Correct Answer: B
Answer and Explanations:
Answer A: Incorrect. Real time (e.g. hours or days) is sometimes used in estimating tasks required to complete a user story. However, it is not used as a measure or indication of the team's performance.
Answer B: Correct. Velocity is perhaps the most common metric and is used to determine the team's performance over time. It is often used to compare actual performance to estimated performance.
Answer C: Incorrect. The number of escaped defects is a metric that indicates the team's performance as it pertains to the quality of work completed rather than performance over time.
Answer D: Incorrect. Cost performance index (CPI) is a measure of the cost efficiency of budgeted resources expressed as the ratio of earned value to actual cost. CPI does not provide information about performance over time.
