The 7 ways technique is a brainstorming tool that is used to encourage a team to stretch their creativity by them come up with 7 different ideas to accomplish a given function [1]. Often, 7 is number that is hard to reach which forces the team to think of creative and innovative solutions, and forces the team to think out of the box. 7 ways originates as part of 3P (Production Preparation Process )[4], which is an integral element of the Lean design process. 3P was developed to spike innovation, by embracing multi-disciplinary communication.[3] The technique is applicable to close to all disciplines.
