<p>Hi, i´m looking for a method to validate use cases (during design phase). Right now we conduct an workshop with SME´s (subject matter experts), developers and usability experts (not more than 5 people total). We try to create a bird's-eye perspective on the entire system and then brainstorm on the dependencies between new and already implemented use cases. In this workshop we discuss and validate new and undiscovered use cases and try to get a clearly defined role models of system users.</p> <p>How do you evaluate / validate use cases ?</p>

hi janel, the method we use is for an existing system and the SMEs are real end-user. i wrote some more info about &quot;our method&quot; in reply to nathanael&#180;s comment.

The method we use is some kind of human activity modelling combined with interviews and not exactly a use case validation.I think that we limit ourselves with this method, as we try to integrate new features into existing components. i tend to integrate users in use case development process too (use case goals based on requirements engineering, usability testing results etc..). then evaluate the use cases with an walkthrough (cognitive or pluralistic) or feature inspection technique with end-users.

hi nathanael, by dependencies i mean that we analyse the functions of our current system (&quot;what do we have&quot;). afterwards we analyse our new use cases (&quot;what do we want&quot;). by doing this we (might) see dependencies between our current implemented function and our new goals (derived from the use case goals). Together with end-user (SME&#180;s, as the system is quite complex), usability engineers and developers (all together not more then 6 people) we discuss our new use cases (which are developed by software engineers only!) in a workshop.
