Key Idea: At HL, Topic 2.6 is about choosing the most effective communication method for the situation and explaining how communication affects coordination, motivation, speed of decisions and change management. Strong answers identify barriers and propose realistic fixes.
Core structure (memorise)
- Communication — transferring information from sender to receiver
- Verbal — spoken communication
- Written — documents, emails, reports, messages
- Visual — charts, diagrams, graphs, images
- Digital — online communication tools
- Formal communication — official channels and records
- Informal communication — unofficial channels or the grapevine
📨 Communication methods: **Verbal —** quick and allows immediate feedback. **Written —** creates a record and can be checked later. **Visual —** helps simplify data or trends. **Digital —** fast and flexible across distance.
🔄 Communication direction: **Downward —** managers to employees. **Upward —** employees to managers. **Horizontal —** between people at same level. **External —** between business and outsiders.
🏛️ Formal communication: **Formal communication —** reliable, official, consistent. Useful for policy, legal issues and important decisions. Creates evidence and accountability.
💬 Informal communication: **Informal communication —** fast and flexible. Useful for relationships and quick updates. Risk of rumour, distortion and lack of record.
High-yield facts examiners expect
- Barriers include language, jargon, cultural differences, noise, poor technology, long chains of command and information overload
- The wrong method can cause misunderstanding even if the message itself is correct
- Long chains of command increase risk of distortion
- Feedback is essential — communication is only effective if understood
- Communication problems often link to poor motivation, slow decisions and conflict
✅ Good communication: Clear language improves understanding. Right channel improves speed and effectiveness. Feedback helps check understanding. Better communication can improve morale and teamwork.
⚠️ Common problems: Too much information can overwhelm staff. Poor technology can delay or distort messages. Cultural differences can change meaning. Informal messages can spread rumour and uncertainty.
What HL examiners want to see
- HL answers should identify the most suitable method, not just any method
- Always explain why the chosen channel fits the urgency, sensitivity and audience
- A written method may be clearer, but slower; a verbal method may be faster, but leave no record
- Remote and international communication often needs special attention to time zones, language and trust
- For evaluation, discuss both efficiency and reliability
At HL, communication questions are often really judgment questions. Examiners want to know which method is best for that situation and why.
If the case involves change, conflict or remote teams, explain how communication affects motivation and implementation — not just information flow.
Example: A strong answer: Written communication may be suitable for this policy change because it gives all employees the same message and creates a permanent record. However, managers may still need follow-up meetings so staff can ask questions and reduce uncertainty.
Important: Common triggers: explain one communication barrier, compare formal and informal communication, recommend the best communication method, analyse communication problems in remote teams, or explain how communication affects motivation and performance.
- Identify whether the question is about method, direction, barrier or effectiveness
- Use the exact communication term
- Explain how it works
- Apply it to the audience and situation in the case
- Show effect on clarity, speed, coordination or morale
- For bigger questions, compare alternatives before concluding
