A task which is executed by a person (usually), on a single occasion.
Description
The activity is atomic in nature, and can not be broken down in a natural way. Of course, it can be broken down into several steps (activity steps), in the same way that atoms can be split, but since nothing changes in terms of performer, occasion and usually not place, we choose not to describe activity steps in models. Instead, a detailed description in text form that is linked to the activity is recommended.
Example
- Verification of received goods / services against invoice
- Pick up a good
- Pay at the register
