Channels of Communication (Cambridge International A-Level Business)
How communication works within a business
Formal communication
-
Formal communication is the planned way a business shares information
- It is written down or recorded, so there is proof of what was communicated
-
Formal communication happens differently depending on the type of communication network
-
A communication network refers to the patterns or structures through which information flows within an organisation — in other words, who communicates with whom and how
Communication networks
1. Chain communication

Messages pass up or down the hierarchy
-
The message travels step-by-step up or down the hierarchy, following the chain of command
-
Chain communication suits tall, rule-bound organisations, such as the armed forces
- There is clear authority and accountability
- It is easy to trace who said what
-
However, it is slow, as passing the message through each layer adds time
- Details can be distorted as they pass along
- Lower levels may feel left out of decisions
2. Wheel communication

The message comes from the centre of the business
-
One central leader receives information from, and sends instructions to, every other member
-
This approach is suitable when rapid decisions are needed, such as in emergencies
- The leader has the full picture, so messages stay consistent
-
However, the message sender can suffer from information overload, as there is over-dependence on one person
- As there is little sharing between outer members, important ideas may be missed
3. Circle communication

The message is passed around the group
-
People of equal rank speak or pass the message in turn around the group
-
This approach builds team spirit and trust
- Everyone is heard , so it is good for brainstorming and problem-solving
-
However, it may be slow to reach a decision and there is no single leader to break deadlocks
- The message may have to travel a long way to reach the right person
Benefits of formal communication
| Benefit | Explanation | Example |
|---|---|---|
| Clear instructions | - Formal documents state the exact steps, deadlines and who is responsible - Staff do not have to guess or ask several people, so tasks are done the same way on every shift and in every location | - A production manager gives operators a checklist to follow before the machines run - Errors are reduced and product quality remains stable |
| A record is kept | - Saving messages as emails, minutes or forms creates proof of what was decided and who agreed - Managers can trace problems and settle arguments because the date and wording are stored | - A customer claims a delivery was late; the logistics team shows the despatch note email to prove the goods left on time |
| Fairness | - Formal channels like the intranet, noticeboards or newsletters send the same information to all employees at once - Overtime offers, training places or job vacancies are open to everyone, not just close friends of the boss | - A shop manager posts the weekly rota on the staff portal instead of handing it to favourite supervisors, so each worker can plan ahead |
| Legal protection | - Laws often require firms to keep contracts, policies and safety records; these documents act as legal evidence if audited or taken to court - They show the company followed proper rules and gave clear warnings | - After an accident on-site, a business can show the worker’s signed safety training record to prove correct training was given, reducing possible fines |
One- and two-way communication
-
One-way communication is where information moves from sender to receiver only
- The listener or reader does not reply
-
It is typically used for announcements and important instructions, e.g., fire alarms, where speed or clarity matters more than feedback
- It delivers a single, consistent message to many people quickly, with no debate to slow it down
- However, the receiver cannot ask questions, so misunderstandings can occur
-
Two-way communication is where a message is sent and then replied to
- This creates a feedback loop between sender and receiver
-
It is typically used for team meetings,customer-service chats and appraisal interviews, and situations where understanding and agreement are vital
- Feedback confirms the message has been understood and lets both sides share ideas, which can improve decisions and morale
- However, it takes more time and, if poorly managed, may lead to arguments or information overload
Vertical and horizontal communication
-
Vertical communication involves information moving up and down the hierarchy, between managers and the levels above or below them
-
It is typically used to communicate targets from directors to supervisors (downward) or progress reports from the shop floor to management (upward)
- It keeps the **chain of command clear **and ensures decisions and feedback reach the right level
- However, it can be** slow**, and messages may get distorted or filtered as they pass through several layers
-
Horizontal communication is where messages are shared between people on the same organisational level, often across departments
- E.g. the marketing manager may communicate with the finance manager about a promotional campaign budget
-
It can speed up problem-solving and teamwork by letting peers share information directly
-
However, if not copied upward, senior managers may be unaware of agreements, causing confusion later
