Miro, a decent product that was often shoe horned into unhelpful scenarios.

The problem in my case with implementation is that we were required to post all materials to Miro. This felt like Miro was being used more as a way to surveil team progress and create arbitrary metrics of project development. It allowed management to be lazy, and rather than coming in person to see prototypes of real-world physical objects; they preferred it all be documented on Miro.

To Miro's credit, it is a large, easy-to-use system. The learning curve, while not steep, was also not incredibly user-friendly. As stated previously, many of its functions are a bit opaque at first or are not immediately obvious as to what they do. For our use, we stuck primarily to simple functions.

Miro's strength is in visuals and its ability to create collage material from static images, gifs, videos, links, and other assorted ephemera. This allows multiple people to run with a spark of an idea and expand it, creating a web of reference material that increasingly deepens the range of possibilities.
