21. You monitoring the number of change requests submitted by customers to determine if the software meets the needs of the customers. When a change request is received, the customer is kept involved in the redesign process in order to reduce the number of change requests received in the future. In some cases, the number of change requests is reduced; in other cases, it is increased.

What are three explanations for this apparent discrepancy? (Choose three.)

A.
The software does not do what customers want it to do and more requests are generated.
B.
The software has increased market share to the point that it has saturated the market.
C.
The software is very good, and widely used; more requests are a natural result.
D.
The company is responsive to customers' requests and customers know their requests are taken seriously.
E.
The software is seriously flawed but customers continue to use it because its interface is very similar to other products on the market in the same price range.
