Concept Fan
The Concept Fan is a structured creativity technique developed by Edward de Bono that helps escape mental fixation when direct approaches to a problem have stalled. By stepping back to increasingly abstract levels of purpose — from a specific approach, to the goal, to the broader purpose, to the wider context — the Concept Fan expands the solution space and reveals alternative approaches invisible from the original problem framing. It's particularly powerful for problems where "thinking harder" in the existing direction has produced diminishing returns.
Lateral Thinking
Lateral Thinking is a deliberate creative thinking approach developed by Edward de Bono that moves sideways across a problem rather than deepening a single line of reasoning. Where vertical thinking digs deeper in one direction, lateral thinking questions the frame itself, jumps to alternative starting points, and uses deliberate techniques — random stimulation, provocation, alternative perspectives — to escape established patterns and reach solutions that logical extension of the current approach cannot find.
Lateral Thinking
Lateral thinking, coined by Edward de Bono in 1967, is the deliberate use of non-sequential, indirect approaches to problem-solving — moving sideways through problem space to find solutions that vertical (logical, sequential) thinking cannot reach. It includes techniques for disrupting habitual thinking patterns, generating unexpected options, and finding novel angles of attack on problems that have resisted direct solutions.
Provocation Technique (Po)
The Provocation Technique, introduced by Edward de Bono using the notation "Po," is a lateral thinking method that deliberately makes an absurd or impossible statement about a problem domain, then uses that statement as a stepping stone to generate creative solutions. Unlike conventional logic, which moves from valid premise to valid conclusion, Po creates a "provocation" — a statement that is intentionally unreasonable — specifically to force thinking out of established patterns. The absurdity of the provocation is its strength, not a weakness.
Random Stimulation
Random Stimulation is a deliberate creative thinking technique from Edward de Bono's lateral thinking toolkit that uses randomly selected words, images, or objects to break out of established thought patterns and generate novel associations with a problem. By forcing the mind to create connections between an unrelated stimulus and the challenge at hand, it activates lateral pathways that logic and systematic analysis cannot reach. Used in product design, advertising, and strategic planning to generate genuinely unexpected solutions.
Six Thinking Hats
Six Thinking Hats is a parallel thinking framework developed by Edward de Bono that separates six distinct modes of thought — facts, emotions, caution, optimism, creativity, and process — and assigns each a coloured hat. By having all participants adopt the same thinking mode simultaneously, teams eliminate debate-style conflict and explore problems more completely. Used by IBM, NASA, and Merck to improve decision quality and meeting efficiency.
