Rule Pattern 34: Alternatives

Problem Describing Alternative Actions

Business domain experts recognize the value of describing a business process that completely describes a typical sequence of activities. Alternative actions or extensions to this main typical course of action are often described separately so that the essence of the process description remain uncluttered with details that only become necessary when greater depth is needed to understand finer points of the process.


Alternative actions and extensions may be defined in terms of conditions and variant action sequences. Adaptive use cases are specifically modeled to address these needs. An explanation of how use cases may be parameterized and specific examples are provided in the adaptive use case component of the DEAT process..
