Azure DevOps Delivery Plans is an extension for Azure DevOps Services and Azure DevOps Server that provides a visualization tool for managing and tracking the progress of work items and user stories across multiple teams and sprints. It’s particularly useful for organizations that are using the Scaled Agile Framework (SAFe) or other agile methodologies that involve multiple teams working on interrelated features and projects. Here are the key features and concepts of Azure DevOps Delivery Plans:

1. Cross-Team Visibility: Delivery Plans allows you to see work items from multiple teams in a single view, providing a high-level overview of what each team is working on and how their work aligns with overall project timelines.

2. Sprint and Iteration Tracking: You can view sprint and iteration schedules for each team, making it easier to understand when work items are planned for completion.

3. Drag-and-Drop Planning: Delivery Plans provides a drag-and-drop interface that allows you to schedule and reschedule work items across teams and iterations. This helps in adjusting plans in response to changing priorities or delays.

4. Dependency Management: You can define dependencies between work items, which is crucial when multiple teams are working on interrelated features. This ensures that work items are scheduled in the correct order.

5. Customizable Views: Delivery Plans allows you to create customized views to filter and display specific work items, teams, or iterations. This flexibility helps in focusing on the most relevant information.

6. Rollup Dates: The tool provides rollup dates that automatically calculate when a feature or epic is expected to be completed based on the completion of its child work items. This helps in tracking the progress of larger initiatives.

7. Integration with Azure Boards: Delivery Plans integrates seamlessly with Azure Boards, allowing you to link work items and epics to your delivery plans for tracking.

8. Permissions and Security: You can control who has access to view and edit delivery plans to ensure that sensitive project information is protected.

9. Queries and Filters: You can use queries and filters to define the scope of work items displayed in your delivery plans, making it easy to focus on specific aspects of your project.

10. Export and Sharing: You can export delivery plans to share them with stakeholders who may not have direct access to Azure DevOps.

11. Historical Data: Delivery Plans also maintain historical data, allowing you to review past iterations and releases for insights and retrospectives.

Azure DevOps Delivery Plans is a valuable tool for organizations that need to coordinate and visualize work across multiple teams and sprints. It helps in aligning teams, managing dependencies, and tracking progress at a higher level than individual team boards. It’s especially useful for organizations practicing agile at scale, where coordination and visibility become critical for successful delivery.
