It is a fact that for one particular event, people have different perceptions.  Perception differs among individuals, mostly because of different culture, beliefs, and unique personal history. It is also a fact that perception will lead to emotions. For example, fear if a danger is perceived or confidence if a great adventure is perceived.  

When an organisation is going through a change, managing perceptions is a strategy that will reduce resistance, accelerate acceptation and facilitate adopting the change as designed.

It will help ensure the vision of the change is the same among the management team, enabling them to manage perceptions among their employees right from the start. By managing perceptions, the management team will reduce rumors, undesired behaviors and resistance.

A positive perception of the change will lead to the positive emotions needed to go through the transition and achieve success.
