Before trying to improve communication competencies one should keep in mind the barriers to effective communication. This follows from theory that problem identification is the first step in problem resolution.
The barriers to great communication are physical, cultural, perceptual, emotional, language, gender, and interpersonal. In the situation we are considering, all these apply in varying degrees. With regards to this scenario and backdrop, the main concern here are the language, cultural, perceptual and emotional barriers.
In order to improve the group’s communication competencies it is important that each know what background the other is coming from in order to better understand their colleagues. This is important not only in terms of the top-down and bottom-up flow of communication, it is also important for a horizontal flow of communication as colleagues need to understand each other to do better team work.
