Solution
In the scalar chain principle, Gang Plank is used for a faster way of communication. Suppose, D has to communicate with G, then the information has to go from C to B to A, again from E to F and then G. Now, because of the presence of a gang plank, there is faster exchange of communication from D to G and vice-versa which helps in smoother and easier communication. It ensures that management principle is flexible and can be moulded according to the need.
