The daily planning work is connected with writing concepts and publishing reports. In simple cases it’s more than sufficient to write down a simple structure e.g. in a word processing software.
If the problem looks more complex it’s a good idea to use a software to structure the cognitions and to use this structure for further development. In these cases I use MindManager (from MindJet, http://www.mindjet.com/) – it’s a commercial software that can convert the MindMap directly to a word document.
