Creation and refinement of the product backlog can be achived in different ways.
Roman Pichler, in is post originally written in Jul, 16 2012 - http://www.romanpichler.com/blog/agile-product-innovation/the-product-canvas , has proposed a really interesting approach: use canvas to create and share product vision and product backlog creation and refinement.
I used this approach for a while with cool results.
These slides are a step-by-step introduction of the tool.
Please send me feedbacks to correct and improve it!
