  1. 1. MIPAW Model for a Progressive Implementation of Web Accessibility Authors Jean-Pierre VILLAIN (Qelios) - @villainjp Olivier NOURRY (Qelios) - @OlivierNourry Dominique BURGER (BrailleNet) Web4All – April 2012 @Qelios
  2. 2. Currently: Methods rather than Methodologies Excellence-based approach Gradual approach Conformance Requirements Means Conformance Requirements Means =Goal Maximal Controls =Indicator Relative Quality Certification Management 2012 Advantages Advantages Service to users, Guarantees Mastered, Adaptable Main Risks Main Risks Over-quality, Changes the project Users under-served, Lower priority Tends to adapt Tends to adapt the project the accessibility requirements to the accessibility requirements to the project’s capacities
  3. 3. Limits of Excellence-based Approaches Certification is effective, but it is not sufficient 100% conformance on everything, Are the efforts really better than worth the results? 100% conformance on what is useful? 2012 We must not discard certification, We must make it smarter
  4. 4. Limits of current Gradual Approaches The constraints of the project define how requirements are handled WCAG levels are Measuring conformance: not structuring What does 75% anymore conformance mean? Users needs are deprioritized 2012 We need gradual implementation phases consistent with users needs
  5. 5. The Basis of MIPAW How to choose what to start with, while addressing users’ most urgent needs? 2012
  6. 6. The very Primary Need… Access to information? 2012 Can WCAG be structured with this angle?
  7. 7. A Preliminary Survey Workgroup • 8 experts • Accessiweb checklist Goal • To study the notion of « Access to information » related to user impact 2012 Method • Classification of each criterion on 2 axes: • Does it prevent access to information for some users? (yes/no) • If not, assess user impact (strong/weak)
  8. 8. Findings of this Preliminary Survey Criteria A AA AAA Total Critical for access to information 35 3 7 45 Non-critical, with strong impact 33 10 16 88 Non-critical, with weak or null impact 14 7 8 • Access to information is a structuring notion • All 3 WCAG levels are represented in each set • A first set of criteria considered as critical for access to information, can 2012 be defined. Covers all 3 levels.
  9. 9. From Access to Information, to MIPAW Another result appeared A secondary classification, based on these indicators: presence, relevance, and strength of user impact (significant or null with regards to access to information) Access to information Group 1 Group 2 Access to Presence info: 2012 20 criteria significant Access to impact Relevance info: null 59 criteria impact 25 criteria 29 criteria
  10. 10. Inception of MIPAW The Model for a Progressive Implementation is based on this distribution Principle: to distribute the criteria on an arbitrary scale, structured by the notion of « access to information » Access to information Essential Device UX Improvement 3.Significant 1.Presence 2.Relevance 4.Null impact impact 2012 Groups descriptions: 1. Securing Access to Information 2. Guaranteeing Access to Information 3. Improving User Impact 4. Improving User Experience
  11. 11. MIPAW and WCAG Conformance Compatibility with WCAG levels and conformance 100% WCAG conformance on each level is reached when criteria are met in the 4 groups, for the considered WCAG level. Access to information Essential Device UX Improvement 3.Significant 1.Presence 2.Relevance 4.Null impact impact Level A Level A Level A Level A WCAG Conformance Essential needs Level AA Level AA Level AA 2012 Level AA Level AAA Level AAA Level AAA Level AAA In this model, the threshold « Access to information » is considered as the pivotal point to identify essential users needs.
  12. 12. Outlooks for MIPAW Some of our expectations regarding this Model for a Progressive Implementation of Web Accessibility: • To be representative of a possible gradual implementation strategy • less demanding than purely excellence-based approaches • yet with no compromises with regards to essential users needs. • Likely to provide an adequate support for project management methodologies with gradual implementation phases, while remaining focused on users needs. • Theoretical playground for couplings between WCAG, excellence-based 2012 approaches, and gradual strategies. • Can support measurement systems that include defect-tolerance
  13. 13. Current status of MIPAW • Community project led by Qelios and Braillenet • 16 partners have expressed their interest (next page) • 5 workgroups have been constituted: Technical Definitions Certification Users Measurement 2012 Methodologies • First real-size tests: end of Q2-2012 • Publication of first results: end of 2012
