Startup Weekend is an event to iterate on a business idea over a weekend. When we originally pitched the dev.lab project, we struggled for a week and a half because we did not have a muscle for conducting discovery. Our project manager suggested the three-day exercise after we struggled to make progress. Depending on the individuals involved, how well you framed the discovery activity, and whether your people are pioneers, settlers, or town planners. Consider it an option if you find yourself putting too much effort into work without validating the need.
