Key concepts in Organizational structure

Key Idea: Organizational structure is about how a business is arranged. It shows who reports to whom, how decisions move, and how much control managers have. In exams, this topic is usually about comparing structures and using the right key terms.

๐Ÿข Tall structure: Many levels of management. Long chain of command. Narrow span of control. Clear authority and supervision.

โšก Flat structure: Few management levels. Short chain of command. Wide span of control. Faster communication and decisions.

โœ… Possible benefits: Tall structure = better control and support. Flat structure = quicker decisions. Delegation = motivates staff and saves manager time. Decentralisation = local managers respond faster.

โš ๏ธ Common problems: Tall structure = slow communication. Flat structure = managers supervise too many people. Too little delegation = managers overloaded. Too much decentralisation = inconsistent decisions.

Use the exact keywords examiners want: hierarchy, chain of command, span of control, delegation and delayering. These score better than vague wording.
Example: A flat structure has fewer management levels, so communication is usually faster. This can help the business make quicker decisions, but managers may have too many employees to supervise effectively.
Important: State features of a hierarchical structure, explain delegation, compare tall and flat structures, or explain how span of control affects communication and control.
  • Identify whether the question is about structure, span of control, chain of command, delegation or delayering
  • Use the exact business term correctly
  • Explain what it means in simple words
  • Apply it to the business in the question
  • Show the effect on communication, speed, control or motivation
