Abstract: A method of developing software capable of performing a task, the task comprising at least one task step required to perform the task. The task step has a resultant effect. The method comprises recording a use case comprising one or more scenarios, that comprise one of more further steps; recording the scenario or one of the scenarios as a main success scenarios such that the resultant effect of the main success scenario is the same as the resultant effect of the task step. Use cases which have been stripped of context-specific information may be re-used. Such information may be included in a reference to the re-used use case.

Abstract: A method of developing software capable of performing a task is disclosed. The task comprises at least one task step required to perform the task. The task step has a resultant effect. The method comprises: recording a use case comprising one or more scenarios, the or each scenario comprising one or more further steps; recording said scenario or one of said scenarios as a main success scenario such that the resultant effect of said main success scenario is the same as the resultant effect of said task step. Also disclose is the re-use of use cases which have been stripped of context-specific information. Such information may be included in a reference to the re-used use case.
