1. Web Design Process CMPT 281

2. Outline How do we know good sites from bad sites? Web design process Class design exercise

3. Good sites and bad sites

9. Web Design Process Overview Discovery – assess needs Exploration – create multiple designs Refinement – detail chosen design Production – prepare for handoff Implementation – build site Launch! Maintenance – measure & improve

10. Design Exercise

11. Design the perfect website for CMPT 281 – You are the users (and the designers) – What do students want to do at a course site? – What are the prof’s goals for the site? – What are the main tasks? – How will you organize the site and the pages? – Sketch it out! – We will discuss your designs at the end of class

12. Design Process Exploration

13. Goals of Exploration Phase Generate multiple designs – visualize solutions to discovered issues – information & navigation design – early graphic design Select one design for further development – use patterns, usability testing, & client feedback to evaluate

14. Patterns in Exploration Phase Tend to be more abstract Site genres Navigational framework Home page Content management Trust and credibility Basic ecommerce Advanced ecommerce Completing tasks Page layouts Search Page-level navigation Speed

15. Important concepts Design Representation Usability User capabilities Task analysis Rapid prototyping User evaluation (these will all be covered in more detail later!)

16. Design Design is driven by requirements – what the artifact is for – not how it is to be implemented – e.g., phone not as important as “mobile” app. A design represents the artifact – for websites these representations include: screen sketches or storyboards flow diagrams/outline showing task structure executable prototypes – representations simplify

19. Web Design Representations Storyboards

20. Web Design Representations Mock-ups

21. Usability According to the ISO: The effectiveness, efficiency, and satisfaction with which specified users achieve specified goals in particular environments This does not mean you have to create a boring design or something that is only good for novices – it all depends on your goals

22. Usability/User Experience Goals – Learnable e.g., faster each time through – Memorable from session to session – Flexible multiple ways to do tasks – Efficient perform tasks quickly – Robust minimal error rates good feedback so user can recover – Discoverable learn new features over time – Pleasing high user satisfaction – Fun Set goals early & later use to measure progress Goals often have tradeoffs, so prioritize Example goals

23. User-centred Design “Know thy User” Cognitive abilities – perception – physical manipulation – memory Organizational / job abilities Keep users involved throughout – developers working with target customers – think of the world in users terms – not technology-centered/feature driven

24. …so, how do you get to know the user?

25. Task Analysis & Contextual Inquiry Observe existing work practices Create examples & scenarios of actual use Try out new ideas before building software

26. Rapid Prototyping Build a mock-up of design so you can test Low fidelity techniques – paper sketches – cut, copy, paste Interactive prototyping tools – HTML, PowerPoint, Flash, etc. Fantasy Basketball

27. ESP Evaluation Test with real customers (participants) – w/ interactive prototype – low-fi with paper “computer” Low-cost techniques – expert evaluation – remote, online testing
