Communication strategies, both externally and internally, are one of the most important measures of organizational effectiveness. Organization effectiveness is determined by the individual behavior of employees. In that respect, communication barriers can have a significant effect on individual behavior. The way the employees behave stems from employee motivation. Employee motivation is directly affected by the workplace.

A hot and smelling workplace will have a negative effect on employee morale and concentration. Therefore physical barriers such as unfavorable working conditions will affect individual behavior.Communication barriers may also arise from the way in which the organizational communication structure is designed. The structure may be such that the vision and the mission of the company are not clearly communicated. The harmful effects of inadequate communication are most apparent when it comes to a competitive marketplace.

Intense competition means that the organization has to change its strategies from time to time in order to stay competitive. However no matter how efficient and effective these strategies are, they will be of little use unless they have been communicated to the employees in a way that the employees can understand.Employees must be able to understand what the vision, mission, goals and objectives of the organization are and how they can contribute to furthering these measures of organizational effectiveness.

This is an issue that will strongly affect the level of employee motivation. In a situation where the employees are left wondering how their activities fit into a larger picture, they will not be motivated to improve the level of their efficiency and effectiveness.This will necessarily have a negative effect on individual behavior with the associated repercussions on individual productivity.

Inasmuch as poor communication resulting from communication barriers discourages employees from giving of their best, it is critical for the management to make sure that communication barriers such as physical barriers, system design barriers, attitudinal barriers, etc. are removed from the scheme of things in terms of their ability to affect individual behavior.
