Prestudy/Conceptualization Phase
The prestudy/conceptualization is the initial activity needed to establish the core requirements that satisfy a well-defined user need and to identify the risks involved in the project by establishing a proof of concept for the project. It is not in the scope of the prestudy/conceptualization to completely analyze all aspects of the requirements, it should rather establish a vision of the underlying idea. It should also validate the assumptions on user needs and implementation technology. One way to do this can be to build an early prototype that illustrates the goals of the project. The prototype may also be an aid in the identification of risks, e.g. related to technical aspects or to the functionality of the system.
In many cases the prestudy/conceptualization can be viewed as a project by itself, following essentially the same steps and phases as any other project, with the exception that the time scale is shorter and that the result is not a finished system. The tangible results from the prestudy/conceptualization should be:
