There are two popular ways to create brainstorming diagrams. The first is to begin with a main idea and then generate related topics and subtopics hierarchically. However, during a brainstorming meeting where people are contributing ideas in rapid succession, hierarchies aren't always apparent, and you need to capture ideas quickly. The second way, then, is to capture all of those ideas as they're expressed, and later to organize, revise, refine, and share the results.
Create a brainstorming diagram
In the Templates categories page, click Business > Brainstorming diagram > Create.
Alternatively, click the File tab, click New, click the Business category, and then double-click Brainstorming Diagram.
From Brainstorming Shapes, drag the Main Topic shape onto the drawing page. The main topic is the central theme of the diagram. With the shape selected, type the text you want the main idea to represent.
Select the Main Topic shape, and then, on the Brainstorming tab, in the Add Topics group, click Subtopic or Add Subtopic. A subtopic connects to and is subordinate to the Main Topic shape.
Add more topics to your brainstorming diagram
Add multiple subtopics at once
Select the topic that you want to add subordinate topics to, and then, on the Brainstorming tab, in the Add Topics group, click Multiple Subtopics.
In the dialog box, type text for each new topic, and press ENTER after each one. When you are finished adding all the topics that you want, click OK.
Add one topic at a time
Select the topic you want to add a same-level or subordinate topic to, and then, on the Brainstorming tab, in the Add Topics group, click Peer or Subtopic.
A peer topic is a topic added at the same level in the hierarchy as the selected topic.
Move a topic to a different location on the same page
Select the topic and drag it to the location you want on the drawing page.
If the topic has subordinates, they move with the topic and their connectors reposition automatically.
Move a topic and its subordinates to another page
Select the top-level topic in the section of your diagram that you want to move to another page, and then, on the Brainstorming tab, in the Arrange group, click Move Topic To New Page.
In the Move Topics dialog box, under Move to, click New page. Type the name you want for the new page, or keep the default, and then click OK.
Move a topic without its subordinates to another page
Right-click the topic you want to move to another page, and then click Copy.
Navigate to the page that you want to add the topic to, right-click the page, and then click Paste.
Move a topic to another level
In the Outline Window, drag the name of the topic that you want to be subordinate directly on top of the name of the topic you want to be superior.
All subordinate topics move with the topic, and the changes are reflected in your diagram.
Tip: If you don't see the Outline Window on the drawing page, on the Brainstorming tab, in the Manage group, select Outline Window.
