I have about ten years of professional engineering work experience. I'm working full time on a long term project with a huge client who has delegated the vast majority of my project management to an engineering intern (currently enrolled in a masters program, and working part time).
I'm familiar with "managing up" to project managers who are senior to me, and who have seen projects start, stall, flourish, flounder, succeed and fail. However, in this circumstance, the project manager has maybe had a few classes with projects -- hardly a valuable point of reference.
The intern's superior is not readily available, and from them I can usually get email responses only a few times a week. How can I effectively manage expectations of the intern who is managing my project?
