extension the use case it extends to make optional interactions explicit or to handle exceptional cases, therefore allowing the description of the basic use case to remain simple A use case that makes optional interactions explicit or handles exceptional cases a high risk because for some reason their implementation is problematic. all the steps from the beginning of the use case to the end, including the handling of the unusual situation

generalization^3 superclasses in a class diagram to represent several similar use cases a high risk because for some reason their implementation is problematic. generalization, generalization^2

inclusion to allow you to express a part of a use case so you can capture commonality between several different use cases other use cases A use case that captures commonality among a set of other use cases a performing of a lower-level task with a lower-level goal

specialization subclasses in a class diagram to provide details of a particular use case in a group of use cases that are described in a generalization The inverse of generalization a high risk because for some reason their implementation is problematic.
