Workflow Orchestrator

Workflow --> Command Centers --> Processors

Rules

• One common Model across the workflow
• One common Delegate across the workflow
• No 3rd party library dependent calls from the workflow, All library should be wrapped using the delegate function
• Processors are usually single responsibility, consumes the input, handles and produces the output
• No logic inside the delegates and delegate all the system dependent calls
• Processor are to handle data, design UI and do control flow via command centers and workflow using Processor
• All Processors are initialized by workflow, no explicit initialization and are singleton by design
