Scenario or use case

By regulatorily requirements or internal processes in enterprises a human approval can be needed to continue the automated process within a MLOps pipeline or process.

While AML pipelines do not yet provide a manual approval feature the project teams developed a strategy on how to shift the approval workflow towards AzDO pipelines and implemented it in the field.

Acceptance criteria

• [ ] One sample containing a human approval flow for demonstration
• [ ] Best Practice documentation around splitting the work done in AzDO and AML pipelines and where and how to inject the human approval in AzDO pipelines

Stretch Goal

• [ ] Sample for alternative approach via LogicApp or DurableFunctions (just an idea)
