Communication

Unit 2 · Human resource management · SL and HL

Every business function depends on information reaching the right people, in time and understood. This short topic asks you to choose appropriate methods of communication for a given situation and to explain what gets in the way. In a case study, match the method to the message, the audience and the urgency.

🎯What you need to be able to do

  • Evaluate formal and informal methods of communication for an organization in a given situation.
  • Explain barriers to communication.

📚The business management

The communication process

A sender creates a message, which passes through a medium or channel to a receiver; feedback returns from receiver to sender to confirm understanding. Barriers listed: jargon and language, too much information, noise and distance, the wrong channel, long chains of command, poor listening, cultural differences, distrust and technology failures.
Communication succeeds only when the receiver understands the message as intended.

Formal and informal communication

Formal communication
through official channels set by the organization: reports, memos, official emails, meetings, notices, appraisal forms, the intranet. Flows along the chain of command (vertical) or between departments (horizontal). Reliable, recorded and authoritative; can be slow and impersonal.
Informal communication
through unofficial channels: conversations, chat groups, social events, the “grapevine”. Fast, builds relationships and can reveal staff feelings; but can spread rumours and inaccurate information, and is not controlled.

Methods and when to use them:

  • Face-to-face (one-to-one, team meetings): sensitive or complex messages, redundancies, feedback; allows questions and body language. Time-consuming; no written record unless minuted.
  • Written (letters, reports, policies, email): detailed information, legal records, instructions to many people. Can be misread, overloaded, ignored.
  • Digital and instant (messaging apps such as WhatsApp groups, video calls, intranets, collaboration tools): fast, reaches remote teams, cheap. Blurred work–life boundaries, information overload, security risks.
  • Visual (charts, dashboards, infographics, noticeboards): data and safety instructions easy to grasp quickly.

Barriers to communication

  • Language and jargon: technical terms or a second language the receiver does not share.
  • Information overload: too many messages, so important ones are missed.
  • Long chains of command: messages are delayed and distorted as they pass through many levels.
  • Inappropriate medium: bad news by email; complex data read aloud.
  • Physical distance and noise: remote teams, time zones, a noisy factory floor.
  • Cultural differences: directness, formality and non-verbal signals vary across cultures.
  • Attitudes and trust: receivers who distrust management may ignore or reinterpret messages; poor listening.
  • Technology failures and lack of access (some staff without devices).

Overcoming barriers: choose the right channel for the message; use plain language; encourage feedback; flatten structures; train managers; translate key messages; combine methods (a meeting followed by written confirmation).

✏️Worked example

A resort must tell its 250 staff that a wing will close for six months for renovation, with 40 jobs moved to other roles and some shifts reduced. Recommend how it should communicate the decision.

The message is sensitive (jobs and income), affects everyone differently, and will spread quickly through the grapevine. Recommendation: first brief supervisors face-to-face so they can answer questions; then hold a staff meeting (in Bahasa Indonesia and English where needed) led by the general manager, explaining the reasons and plans; follow with one-to-one meetings for the 40 staff affected; confirm details in writing (letters and a notice) so everyone has an accurate record; provide a contact for questions. Doing this on the same day prevents rumours on messaging groups filling the gap.

Check it. Match method to message (sensitive, complex, urgent), audience (size, location, language) and need for a record.
Recommending one method for everything. Most real situations need a combination; explain why each method is used.

📝Practise

Work through these on paper, then reveal the answer.

1. [2 marks] Distinguish between formal and informal communication.
Formal communication follows official channels set by the organization (reports, official meetings); informal communication takes place through unofficial channels (conversations, the grapevine, social media chats).
2. [2 marks] Define the term information overload.
A situation where a person receives more information than they can process, so that important messages are missed or decisions become slower and worse.
3. [4 marks] Explain two barriers to communication in a multinational company.
(1) Language and cultural differences: messages in a second language, or different norms of directness, lead to misunderstanding. (2) Distance and time zones: teams cannot meet in person and have few overlapping working hours, so responses are slow and body language is lost.
4. [4 marks] Explain one advantage and one disadvantage of using a messaging app group for team communication.
Advantage: instant, cheap and reaches everyone on their phones, even when working at different sites. Disadvantage: important messages are buried among chat, not everyone reads them, and staff may feel they must respond outside working hours; it also creates privacy and security risks.
5. [4 marks] Explain how the grapevine can both help and harm an organization.
Help: it spreads information quickly, builds relationships and lets managers sense staff mood. Harm: it spreads rumours and inaccurate information, especially during change, causing anxiety and resistance if official communication is slow.
6. [10 marks] Discuss how a company with a tall structure could improve communication.

Problems: long chain of command causes delay and distortion; top management far from customers and staff. Options: delayering (flatter structure, faster communication but wider spans and possible overload); intranet and collaboration tools (fast, but overload); regular all-staff meetings and open-door policies; empowering teams to communicate horizontally; training managers; feedback surveys.

Judgment: technology helps but does not fix cultural problems; combining modest delayering with clear channels and a culture of feedback is likely most effective, depending on cost and the firm’s need for control.
