Basis of Decision-Making and Planning

Communication is essential for decision-making and planning. It enables the management to secure information without which it may be possible to take any decision. The quality of managerial decisions depends upon the quality of communication. Further, the decisions and plans of the management need to be communicated to the subordinates.

Without effective communication, it may not be possible to issue instructions and orders. Effective communication helps in the proper implementation of plans and policies of the management.

Smooth and Efficient Working

Communication makes possible the smooth and efficient working of an enterprise. It is only through communication that the management changes and regulates the actions of the subordinates in the desired direction.

Motivation to Work

Employees are motivated to work if their needs are satisfied. Communication helps managers know the needs of their employees so that they can adopt suitable motivators and inspire them to develop a positive attitude towards the work environment.

Job Satisfaction

Principles of Communication

The 7 Cs provide a checklist for making sure that your meetings, emails, conference calls, reports, and presentations are well constructed and clear – so your audience gets your message.

These are the principles of communication and according to the 7 Cs, communication needs to be

  1. Clarity
  2. Completeness
  3. Coherence
  4. Conciseness
  5. Credibility
  6. Correctness
  7. Continuity
Principles of Communication
Principles of Communication


The writing should be correctly planned and expressed in a logical way, and the writer should make sure that the ideas flow smoothly from beginning to end. The message must be so clear that even the dullest man in the world should readily understand it.


Completeness is an essential factor for effective communication. A message must be organized appropriately in the sense that it must include all the important ideas and their details. The contents of the message must be checked in order to verify that there is no omission of the relevant details. An incomplete message can do little to convey the information and persuade the receiver.


Coherency is equally essential for good written communication. Clear communication in simple sentences helps the reader to understand. Facts and figures must be stated plainly and in an intelligent manner. Relation and clarity are the two important aspects of coherence. Coherence means, tying together several ideas, under one main topic in any paragraph.


Conciseness is an important factor in effective communication. It means saying all that needs to be said and no more. The aimless verbiage, unnecessary details, and heavy paragraphs make our communication ridiculous and ineffective. We must omit those words and sentences from our message, which are not likely to bring about results.


Good writing is always forceful and direct and has the power and capacity to produce a reaction or desired effect. The clarity in writing brings about credibility because it ensures that others understand the message easily and quickly.


Without correctness, readers may refuse your write-up. Communication must be correct in tone and style of expression, spelling, grammar, format, contents, statistical information; stress-unstressed, etc. there should not be any inaccurate statements in the message.


As far as possible the writer should avoid jargon. Jargon is a language that is special to science, commerce, technology, trade, and profession. In writing, the jargon should not be incorporated as this could make the writing confusing and unclear. Brevity or the use of fewer words brings about continuity and grace in your writing

Process of Communication

Communication consists of the following eight components which are interrelated to the process of communication

  1. Idea
  2. Sender or Encoder
  3. Encoding
  4. Message
  5. Channel and medium
  6. Receiver or Decoder
  7. Decoding
  8. Feedback
Process of Communication
Process of Communication


Every message, whether oral or written, has its origin in an idea that germinates in the mind of the sender of the message. Every idea refers to some context. Thus the idea or information that the sender wants to convey to the receiver is the source of the message in the communication process.

Sender or Encoder

The person who initiates the communication process is referred to as the encoder. The process of communication begins with the sender who identifies the need to communicate. The sender must have a clear picture in his mind about what he wants to communicate and should accordingly select symbols, words, images, etc.

The sender must identify his audience and formulate the message in such a way that the receiver understands fully what he intends to convey and interprets it within the same context.


Encoding takes place when the sender formulates his idea into a message to be transmitted to the receiver, using a series of symbols- verbal/ or non-verbal, written or oral. The sender should encode the message keeping in mind the purpose of communication and should select words or symbols that help the receiver understand the communication correctly and achieve the expected feedback.

Encoding is the process of creating a message for transmission by an addresser to an addressee. A way that an individual puts his thought together with the way he is going to communicate. Eg: using a speech by thinking of another language and the way he is going to put it in a sentence and also if he is going to use sign language.

The sender, as well as the receiver, should attach the same meaning to the symbols or words, otherwise, communication will fail. Thus proper encoding is essential for successful communication.


A message is an idea transformed into words. It can be expressed in different ways depending upon the subject matter, purpose, audience personal style, and cultural background of the sender.

Channel and medium

An appropriate medium chosen to send the message is known as a channel. It is the vehicle that facilitates the sender to convey the message to the receiver. Channel is a system used to transmit a message, whereas medium is one of the forms/ types used under that system. For example, oral communication is a channel and telephone conversation is a medium. There are three broad channels of communication and there are several media under each.

Receiver or Decoder

The person who receives the encoded message is referred to as the receiver. The receiver may be an individual or a group of individuals. As communication is a two-way process, the receiver is as important as the sender of the message. A receiver may be a listener or a reader or a viewer of the message.

He not only receives the message but also tries to understand, interpret and perceive the total meaning of the message.


Decoding is a process by which the receiver interprets the message and translates it into meaningful information. The meaning of the message is the sum total of the meanings of the words ( symbols) together with the tone and the attitude of the sender as reflected by his choice of words and the structure of the message.


Feedback is the response given by the receiver of the message to the sender of the message. When the encoder receives feedback, he gets to know that communication has been accomplished. Feedback can be immediate, later, and can be positive or negative. It can be verbal or non-verbal.

In communication, feedback plays an important role. It ensures that the receiver has received the message and understood it just as it was intended by the sender. Feedback is the most important component of communication. Without feedback, the communication process is incomplete.

Types of Communication

These are types of Communication.

  1. Verbal Communication
  2. Non-Verbal Communication
  3. Written Communication
  4. Visual Communication
  5. Feedback Communication
  6. Public Communication
  7. Mass Communication
  8. Group Communication

Verbal Communication

Verbal communication can be done with the use of language to transfer information with help of sign language or speaking. It is considered the most common type. It is used during presentations, video conferences, meetings, one-on-one conversations as well as a phone calls. Verbal communication is important because it is an efficient way of communication.

It can be helpful to support both non-verbal and written communication. Steps include in verbal communication are the use of a strong, confident speaking voice, using the active listing, and avoiding filler words.

There are four types of communication: 1. Intrapersonal Communication, 2. Interpersonal Communication, 3. Oral Communication, 4. Public Communication

Non-Verbal Communication

Non-Verbal communication includes the use of body language, facial expression, and gestures to convey information to others. It can be used both unintentionally and intentionally, you might smile unintentionally when you are pleasing or enjoying a piece of information or idea. Non-Verbal communication is useful for understanding the thoughts and feelings of others.

Written Communication

Written communication includes acts of writing, typing, and printing symbols like numbers and letters to convey information. It is helpful; because this communication provides a record of information for future reference. Writing is generally used to share information through pamphlets, books, letters, blocks, memos, etc. Emails and chats are common forms of written communication at the workplace.

Visual Communication

This is the act of using photographs, sketches, drawings, arts, graphs, and charts to convey information. Visuals are often used as an aid during presentations to provide helpful context along with written and/or verbal communication. Because people may have different learning styles, visual communication might be considered more helpful for some to consume information and idea.

Feedback Communication

When the individuals, who are in leadership positions in educational institutions and in various forms of organizations, such as instructors, supervisors, heads, directors, employers, and so forth, put into operation various types of assessment methods to evaluate the performance of the individuals. After evaluating the performance, they provide their feedback in terms of their performance.

Public Communication

Public communication occurs when a group becomes too large for all members to contribute. One characteristic of public communication is an unequal amount of speaking.

Mass Communication

Mass Communication is the process of delivering information, ideas, and attitudes to a sizeable and diversified audience. This is done through the use of media developed for that purpose namely newspapers, magazines, radio, television, websites, and social media networks.

Group Communication

Communication by many persons in a face-to-face situation is described as group communication. Here, as the group grows in size communication tends to become more and more of a monologue reducing participation.

Elements of Communication

Let us analyze Joseph A Devito’s definition that ‘communication refers to the act by one or more persons, of sending and receiving messages distorted by noise, within a context, with some effect and with some opportunity for feedback’ to find out the essential elements of communication.

According to his definition, communication has the following elements

  • Sender or Decoder: A person who sends a message or a signal is the source of communication. Communication by definition demands that someone send signals and someone receive them.
  • Message: Message is anything that is sent and received. Generally, we think of communication messages as being verbal (oral or written). We can also communicate nonverbally.
  • channel: It is the route or vehicle along which the message is transmitted from a sender to a receiver. When you talk to a friend, the sound waves that carry your words constitute the channel. When you write something, the piece of paper becomes the channel. Newspapers, magazines, radio, television, and the internet become the channels of mass communication.
  • Receiver or Decoder A person who receives the message or signal is the receiver in a communication process.
  • Noise: Noise in communication refers to anything that distorts or interferes with the message. The screeching of a passing car, sunglasses a person wears, prejudices, bias, poor grammar etc. interfere with the effective and efficient transmission of messages from the sender to the receiver.
  • Feedback: The information that is fed back to the source is known as feedback. Feedback, in general, refers to any process by which the communicator obtains information as to whether and how his/her intended receiver has received the message.
  • Context: Communication always takes place within a context. It can either restrict or stimulate the communication process. Communication in a funeral home, a public park, a cricket stadium, and a church will be entirely different.
  • Effect: The consequences of communication are referred to as effects. Communication has always some effect on one or more persons. The effect could be on the source or on the receiver or on both of them.
