Candidates for Use Cases
Ingredients
Process
Consider which situations the user could face when he uses the system. All these situations are potential candidates for a use case. Do not assess the candidates now. The gross list with all possible and less possible candidates are useful and are assessed when writing the use cases.
The customer can, with great success, be involved in this process, since it is in fact the customer's use of the system we are trying to describe. Consult the customer with the list and compile all the comments relevant for the candidates. It might be helpful later on in the development process.
Why
In order to be open-minded and not assess any possible use case candidates before the actual analysis and description of the use cases in which they participate, the developer should produce a candidate list.
By preparing the list of all possible use case candidates without assessment of the individual candidate, the developer ends up with a list that probably contains at least all possible candidates.
The assessment later on in the analysis will eliminate the candidates not suitable for the system-to-be.
