Summary statement

Measuring and monitoring accessibility has been a very important

requirement to support Web Engineering processes. Accessibility

metrics are important contributions to enable to perform quantitative analysis

regarding accessibility.

Key concepts

Providing accessible applications is a key issue to enable a more inclusive

Web and to broaden access to everyone, regardless of disabilities.

Key arguments and relationships

Metrics are very important to help understanding, controlling, and improving

products and processes in software development. In terms of accessibility, metrics can be especially useful in two situations: companies may improve the

accessibility of final products and companies beginning the software

development can introduce accessibility issues in the development process.

Key findings and contributions

When choosing one or more metrics to be used in a Web Engineering process,

it is important to perform a careful comparison between the metrics.

Ideas, observations and critiques

High correlative coefficient between different metrics should not mislead from concentrating current project – there might be situations where on metric doesn’t make any sense in

meaning of current project.

General ideas

The most effective approach for better choosing a good metric is to perform user tests and comparing the results with different metrics obtained from

inspection evaluations.

Conclusion:

which metric is BEST for each project depends on project.
