One Major Problem with the MBO Process Is That

One major problem with the MBO process is that

A) it does not motivate employees most of the time.
B) it must start at the top of the organization and work its way down in order to work, which can be a long process.
C) it is not a healthy way to improve communication because it forces the manager and employee together.
D) when it doesn't work well in one company, other companies who haven't tried it will think it is not the optimal way to set goals and will not give it a try.
E) it leaves too many decisions up to the employees, thus causing the managers to risk losing control within the organization.
