Our presentation of MIPAW at Web 4 All 2012.
MIPAW is a model for a possible strategy of gradual implementation of Web accessibility. It aims at providing a basis for project management methodologies relying on implementation phases, while remaining focused on essential users needs.

    • MIPAW Model for a Progressive Implementation of Web AccessibilityAuthorsJean-Pierre VILLAIN (Qelios) - @villainjpOlivier NOURRY (Qelios) - @OlivierNourryDominique BURGER (BrailleNet) Web4All – April 2012 @Qelios
    • Currently: Methods rather than Methodologies Excellence-based approach Gradual approach Conformance Requirements Means Conformance Requirements Means =Goal Maximal Controls =Indicator Relative Quality Certification Management2012 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
    • 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
    • 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 deprioritized2012 We need gradual implementation phases consistent with users needs
    • The Basis of MIPAW How to choose what to start with, while addressing users’ most urgent needs?2012
    • The very Primary Need… Access to information?2012 Can WCAG be structured with this angle?
    • A Preliminary Survey Workgroup • 8 experts • Accessiweb checklist Goal • To study the notion of « Access to information » related to user impact2012 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)
    • 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, can2012 be defined. Covers all 3 levels.
    • 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
    • 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 impact2012 Groups descriptions: 1. Securing Access to Information 2. Guaranteeing Access to Information 3. Improving User Impact 4. Improving User Experience
    • 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 AA2012 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.
    • 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-based2012 approaches, and gradual strategies. • Can support measurement systems that include defect-tolerance
    • 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 Measurement2012 Methodologies • First real-size tests: end of Q2-2012 • Publication of first results: end of 2012
    • Partners of the MIPAW Project2011
