  • 1. Providing better scaffolding - how BS8878 affects people designing inclusive user experiences
    Prof Jonathan Hassell
    Director, Hassell Inclusion ltd.
    Chair, BSI IST/45
    UK-UPA Call to action: Designing inclusive user experiences
    16th September 2011
  • 2. IST/45 view: what accessibility really should be…
    • all about disabled people
    • 3. aim shouldn’t be accessibility… or even usability… but a great user experience for disabled and elderly people
    • 4. whether they can get the right value out of what you create
    • 5. exactly what you aim for, for every other audience
    • 6. you don’t want to exclude 10m+ people from using your products…
    • 7. so why don’t more organisations do it?
  • How does BS8878 help?
    • presents the business-case for accessibility and digital inclusion
    • 8. gives advice for how to embed accessibility strategically within an organisation
    • 9. shows a process which identifies the key decisions which are taken in a web product’s lifecycle which impact accessibility
    • 10. recommends an informed way of making these decisions…
    • 11. and a way of documenting all of this to ensure best practice
    Organizational Web Accessibility Policy
    WebProduct Accessibility Policy
    WebProduct Accessibility Statement
  • 12. The accessibility of your web productsis in all these people’s hands…
    Project Mgrs
    Product Mgrs
    Research & Testers
  • 13. Embedding motivation
    • Need to motivate each group…
    • 14. Or just use a business case for the top level and set policy top to bottom…
    • 15. check out OneVoice business cases…
    Project Mgrs
    Product Mgrs
    Research & Testers
  • 16. Embedding responsibility
    • Work out whose responsibility accessibility should ultimately be…
    • 17. Make sure they delegate (and monitor results) well
    • 18. Make sure those delegated to are trained in their responsibilities
    Project Mgrs
    Product Mgrs
    Research & Testers
  • 19. Embedding through strategic policies
    • create an Organizational Web Accessibility Policy to strategically embed accessibility into the organization’s business as usual
    • 20. including where accessibility is embedded in:
    • 21. web procurement policy
    • 22. web technology policy
    • 23. marketing guidelines
    • 24. web production standards (e.g. compliance with WCAG, browser support, AT support)
    Project Mgrs
    Product Mgrs
  • 25. Harmonising accessibility with user-centred/inclusive design processes
    • relating web accessibility to wider human-centred and inclusive design practices
    • 26. and bringing in concepts of user-personalised approaches…
    From: ISO/FDIS 9241-210
    Human-centred design for interactive systems
  • 27. Yes,there are16steps(sorry…)
  • 28. An informed way of making good decisions
    • every decision taken could affect whether the product will include or exclude disabled and elderly people
    • 29. so every decision should be:
    • 30. recognised as a decision
    • 31. have all options and implications considered
    • 32. made based on justifiable reasoning
    • 33. noted in the Web Product’s Accessibility Policy for transparency
    • 34. at every step of the process
  • BS8878 Product process - 1st stage: doing the right research & thought before you start…
  • 35. 2. Define its target audiences
    can you predict/control who will use it?
    e.g. an Intranet
    or an extranet
    • or will be used by a range of audiences?
    • 36. is it designed for a particular audience?
  • 4. Note any platform or technology preferences& restrictions
    • for example:
    • 37. lack of ability to download & install plug-ins or browser updates
    • 38. IT policy restrictions in offices, colleges preventing use of browser preferences, installation of assistive technologies
    • 39. strong platform preferences due to worries of cost/complexity/security
    • 40. will impact on technology choice, platform choice, reliance on ATs to mediate website experiences
    • 41. cf. rich-media technologies like Flash and ‘alternative versions’
    • 42. accessibility isn’t about luddite-ism; it is about understanding what your audience really need…
  • BS8878 Product process - 2nd stage: making strategic choices based on that research
  • 43. 7. Consider the degree of user-experience the product will aim to provide
    • degrees:
    • 44. technically accessible
    • 45. usable
    • 46. satisfying/enjoyable
    • 47. an example for online Pacman:
    • 48. Technically accessible = can control Pacman using a switch
    • 49. Usable = have a chance of winning as the ghosts adapt to the speed of interaction of my switch
    • 50. Satisfying = have the right level of challenge (not too easy or too hard)
    • 51. define the aim for each combination of user group and user goal
    • 52. BS8878 doesn’t tell you what level you should pick, just lets you know what the options are, and asks you to choose a level you feel you can justify
  • 9. Consider the delivery platforms you will support(and their accessibility implications)
    • which platforms are you going to support, and what degree of accessibility will you aim to achieve?
    • 53. useful research to have:
    • 54. are you in control of which platforms your users will use your product on?
    • 55. no, if it’s available publicly via a browser
    • 56. yes, if it’s an intranet or only available as an app
    • 57. are your users likely to have a preference on the platforms on which to use your product?
    • 58. options for degree of accessibility to aim for across different platforms?
    one accessible product for desktop, hope standards will make it work on other platforms
    as (1) but with UI tweaks (device detection) and accessibility testing on other platforms
    versions optimised for each platform, including appropriate UI and functionality subset, fully tested
  • 59. BS8878 Product process -3rd stage: production, launch and maintenance
  • 60. Quality of data
    User testing
    Remote testing
    User reviews / interviews
    Expert walkthrough
    Testing with assistive technologies
    Automated testing
    14.Assure the product’s accessibility through production
    • creating an accessibility test plan
    • 61. which testing methods will be used…
    • 62. at what points of the production process…
    • 63. sticking to the plan
    • 64. finding out whether you are achieving your target degree of UX
    • 65. when the ideal isn’t possible…
  • 66. 15. Communicate accessibility decisions at launch
    • working out which compromises you can launch with… and which you can’t…
    • 67. achieving the minimal viable product and managing accessibility risk
    • 68. communicating all those decisions & compromises to your audiences…
    • 69. in an easily found accessibility statement on your website
    • 70. which your audiences can understand…
    Confusing help text: A number of sites accessed by participants provided help pages which were so technical that they were practically useless. Mention of plugins and cookies resulted in complete confusion by the users and apprehension about whether they were able to follow the instructions given.
  • 71. Summary: in a team/organisation that follows BS8878
    • you’ll be expected to take accessibility seriously by product managers
    • 72. you’ll be in a team where each member knows what accessibility expects from them
    • 73. they’ll ask you to follow a user-centred design process(like I guess you want anyway)
    • 74. they’ll ask you for/give you real-world user-research to help good decision making
    • 75. you’ll be empowered to make decisions re accessibility, as long as you can justify them, and write them down
    • 76. you’ll have the freedom to create product variations where users’ needs diverge
    • 77. you’ll have a place to find best practice help for accessible design beyond the web
    • 78. you’ll be asked to test products for accessibility, alongside usability, to the level the budget will allow (and they’ll be aware of the limited benefits of cheap options)
    • 79. you’ll be freed from the impossibility of doing everything you could possibly do for v1.0, as long as you tell your audience why and when they’ll get what they need
  • Innovation
    Strategy & research
  • 80. Standards for the next generation of accessibility - BS8878
