What can increase the effectiveness of Backlog Refinement?

Correct Answer:C
One of the factors that can increase the effectiveness of Backlog Refinement is to schedule the event on a regular cadence. Backlog Refinement is the process of reviewing, updating, and prioritizing the backlog items to prepare them for future iterations or sprints1. By scheduling the event on a regular cadence, such as once or twice per week, the team can ensure that the backlog is always accurate, relevant, and ready for planning2. A regular cadence also helps the team to avoid cramming too much work into a single session, which can lead to lower quality and reduced collaboration3.

What is one method to establish a team's velocity?

Correct Answer:C
One method to establish a team's velocity is to compare the average story points completed throughout the previous iterations. This gives an indication of how much work the team can realistically deliver in a given time frame, based on their past performance. To calculate the team's velocity, you can use the following formula: Team velocity = total story points completed / number of iterations. You can also use various charts and tools to visualize the team's velocity and track itsprogress over time1234
