A Scrum team is visualizing the blockers that arise when they work on their activities...

The most important principle in Scrum is reducing work in process (WIP). The lower the number of items, the lower the risk of items getting blocked. Based on the team’s capacity, they should set the lowest WIP limits possible.

The team should look at all the blockers, determine the reason behind them, group them, and determine if there is a pattern. They should then determine what and how they can make relevant changes.

The team should discuss the issue with their scrum master because it is their responsibility to remove impediments, such as blockers, in cooperation with other teams.

Blockers are a result of bottlenecks. The team should ask for more resources to prevent bottlenecks from arising and reduce the risk of long lead times.
