Exercise 3-7: The Unfinished Solution
This is such a common scenario that I had to include it as one of the exercises. The real problem here is that you do not really know what you are starting with, and the customer has already gone through explaining what he wants and does not want to go through the whole thing again. Stories: Validate existing code Allow user to enter message Allow user to add tags to message Send message to each contact in list Customize e-mail message for each contact based on tags in profile and e-mail message Tasks for Story 1: Validate Existing Code |
