A project is plagued by changes to the project charter. Who has the primary responsibility to decide if these changes are necessary? A. Project manager B. Project team C. Sponsor D. Stakeholders 在这里,如果primary理解为首先的话,答案是否应该是A, 因为只有pm 先确定了变更是必须的,然后再提交sponsor做最后决定。 但如果理解为首要,主要的话,答案则应该是C. 要碰上这种一词多义的情况怎么办?
