Sequential Workflow

Use named steps for sequential execution with clear tracking.

This example demonstrates Workflows using named Step objects for better tracking and organization. This pattern provides clear step identification and enhanced logging while maintaining simple sequential execution.

Pattern: Sequential Named Steps

When to use: Linear processes where you want clear step identification, better logging, and future platform support. Ideal when you have distinct phases that benefit from naming.
