With Respect to Revising Sales Territories

With respect to revising sales territories:

A) Once a set of territories is carefully and accurately established,the boundaries should not be tampered with.
B) When a territory is reduced in size,the sales rep should be allowed to retain key accounts in his or her former district,especially if those customers prefer to deal with him or her.
C) Good sales reps should not be limited by territorial boundaries.
D) Overlapping territories are okay if they stimulate competition in the sales force.
E) If territorial revision has been done properly,a sales rep in a now-smaller district may end up with higher sales and earnings than before the redistricting.
