Basic Overview
The list is split into 4 roughly equal sections, (I) Accessibility, (II) Identity, (III) Navigation, and (IV) Content. I’ll describe and rationalize all of the sections and line items below.

Section I. Accessibility
This section contains not only traditional accessibility issues, but anything that might keep a visitor from being able to access the information on a website. If no one can load your site, or the type is too small to read, all of the usability in the world won’t matter.

Wishing you and your family a very Happy New Year 2011

Usability is a quality attribute that assesses how easy user interfaces are to use. The word “usability” also refers to methods for improving ease-of-use during the design process.

Usability is defined by five quality components:

* Learnability: How easy is it for users to accomplish basic tasks the first time they encounter the design?
* Efficiency: Once users have learned the design, how quickly can they perform tasks?
* Memorability: When users return to the design after a period of not using it, how easily can they reestablish proficiency?
