Here's some of the best practices for impediments in Scrum I would like to share.

- Provide the team with access to the data it needs: One common impediment in Scrum is the lack of access to the data needed to complete a task or deliver a product increment.

- Improve data quality and reliability: Poor quality or unreliable data can be a major impediment for a Scrum team.

- Build the necessary infrastructure: Another common impediment in Scrum is the lack of the necessary infrastructure to support the team's work.

- Automate data-related tasks: Data engineering can help solve impediments related to manual, time-consuming data tasks by automating these processes.

- Provide data-related training and support: Data engineering can also help solve impediments related to the team's lack of data skills or knowledge by providing training and support to help the team effectively use data in their work.

Overall, at the end of the day it needs to deliver value and meet its commitments.
