PMI Agile Certification Practitioner(PMI ACP) Exam Practice Test 1

The best answer here is that throughput has increased because one team member’s productivity has increased, which could be a cause of the other answers in this question.

The other responses are incorrect: testing could still go well with velocity being affected; development could still be efficient and productivity not increase; iterations can be accurately estimated, but productivity meets the estimate.
