"The Six Thinking Hats is a system designed by Edward de Bono, a Maltese physician, psychologist and author, that is widely taught in business schools as a tool for group discussions and individual creative thinking and it is, in my opinion, a great resource for innovative leaders.

"The Six Thinking Hats technique helps individuals and groups broaden their thinking by considering problems and ideas from a variety of perspectives, and is based on the old saying, “put your thinking hat on.” It involves the user visualising six different hats, each a different colour to depict a specific focus or way of thinking that needs to be considered. In practice, the technique involves an individual or group figuratively “wearing” each hat in turn, fully exploring the mode of thinking it represents and then switching to the next hat."
