Incubation can be particularly helpful after hearing other people’s ideas. You may not think of new ideas right away, but odds are, your brain is still working on it in the background. So, if you get stuck, sleep on it. Tomorrow will likely bring fresh ideas. Another common way of getting unstuck is to look to analogous products for inspiration.
For many product teams, this means competitive research. You should draw inspiration from your competitors, but look broader than that. Many innovative ideas come from unrelated domains.
