| Activities are the fundamental concept for defining processes.&nbsp; Activities define the breakdown as well as flow of |
| work.&nbsp; In other words, Activities can be nested into each other defining a breakdown structure of work or they can |
| define predecessor relationships to other Activities defining a flow presented in Activity diagrams.&nbsp; Activities |
| can also contain references to Task, Roles, and Work Products called <a class="elementLink" |
| href="./../../../base_concepts/guidances/concepts/descriptor,_5V9HEBUEEdqrUt4zetC1gg.html" |
| guid="_5V9HEBUEEdqrUt4zetC1gg">Descriptor</a>.&nbsp; Activities as well as Descriptors relate to timelines by allowing |
| their instances to define start and/or end dates.&nbsp; Further, they specify information relevant to the instantiation |
| of work in project such as if an Activity shall be performed several times and if so if they can be performed in |
| parallel (hasMultipleOccurrences attribute) or one after other (isRepeatable attribute).&nbsp; Activities and Task |
| Descriptors can also be event driven or describing ongoing work that does not have a fixed start and end time. |

| UMA defines several&nbsp;special Activities that allow expressing processes with terms many users are familiar |
| with.&nbsp; For example, Phase or Iteration are just special Activities for which specific attribute values have been |
| set with predefined values. A process such as a <a class="elementLink" |

| href="./../../../base_concepts/guidances/concepts/delivery_process,_EhgqwO8MEdmKSqa_gSYthg.html" |
| guid="_EhgqwO8MEdmKSqa_gSYthg">Delivery Process</a>&nbsp;is also nothing else than just a special Activity that |
| contains additional documentation on why and how to use the process. Hence, because Activities could be nested into |
| each other, so can processes. |
