Finished!? Not quite. The implementation of all major requirements concludes the construction phase of the project and leads to the transition phase, when the product is rolled out. The release of the product, however, involves a few more steps: formal testing of all implemented features in the form of integration and system tests, tracing of requirement keys to code, and of course deployment. All these steps are addressed in the next iteration, which is described in Chapter 13.
