A developer who configures a Human task in a workflow nominates the users who can work on the task data. When you log in to the Analyst tool, the Start workspace lists the task instances that the workflow assigns to you. You can work on a task as a task performer or as a business administrator.
As a task performer, you can update records in the task and the status indicators in the task. As a business administrator, you can perform the same operations as a task performer. You can also reassign tasks from one user to another and move tasks to the next stage in the workflow.
A workflow can assign you different roles on different tasks. You might be a task performer and a business administrator for different tasks in a single workflow.
