Note: This document is an initial draft

the Education and Outreach Working Group (EOWG), and
will be offered to other W3C groups and the public for review.
This appendix to "Customizing a Business Case and Implementation Plan for
Web Accessibility" presents analyses of the cost/benefit factors involved in
implementing accessibility into Web presences.
Many of the factors that must be considered are listed with examples of how they might be considered from a direct expense view, an investment view, or as assets/liabilities.
Once a strategic decision is made to scope the level of effort, the
deployment will need to be translated into operational requirements with
costs applied. The costs will include training, design, quality assurance or
test processes. The impact on
current projects will also need to be assessed.
Considerations for cost and benefit:
- Accessibility Assessment
Accessibility evaluation of existing web sites, mainly done by external
consultants. [See sample assessment].
Consider management briefing, general awareness, in-depth technical training,
other. [See training suggestions].
- Subject matter expert time
External consultants time to support accessibility implementation.
- Materials, equipment, tools and assistive technologies
Need to purchase new Web authoring software [see guidelines at: ...],
and any assistive technologies for purpose of Web site evaluation and
testing [see information on assistive technologies at:... ]
- Developer time
Time needed for development of a new accessible design and retrofitting
of existing site.
- Quality assurance and testing
Internal ressources needed for accessibility testing all through the developmentt.
Travel costs for external consultants or external training of internal
Provision for other costs or unexpected overspending.
or effects on development (could be + or -):
- Accessibility Architecture (Modeling? Framework? Guidelines?)
- Site Updates
- Process for managing inaccessible legacy content
- Development of content checking process or tools
- Reduced life cycle development, operational, and maintenance costs
- Increase portability to new devices and technologies
- Potentials for economies of scale
- Trained corps of developers
or effects on site functioning (could be + or -):
- Number of pages: dynamic vs. static
- Changed Transfer rate costs
- Changed Speed of Transaction
- Variations in user agent support
- Impacts or effects on organisational place and image:
- Market share
Accessible Web site represents often new market opportunities or product
- Organisational Image improvements
An accessible site will enlarge audience and improve organisational image.
- Increased usability
Accessible desing will increase usability for all users.
- Content that is better indexed and easier to search/mine/find
Using of alt text and other acessibility features can improve search engine
- New method of providing services will lower cost of providing services
Savings in hardcopy/multimode document delivery will reduce costs of alternative
format production and distribution
