    Finally, you’re ready to estimate the whole project...

    You’ve got short, focused user stories, and you’ve played planning poker on each story. You’ve dealt with all the assumptions that you and your team were making in your estimates, and now you have a set of estimates that you all believe in. It’s time to get back to the customer with your total project estimate...

    Note

    You’ve got an estimate for each story now.

    Add an estimate to each user story for how long you think it will take to develop that functionality.

    Add up the each of the converged estimates for your user stories, and you will find the total duration for your project, if you were to develop everything the customer wants.
