Edit a crowded mind map.

Give the centre a specific job

A map called “Marketing” can spread in any direction. “How will we launch the new course?” gives it a boundary. Write the purpose before adding branches, and use it to decide what belongs. A question works well because every branch has to answer it.

Group by meaning

Check that every main branch describes the same kind of thing: stages, questions or themes. Mixing a date, a department and a goal at the same level makes the structure harder to follow. Move supporting details beneath their parent idea. If you have more than seven main branches, two of them probably belong together.

Write labels you can say aloud

Replace copied sentences with short, concrete labels. Keep enough context for someone returning later: “Risks” may need “Delivery risks”. If a branch needs a paragraph, split the idea into smaller parts or place the explanation in a note.

Use colour to carry a distinction

Give colour a consistent role, such as separating main themes. Avoid making every node compete for attention. Check that the hierarchy still makes sense without colour, through labels, position and connections, because some readers will not see the colours the way you do.

Test it with one other person

Ask someone to find an answer in the map without guiding them. Notice where they pause or choose the wrong branch. Edit those labels and groupings before adding decoration. Check that they can find the answer after your edits.

One map, before and after

Compare a science revision map before and after these five edits.

The facts did not change. The centre became a question, the branches became one kind of thing each, and every label got short enough to say in one breath.
