We provide models of good practice that you can be confident in because of the Standards we routinely apply.

One of these standards concerns a design’s usability.

Literate users should be able to find at least 90% of what they look for (l), and effectively use 90% of what they find (f).

To arrive at a minimum overall usability standard we multiply 90%(l) x 90%(f). Giving us a composite minimum score of 81%.

We use that 81% as a logo for MODEL CRI PROJECTS.
