In the traditional waterfall model of software development, the first phase of requirements analysis is also the most important one. This is the phase which involves gathering information about the customer's needs and defining, in the clearest possible terms, the problem that the product is expected to solve.

This analysis includes understanding the customer's business context and constraints, the functions the product must perform, the performance levels it must adhere to, and the external systems it must be compatible with. Techniques used to obtain this understanding include customer interviews, use cases, and "shopping lists" of software features. The results of the analysis are typically captured in a formal requirements specification, which serves as input to the next step.

Well, at least that's the way it's supposed to work theoretically. In reality, there are a number of problems with this theoretical model, and these can cause delays and knock-on errors in the rest of the process. This article discusses some of the more common problems that project managers experience during this phase, and suggests possible solutions.
