Many project teams make the mistake of trying to the analysis and design for all the system usage scenar ios before and coding begins. This if often referred to as big design up front or BDUF. The problem with BDUF is that in any product design process there is a chance you will get it wrong. Without meaningful testing and feedback, your ultimate design is likely to be very flawed. One myth about UML and OOA/D is that you need a complete design in order to write code. You dont. You just need enough of the design to get you started. So, designing and implementing software one usage scenario at a time, so that users can provide feedback on the end product, is a smart way of fleshing out a better design.
