Types of human task
There are four types of human tasks that you can define.
- To-do task
- This is where a service component (such as a business process) assigns a task to a human as something for that person to do.A to-do task can be implemented either stand-alone or inline.
- To see an example of a to-do task that you can build and run yourself, go to http://publib.boulder.ibm.com/bpcsamp/index.html, and click.Note: You will need a connection to the internet to view this example.
- Invocation task
- This is where a human can "assign" a task to a service component. In such a case, a human is invoking an automated service such as a business process.An invocation task can be implemented either stand-alone or inline. When it is inline, an invocation task allows humans to invoke the operations that a business process exposes through activities such as receive, pick or event handlers. Through this, a user can start a process and define authorization for its inbound activities.

- Collaboration task
- This is where a human assigns a task to another human.A collaboration task is stand-alone, in that there is no interaction between it and any other component. It is self-contained and implements a stand-alone human interaction without any reference or interface to another service.

- Administration task
- This type of task grants a human administrative powers such as the ability to suspend, terminate, restart, force-retry, or force-complete a business process. Administration tasks can be set up on either an invoke activity, or the process as a whole.This type of task is only available within a business process (inline task).
