Work Guidelines: Role Playing
Each member of the group is assigned a role that is of
interest to the system. Roles are users, the system itself, other systems, and
sometimes entities that are maintained by the system. The group then walks
through how the system is used. Along the way, there will be discussions about
who is responsible for what—take notes on the responsibilities of each role.
Having the system analyst play the role of the user or customer helps gain real
insights into the problem domain.
As a frame work for the role play, you may perform
scripted walkthroughs of how the system is used. If you have some use cases
outlined, you can use them as a basis for the script. The walkthrough can also
be performed at a business level, using the business use cases as a basis for
the script.
Another technique often combined with role playing is
Class Responsibility Collaboration (CRC) cards.
