1. UW Library - CNAPG - WebUsability - 20011 UW Library – Web Usability Testing CNAPG Project Amos Lakos & Anne Fullerton Davis Library July 10 2001

2. UW Library - CNAPG - WebUsability - 20012 Usability – What is it? zUsers can use the product quickly & easily – to accomplish their tasks zFocus on users – understanding what they want & need to accomplish zUsers (not designer) - determine when the product is easy to use

3. UW Library - CNAPG - WebUsability - 20013 Web Usability – why test? (Jacob Nielsen) zTo improve design – not document existing weaknesses zAverage site has 11 usability catastrophes zOn average – users complete 42% of test tasks zMost users rate sites subjectively – 4.9/7 – rate high

4. UW Library - CNAPG - WebUsability - 20014 Usability Tests - methodology zIdentify user population profile zFind representative users zHeuristic Evaluation zUsability (User) Testing yPrototype groups of 5-6 testees zFocus Groups zUser feedback – web, phone, etc. zUsage Log Analysis

5. UW Library - CNAPG - WebUsability - 20015 UW Web Usability – Why? zIf users can’t find what they search for y– they will go somewhere else!!! zCustomer decides everything y– competition is a mouse-click away zHave to make web site useful to our students & faculty y– so they use it well y- reduce stress & frustration y- save time zCreate brand loyalty y– stay with UW site!!!

6. UW Library - CNAPG - WebUsability - 20016 Web Usability – UW Library Goals zMake the UW Library Gateway the main window to information to our students & faculty zMake the UW Library Web site useful to our customers zUse User Centred Design – to build the UW Library web site zCreate Brand Loyalty (UW Library)

7. UW Library - CNAPG - WebUsability - 20017 UW Web Usability – what are we doing? zSystems Design Students Project zPrototype Creation zUsability Testing – 5-6 individuals yAnalysis of results yFocus groups yCreation of new prototype zRepeat test cycle

8. UW Library - CNAPG - WebUsability - 20018 UW Gateway Usability Study - background z Terms of Reference z Professor Carolyn MacGregor – cognitive ergonomics research z Systems Design 348 – User Centred Design (UCD) y CECS project – winter 1999

9. UW Library - CNAPG - WebUsability - 20019 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 methods 5.CNAPG member as a client 6.Professor & TAs as project managers & project coordinators

10. UW Library - CNAPG - WebUsability - 200110 Phase 1 – Evaluation of the Current Gateway z Current page analysis y Cognitive Design Walkthrough y Heuristic Evaluation y Hierarchical Task Analysis z Competitive analysis of other library gateways z Proposals for changes to gateway & preliminary sketches

11. UW Library - CNAPG - WebUsability - 200111 Phase 2 – Evaluate Low-fidelity (non-functional) Prototypes z Card Sorting z Discount Usability y Heuristics y Cognitive Design Walkthrough Prototypes on 8.5 x 11 paper

12. UW Library - CNAPG - WebUsability - 200112 Phase 3: Evaluate Medium Fidelity (functional) Prototypes z Key Stroke Level Analysis z Lab Based User Testing y Timed Trials y Subjective Evaluation Presentation of final prototypes to class & CNAPG

13. UW Library - CNAPG - WebUsability - 200113 Common Student Findings zWords & phrases for links not intuitive zDavis graphic distracting; hides text version zNavigation bar missed; buttons not obvious zMouse-over & mouse-types inconsistent zDirect search of TRELLIS expected on top page

14. UW Library - CNAPG - WebUsability - 200114 Design Recommendations zRevise heading & subheading language (card sorting) zMajority of space for headings & subheadings zVisually connect headings & subheadings zSimplify navigation bar – consistency; add site index

15. UW Library - CNAPG - WebUsability - 200115 Design Recommendations – cont’d zClear UW logo (top left) zTRELLIS quick search (top left) zText version explicit (top right) zColours & fonts to facilitate reading & feedback

24. UW Library - CNAPG - WebUsability - 200124 Next Steps 1.Language revisions – card sorting – grad students; faculty 2.Rapid prototyping – 1/week planned 3.New design – mid August
