Do you often find yourself lost in a maze of tasks within your projects? Are checklists not enough for you to keep your projects organized? With the new Microsoft Planner, you can bring order to chaos with subtasks, enabling you to manage complex plans and projects with ease. Available in premium plans in the new Planner, subtasks are the key to unlocking a more organized and efficient workflow.

What are subtasks?

Subtasks are the building blocks that support your main tasks. They allow you to break down complex deliverables into manageable pieces, ensuring that every detail is accounted for without losing sight of the big picture.

Using subtasks, you can:

  • Organize complex projects so you can easily find what you're looking for.
  • Break down large deliverables into smaller, more actionable tasks, without losing sight of the big picture.
  • Assign responsibility of subtasks for efficient collaboration.
  • Monitor progress of your high-level deliverables based on the status of subtasks.

With Copilot in Planner (preview), staying organized becomes effortless! Using the power of AI, Copilot can help you break down your complex tasks into manageable subtasks, making it even easier for you to focus on what matters most. Learn more about Copilot in the new Planner.

How to use subtasks

When you use a premium plan in Planner, creating and managing subtasks is a breeze. Just follow these steps:
 

1. Add a task below the main task you wish to expand.

 

2. Open the task menu and select the option to convert it into a subtask. You can also use Alt + Shift + Right Arrow on your keyboard as a shortcut.

 

 

3. Enjoy the flexibility to assign, set dates, prioritize, and add attachments to your subtasks, just like any other task.

How to use Copilot to create subtasks

1. Locate the task number of the task you wish to expand.

 

2. Select the Copilot button to open the chat pane.


 

3. Enter the following prompt into the prompt area, replacing [task number] with the number you located in step 1: "Add actionable subtasks for [task number]."

 

4. Select the Send icon and relax as Copilot generates your subtasks.



 

5. If you are happy with the tasks Copilot generated, you are free to continue working with your plan. If not, select the regenerate button and Copilot will try again.
