Agile Atlas (see the About Page)
If you are new to Agile, and related methodologies like Scrum, here is an online “Atlas” or Dictionary about all those topics. Below is an extract from the About section explaining, in summary, the site’s purpose.
The long-range purpose of this site is to provide an “encyclopedia” of information about Agile and related methods. Although the site is presently supported only by the Scrum Alliance, it is not intended to be a Scrum-only site in any way.
You’ll also find valuable articles (@ http://agileatlas.org/articles) related to Agile and Scrum, like this one:
Scrum – a Bird’s-Eye View: A quick overview of Scrum – Agile Project Management
Enjoy It!
