Example: if a process execution varies on a need to have basis, then please select the last highest known occurrence.

A process consists of a sequence of tasks. A process step can be seen as a process task.

In this case we understand decision making as complex when not clearly defined in a process e.g. when deciding on a business strategy. On the other side in daily operations we have clearly defined rules and execution. A clearly defined business rule in a process would for example be an if -> then relation e.g. If a list contains a task -> then execute the task.
