Add New Customer Account : This user story is also a very common feature. There will be very little database work here, and the entry screen is straightforward, too. We give this story an estimate of 3.0 story points. Edit Customer Account : This user story is much like the Add New Customer Account user story. Initially, the team talks about leveraging the work from the Add New Customer Account user story, but the XP coach reminds them that it will be the order in which the user stories will be completed is the customer’s decision. The estimate should be based on doing the user story all by itself. If it turns out later that the team can leverage work already completed for, say, the Add New Customer Account feature, then the team will finish this Edit Customer Account story earlier than estimated, and they will go back to the customer and ask for more work. Also, there is a difference here, where the user as well as someone with administrative rights can execute this feature. The administrator can edit any customer’s data, but the users can edit only their own data. This will add to the complexity of the feature. So, the team talks some more and arrives at an estimate of 3.5 story points.
