This paper presents a study that examines how well-known methods for idea generation can be advantageously combined. It investigates Method 6-3-5, a group technique for six developers who successively refine three initial ideas under tight time constraints (within five minutes per round). In the conducted experiments, this commonly used brainwriting technique was complemented with a set of design heuristics that should help the participants to abstract the problem and should guide them to potential solutions.
The study (with N = 88 participants in total) compares first and third year B.Eng. students in a Mechanical Engineering programme with young professionals holding more than one year working experience. For evaluating the solutions that the participants generated, metrics were employed that measured the variety and the quantity of the ideas. The paper also analyses if more experience permits engineers to overcome the ‘fixation’ to an initial design.
