The steps in designing use cases are:
? Identify the users of the system
? Creating a user profile for each category of users. This includes all roles that the users may play and relevant to the system.
? Identify essential goals associated with each role. Also, identifying the significant roles.
? Creating use cases for every goal associated for a use case template. This also includes maintaining the same abstraction level for the entire use case. Higher level use case steps are considered as goals for the lower level.
? Structuring the use cases
? Reviewing and validating the users
