What is the best advice you should give them, given the quick success they have had with Labyrinth?

A) Efficiency is the only key to their continued success.
B) Now it is time for them to consider only effectiveness because they clearly have efficiency under control and this is not likely to change in the future.
C) To continue their success, they should maintain a clear focus on both effectiveness and efficiency, especially while their company is experiencing such a high growth in sales.
D) They should maintain the status quo without implementing any changes to continue making quick sales.
E) As top-level managers, the best action plan for them is to begin to minimize collaboration with customers and suppliers because they have proven themselves.
