Overview

The basic elements of BPMN processes are tasks; these are atomic units of work composed to create a meaningful result. Whenever a token reaches a task, the token stops and Zeebe creates a job and notifies a registered worker to perform work. When that handler signals completion, the token continues on the outgoing sequence flow.

Choosing the granularity of a task is up to the person modeling the process. For example, the activity of processing an order can be modeled as a single Process Order task, or as three individual tasks Collect Money, Fetch Items, Ship Parcel. If you use Zeebe to orchestrate microservices, one task can represent one microservice invocation.

Currently supported elements:

• Service tasks
• User tasks
• Receive tasks
• Business rule tasks
• Script tasks
• Send tasks
• Manual tasks
• Undefined tasks
