I need some help to try to solve this. I have a major project and I need information from a co-worker related to that project by certain, spaced deadlines. He fails to deliver for whatever reason (usually poor). I still want my co-workers input but I am afraid I will get nothing or what I do get will not be well thought out and I will have to live with the consequences. Any suggestions on how to motivate my coworker? (Boss is ineffective so don't say to go higher up.)
So far I have done an end run around this issue and I can do the project without my coworkers input but the result will not be as satisfactory.
