Key Idea: At HL, Topic 2.2 is about how structure affects communication, control, speed, flexibility and decision-making. Students are expected not only to define structures, but to evaluate which structure suits the business best and why. HL students also need to understand Shamrock organizations and project-based structures.
🏢 Tall structure: **Tall structure —** many management levels. **Narrow span of control —** fewer subordinates per manager. **Long chain of command —** slower communication. **Often gives clearer supervision and tighter control**.
⚡ Flat structure: **Flat structure —** fewer management levels. **Wide span of control —** more subordinates per manager. **Short chain of command —** faster communication. **Often gives more flexibility and quicker decisions**.
🎯 Centralisation: **Centralisation —** top managers keep decision-making power. **Better for —** consistency, control, crisis situations. **Risk —** slower local response and weaker empowerment.
🔄 Decentralisation: **Decentralisation —** lower levels make more decisions. **Better for —** speed, motivation, local responsiveness. **Risk —** inconsistent decisions and weaker overall control.
✅ Possible benefits: **Flat structures** may improve speed and staff empowerment. **Delegation** may motivate staff and reduce manager overload. **Decentralisation** may help branches respond to local market conditions.
⚠️ Likely drawbacks: **Flat structures** may overload managers. **Too much delegation** may create mistakes if staff lack skill. **Decentralisation** may lead to inconsistent decisions or weak coordination.
☘️ Shamrock organization (HL only): **Shamrock organization —** workforce split into core workers, contracted specialists and flexible part-time/temporary labour. **Core workers —** permanent staff who are central to the business. **Contractual fringe —** outsourced specialists or contractors. **Flexible labour force —** part-time or temporary staff used when needed.
🗂️ Project-based structures (HL only): **Project-based structure —** teams formed around specific projects. **Useful for —** innovation, construction, consulting, tech and creative work. **Can improve flexibility and accountability for project outcomes**. **Risk —** duplication, unclear authority, conflict over resources.
At HL, do not just state that a flat structure is faster. Explain whether faster decisions are actually more valuable than close supervision for that business.
Structure questions are often really about consequences. Always explain how the structure affects communication, quality of decisions, motivation and manager workload.
A strong HL move is to use the Shamrock or project-based model as part of evaluation, not just definition. Ask whether the business needs lower costs and flexibility, or whether it needs stronger unity, consistency and long-term commitment.
Example: A strong answer: A flatter structure may suit the business because it allows faster communication and quicker decisions during growth. However, if managers already supervise too many staff, a wider span of control could reduce support and increase mistakes.
Important: Common triggers: compare tall and flat structures, explain span of control, analyse delegation, explain delayering, recommend whether decision-making should be centralised or decentralised, or evaluate Shamrock and project-based structures.
- Identify whether the question is about structure, delegation, control or communication
- Use the exact business term
- Explain how it works
- Apply it to the business in the case
- Show the effect on speed, control, motivation or coordination
- For bigger questions, weigh both sides before concluding
