• A workflow is a set of activities that are organized into a process that coordinates people and/or software.

• The Activity is the unit of execution, encapsulation and reuse within the workflow framework.

• Out of the box you can create Sequential Workflows, State Machine Workflows, Flow Chart Workflow.

Why Workflows?

Think about the process used when you purchase something online.

WF can be used in a variety of scenarios:

• Document review processes.

• Automated system processes.

• Help desk ticket management systems.

• Business processes tracking, such as HR compliance systems.

• Page or application flow.

Why Workflows?

Workflows can• Be long running AND

stateful.• Increase your developer

productivity as what they are assembling looks exactly like the process being modeled.

• Provide transparency into a process.

What is a workflow?

Key Concepts

• Visual Designer: Graphical and code-based construction

• Workflows are a set of Activities• Workflows run within a Host

Process: any application or server• Developers can build their own Custom Activity Libraries

Components• Base Activity Library: Out-of-box

activities and base for custom activities• Runtime Engine: Workflow execution and state management

• Runtime Services: Hosting flexibility and communication
