Can provider gap 4, the communication gap, be closed prior to closing any of the other three provider gaps? why or why not?

Gap 4, which deals with lowering customer expectations, can be closed at any time. While the first three gaps are concerned with raising company performance to meet expectations, gap 4 aims to lower customer expectations to meet perceptions. The two approaches to closing the customer gap operate on different principles and therefore can occur independently. Incidentally, closing gap 4 can be more economical than closing the other gaps.
