So you got your team together, you’re ready to rock and roll. Now the question comes, what do you do? What’s the most important part of your to-do list?  That is where the Product Backlog comes into play.   The Product Backlog is a prioritized list of project requirements with estimated times of completion.  Estimates can be done in days or hours but the more specific they are, the better it is for estimation purposes.  The higher an item is on the backlog, the more important it is.  This list is never static.  It is always being added to, changed, etc as the conditions of the business or project change.  Your backlog is created by your product owner, and then as your backlog develops you can then develop what your iterations will look like.  In easyspeak, this is your list of what you have to do, and the list you and your team have to work off of when deciding what you’re going to do and when.
