Workflow Software Challenges “Orders are confirmed in 48 hours and shipped within 30 days” “Most suppliers confirm our orders but some forget and we need to followup” “What is the status of this order and what is the next step?” Long Running and Stateful Workflows run for up to 30 days and must maintain state throughout Flexible Control Flow Flexibility for people to override or skip steps in the workflow Transparency Rendering runtime state within a visualization of the workflow control flow Real World Behavior Software Challenges

What is a workflow? A set of activities that coordinate people and / or software... EscalateToManager Example activities…. CheckInventory Like a flowchart…. …organized into some form of workflow. Or a state diagram….

Work flow types Rules-driven Activities Step2 Step1 Rule1 Rule2 Data Rules + data state drive processing order Data-driven Simple Conditions, complex Policies Constrained Activity Group State Machine Workflow State2 State1 Event Event External events drive processing order Reactive, event-driven Skip/re-work, exception handling Graph metaphor Sequential Workflow Step1 Step2 Sequential structure prescribes processing order Prescriptive, formal Automation scenarios Flowchart metaphor

What are Activities? An activity is a step in a workflow – Has properties and events that are programmable within your workflow code – Has methods (e.g. Execute) that are only invoked by the workflow runtime Think of Forms & Controls – Activity == Controls – Workflows == Forms Two broad categories of activities – Basic – steps that “do work” – Composite – manage a set of child activities

Base Activity Library Core activities provided by WF Designed for – Modeling control flow – Modeling communications Examples – IfElse, Delay, While, State, etc. – InvokeWebService, CallExternalMethod, etc. Built using the same component APIs that are exposed to developers
