I work in a hierarchical organization as an operations officer for my boss. We've got three subordinate organizations each with their own operations staff. My boss is the supervisor over the three subordinate organizational leads. The problem lies in the staff to staff coordination. I have no control or authority over the subordinate organization operations staff, but I need information from them they my boss requires.
The subordinate staffs often miss the informal deadlines we set for reports and information making my staff scramble at the last minute to put information together to give to my boss. I can't give them formal tasks as they they work for those subordinate organization leads. I have to set up some kind of informal system, but don't know how to go about it. Any suggestions?
