorting – grad students; faculty
2. Rapid prototyping – 1/week planned
3. New design – mid August
