    INVEST in good stories
    § Independent – loosely coupled with one another
    § Negotiable – Stories are what and why , not how ( 99% ).
    § Valuable – for the customer!
    § Estimatable – Effort/Cost of design, build, and test.
    § Small (sized appropriately)
    § Testable – pass or fail
