An agile team completes a deliverable that is to be certified by another expert team...

In an Agile context, the servant leader’s role is to support the team and help them perform their tasks in a self-organized way12. When a deliverable that needs to be certified by another team is not taken for many months, it creates an impediment to the team’s progress. The servant leader should review the process and work to remove this impediment12. This could involve facilitating communication between the two teams, adjusting the process to prevent such delays in the future, or finding alternative solutions that allow the team to continue their work effectively12. References: 12
