Every now and then there are Impediments in the Sprint that block the progress of work. These impediments and the work needed to remove them can be made visible in the Sprint Backlog. To do this, a sign is used to mark blocked work (e. g. a stop sign magnet). The work to remove the impediment is included and treated like any other work in the Sprint Backlog. If necessary, you can mark the affected work items in red to make the connection to the obstacle visible. This integration of impediments in the Sprint Backlog has the advantage that all work is in one place.
