As part of my job is to offer free Agile material in order to help you to understand the Agile concepts and practices.
First of all, I would like to share many Agile videos related to the most known framework in Agile that is Scrum. In Vimeo you will find many of them but I think that to put them inside my blog would be useful for everyone interested in Scrum.
Secondly, my humble recommendation is to start using physical board but as usual as soon as companies work with distribute team they need to implement a virtual board because of that I posted a brief summary about different Agile Tools
Last but not least, I want to share my Agile ebooks where you will find with many interesting Agile topics.
