Innovation tip: divergence and convergence
Quick tip: when generating ideas it is important to remember this is the divergent phase. At some point in the future you will need to converge to smaller numbers of ideas. In fact, you will most likely go through several waves of diverge and converge in the course of ideation on a challenge. Each wave kills off some ideas and generates new ones. But the end goal is to have a set of ideas that address the specified challenge and that can be executed on.
The picture shows tools like brain writing, build concepts/synthesis sheets, and build creating ideas in a divergent phase and tools like dots, idea build sheet and idea revision narrowing sets of ideas to smaller numbers for presentation.
