SCAMPER is a structured creative thinking checklist developed by Bob Eberle that prompts designers to approach an existing product or idea from seven distinct angles: Substitute, Combine, Adapt, Modify/Magnify/Minimise, Put to other uses, Eliminate, and Reverse/Rearrange. Each prompt forces a different type of transformation on the design challenge, systematically exploring the space around an existing idea rather than searching for inspiration in an open-ended way. It is particularly powerful for improving and innovating on existing products rather than designing from scratch.
