Communication is the critical the part of our life. We communicate based on our encountered situation. There are two main forms, verbal and nonverbal. It often varies how we heard as said by the speaker. In the place of law an enforcement organization, both formal and informal communication channel is used as many barrier is addressed that makes the communication to be effective. For both verbal and nonverbal forms, an individual send a message through a channel and receiver receives it from other end. On the way, the massage can be de-formed in terms of meaning and there are external elements that could make it totally an opposite meaning as sent.
In my current working environment, I encounter language as the effective communication. I work for an Indian owned IT consultant base company. India is a multi-language country and there are consultant coming from all over the India. The main language is Hindi and 30 % of them understand it well. English is the 2nd language and the form of it even two sources e.g. some follow the American standard and some British. Median of them has admixture of Hindi and both of the English sources. 60% of them speaking in Telegu which is classic area based language. As a coordinator, when I started I had the hard times to get along with them as the Language was the hurdle of our effective communication. To get rid of this barrier, we introduced paper based information system thus the communications doesn’t get distorted. Example: regardless of origin, they all have to fill up a questioner that gives a perfect description of them self and wanting’s. We use the answers to communicate with all of them and thus the noise in the communication get reduced. In times, we found that by geographic location their expertise grows, like southern part they are good at Java language and eastern part they are good at .Dot net. We separated according to the expertise and engaged one management representative to that group who eventually mediator in between management and the consultants.
Self-perception is the way we perceive our self. It is based on our self-respect, concept and the value. Self-esteem is the much we value our self. Concept is how we think what people think about us. And own perception is based on past experiences. Efficiency is the confidence of own self like “I can do it no matter what.”
Environmental perception is based on how the information is received. For instance if we say to our beloved “I love you” and the same thing. If we read a script in our drama lesson: I love you" the perception will be changed. It is for the environmental changes that do the charm. Since they are grouped as per the common environments, among the group they share massages effectively.
Learned perception is the based on out personality our culture and the habit, this perception are our thoughts our ideas and the beliefs. Example is the children react on how they were taught by parents on their religion and social reactions. As the single management act as the mediator per group, the noise in the communication is reduced.
Physical perception is based on the tangible world. Our eye and ear receive something and our mind process it, for instance, how we react to our color; red is danger to romantic to us and blue is calm and water. Our reaction of color based of physical perception. Common group coming from same geographic location has the more or less same understanding as tangibility is concern. This reduces the noise big time.
In the conclusion, the communication is the way we send and receive information between two points. The complete process is sending the information from one, encoding the message, finding a way to transmit the message, receiving the message, decode the message and the finally the feedback and the noise in between. There are few barrier to effective communication. We can divide them in four categories; e.g. physical, semantic, process and psychosocial. To improve the effective communication we must develop awareness from our school level. We have to improve our listening skill as well.
