A workflow includes at least one stage. A stage supports defining users as task owners and assigning to each task owner the permissions required to perform tasks. Using multiple stages supports grouping sets of tasks and activities in a workflow. You must define all stages in a campaign workflow before executing the campaign. Executing a campaign locks the campaign workflow, preventing modifications.

Use stages to organize a workflow. For example, a typical workflow has two stages:

Different users may have defined tasks in each stage. Organizing a workflow using a logical sequence of stages supports one role, such as Campaign Manager, which is responsible for completing tasks in multiple stages of a campaign.

For example, in a typical company, one group owns data collection tasks, another group owns data validation tasks, and another group owns data modeling and analysis tasks. A workflow uses stages to sequentially group tasks in a campaign. Stages support timely completion of tasks triggered by time and tasks triggered by events.
