Dual reporting causes confusion, complicates prioritization, diminishes focus on clear goals, and muddies the lines of supervision and accountability-- especially when the supervisors are in two different departments. When situations require dual reporting, managers need to be informed. Asking someone from another department to do a task without consulting with his or her manager is strictly prohibited (unless the request will take less than an hour or so).
