Ideation is both synchronous and asynchronous
Though starting as a synchronous exercise, ideation also contains asynchronous aspects. The first rough ideas are generated in a synchronous setting. The first roughs get enhanced, and new ideas surface. When the well of fresh ideas dries up, it’s time to let the results incubate. During this asynchronous incubation period, a handful of ideas are further enhanced and finally develop into projects. Or the team starts over again.
