Welcome to SpiffExample Documentation

What is SpiffExample?

SpiffExample is a sample implementation of SpiffWorkflow. SpiffWorkflow is a workflow engine written in Python, based on the Workflow Patterns initiative. This document focuses on using SpiffWorkflow to create business applications from Business Process Model and Notation (BPMN) documents.

What is Business Process Model and Notation?

Business Process Model and Notation (BPMN) is a diagramming language for business process flows. BPMN links the realms of business and IT, and creates a common process language that can be shared between the two.

BPMN describes details of process behaviors efficiently in a diagram. The meaning is precise enough to describe the technical details that control process execution in an automation engine. SpiffWorkflow allows you to create code to get a BPMN up and running.

When using SpiffWorkflow, a client can manipulate the BPMN diagram and still have their product work without a need for you to edit the Python code, improving response and turnaround time.

Today, nearly every process modeling tool supports BPMN in some fashion making it a great tool to learn and use.
