By the end of the development phase, all code should be written and all components should have been unit and system tested. The focus of this phase shifts from getting the system built to getting the system delivered to the end users. However, the transition from finished code to finished product can be a long and fraught journey.
You have to be very careful during the final deployment phase. As the pace picks up, and the need to fix bugs becomes more urgent, there is a tendency to forget formal procedures and to just start making fixes. There is no better way to destroy Visual Basic code than to perform haphazard fixes. Of course, there are many other issues in the deployment phase, as we shall now see.
