Persistence is important with unresponsive team members or even sometimes with the PM themselves. In a capstone project I participated in, with the our advisor acting as PM, we found it difficult to contact them for input outside of our weekly progress meetings due to their other obligations. To help with this issue our group was diligent in making sure any major design questions were brought up during meetings so that we could address any issues that were delaying our work on the project. The small window of communication that we were afforded in this instance actually helped us be more efficient in planning and designing among ourselves since we had to get in as much communication and input during our weekly meetings for the project to keep moving.
