Q1. A scaled Scrum environment has five teams using XP practices. Each team estimates story points differently: Team 1 averages 5 points per story, Team 2 averages 8, Team 3 averages 3, Team 4 averages 5, and Team 5 averages 8. The Release Train Engineer wants to normalize velocity across teams to forecast a release. Which approach best supports this goal?

• ○Convert all teams' story points to a common baseline by comparing historical velocity and adjusting estimates accordingly.
• ○Use each team's raw velocity without adjustment since story points are relative within teams.
• ○Average all teams' story points and assign this average to all teams for future sprints.
• ○Ignore story points and use hours spent per story to calculate velocity uniformly.
