In Scrum and other flavors of Agile, the task board represents the team’s plan for the sprint. Where I work, we have a rolling whiteboard for each team. They use one side for their task board, and one side for the release backlog and other artifacts. The board is an amazing information radiator. It contains the team’s stories, broken down into tasks. It has their written Definition of Done. It has their Sprint Burndown chart, showing the task hours remaining on each day of the sprint. It has a place to note unavoidable distractions, so that the team can make them transparent and management can detect patterns and potentially make changes to better insulate the team.
