Has anyone figured a good method for facilitating an asynchronous (not the same time/place) remote design sprint? The typical design sprint happens synchronously (same time/place), and is done in-person with different stakeholders. I am trying to figure a good way to make this happen remotely using a tool like Mural. The reason I ask about doing this asynchronously and remotely, is because many of the stakeholders are not at the same location, and our schedules are not flexible enough to block off an entire week for a design sprint.
I was thinking of creating a Mural board with an initial set of questions to be answered individually by stakeholders (session time-boxed to 2 days), and let the stakeholders come in at various points in time within those two days to contribute. This will continue for a couple weeks, with each session marking the five stages of the design sprint (Unpack, sketch, decide, prototype, test).
