Q.1
14 MarksLanguage in professional communication should be:
- Clear and simple: short sentences and common words, so the message is understood the first time.
- Concise: no unnecessary words or repetition.
- Precise and accurate: exact facts, figures and technical terms (for example "torque of 20 N·m", not "a lot of torque").
- Formal and polite: no slang; courteous tone even in complaints.
- Objective: based on facts, not personal feelings.
- Correct: right grammar, spelling and punctuation.
- Audience-oriented: suited to the reader's level of knowledge.
Explain the flow of communication in a professional setting (e.g., upward, downward, horizontal, diagonal).
In an organisation, information flows in four directions:
- Downward communication: from superiors to subordinates, such as instructions, policies, targets and feedback. Example: a project manager assigns tasks to engineers. It must be clear to avoid confusion.
- Upward communication: from subordinates to superiors, such as reports, suggestions, requests and complaints. Example: an engineer submits a weekly progress report. It helps managers know the ground reality.
- Horizontal (lateral) communication: between people at the same level, often in different departments. Example: the design engineer discusses a drawing with the production engineer. It improves coordination and teamwork.
- Diagonal (cross-wise) communication: between people at different levels in different departments. Example: a quality supervisor talks directly to the purchase manager about a faulty supplier. It saves time, but should not bypass the chain of command too often.
In addition, the grapevine is the informal flow of information through personal contacts. It is fast, but can spread rumours.
Explain the Shannon-Weaver model of communication and evaluate its effectiveness in today’s digital age.
The Shannon-Weaver model
Claude Shannon and Warren Weaver (1949) gave a linear model of communication, first made for telephone and radio signals. It is called the "mother of all models".
Elements:
- Information source (sender): creates the message, for example a person speaking.
- Transmitter (encoder): changes the message into signals, for example a phone converting voice into electrical signals.
- Channel: the medium that carries the signal, such as a telephone line or radio waves.
- Noise: any disturbance that distorts the signal on the way, such as static on a line. Noise can be physical, technical or semantic (wrong meaning).
- Receiver (decoder): changes the signal back into a message.
- Destination: the person for whom the message is meant.
Weaver later added the idea of feedback, so the sender can know whether the message was received correctly.
Example: a manager (source) speaks into a phone (transmitter); the voice travels over the mobile network (channel); a poor signal (noise) breaks the voice; the engineer's phone (receiver) reproduces it; the engineer (destination) hears an incomplete instruction.
Effectiveness in today's digital age
Strengths:
- Still very relevant to digital systems: emails, video calls and messaging apps still encode, transmit, decode and suffer from noise (network lag, compression, typing errors).
- The idea of noise helps us plan: use clear language, check the connection, and confirm important points.
- It is simple and helps engineers design better communication systems (error correction, bandwidth).
Limitations:
- It is linear and one-way; today's communication is interactive and two-way (chats, comments, live polls), with instant feedback.
- It ignores meaning, context, culture and emotion. A message can arrive technically perfect but be misunderstood, as with sarcasm in a text message.
- It does not consider many-to-many communication on social media, where one post reaches thousands who respond and share.
- It treats the receiver as passive, while digital users actively choose, filter and reinterpret content.
So the model is a good base for the technical side of digital communication, but must be combined with interactive models (such as Schramm's) to explain human communication today.
The Shannon-Weaver model describes communication as source, transmitter, channel with noise, receiver and destination; it still explains the technical flow and noise in digital media, but its one-way, meaning-free view is too simple for today's interactive, social communication.
