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.
📨 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.
✅ 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.
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.
