Miro is a great tool, but a fool with a tool is still a fool...

I use it to collect ideas, to summarize thoughts. Regardless wheter I am doing brainstorming or workshops, together with others or totally alone.
Miro is a great and creative tool that doesn't block me and my thoughts but rather enables free thinking. Yes, it can be more structured than that, but my preference is to use it whithout almost any limitations and guard rails.

It has helped us a lot to collaborate in our organisation. And also when collaborating with customers, both near and far. We even developed a four day training durign the poandemic which we have been given many times during and after that. We still have our master data in Miro even though we almost never give that training digitally anymore. The agenda and all the exercise are still collected in the board. When we modify the content that often happens i sessions using Miro.
