A "virtual scrum board" (or something similar) could enable a layer of collaboration across the OpenIDEO community that is hard to manage today. The lead or team driving a concept could define a task that needs to get done to move the concept forward (e.g. testing a prototype with a group of end beneficiaries, figuring out the technology that would best fit a use scenario, building a financial model, etc). A challenge-wide or community-wide scrum board (or Trello board) would provide one place to find all the work requests from across concepts. A community member could easily see those tasks and offer to complete one. Then the lead or team driving a concept could track which tasks had been picked up, work directly with the collaborators, and integrate the results back into the overall project.
When you post an idea today you can list the help you would like to get from the community. However it's hard for the community to easily see all the requests (you need to go one by one through the ideas), see when new tasks are added, or see if a task is completed or already underway. This new scrum board functionality would make task-level collaboration a lot easier. It could allow the community to tap the diverse skills available in the community. And it could give people who want to build a specific skill (or portfolio around a skill) a way to focus their participation.
A scrum board would be a great addition to the Refinement phase, allowing the whole community to keep working together on the short-listed ideas. It would also allow the community to stay involved and help in the Impact phase.
