Surely, the most difficult part of controlling any organization is Human Resources. The normal individual differences between people are a natural factor to cause this difficulty. Things that are great for some are simply "unacceptable" for others and so on. Even incentives can cause havoc sometimes, when those in charge remain "surprised" and cannot understand what's going on. People are complicated and personal choices cover a vast spectrum that can be very difficult to understand by the manager implementing control measures.
