Abstract

Functional use-case generation may include determining whether a requirements context is available. In response to a determination that the requirements context is available, the requirements context may be determined as a task context and as a rule context for a requirements sentence of a requirements document. The task context and the rule context may be used to select a functional model from a plurality of functional models. A functional use-case that includes an entity that is to perform a task based on a rule may be generated. Further, in response to a determination that the requirements context is not available, a functional model may be selected from the plurality of functional models based on process context, where the functional model includes a process related to the process context, and the functional model that includes the process related to the process context may be used to generate the functional use-case.
