Colour and symbol codes
It’s particularly helpful when making notes on meetings and lectures to have decided on a set of symbols and colours that you can use in your Mind Maps. They have the following advantages:
You don’t need to write so much and so you save time.
You can replace frequently used concepts or themes with symbols, for example, ‘priority’, ‘email’, ‘phone call’, and ‘target’. They make it easier for you to recognise and reprocess key information in graphic form when you return to the Mind Map concerned.
Combined use of colours and symbols can be especially helpful, allowing you to present several levels of information in a single Mind Map in a very compact way – something that wouldn’t be possible in normal note-taking. For example, you can devise colour codes for particular departments or groups whose views you can then connect with them by thematic branches in the appropriate colours.
