Cisco Crosswork Network Controller (CNC) Workflow Automation is a tool that simplifies and automates complex network operations and other business processes. It provides a centralized platform for creating, managing, and executing workflows, allowing for manual operator intervention during workflow execution while ensuring repeatability and fault-tolerance.

Workflows are defined using a standardized Domain Specific Language based on the Serverless Workflow specification, enabling workflow designers to express complex business processes, dependencies, and decision logic in a unified and readable format.
