What this dot point is asking

This outcome wants you to explain how a business is organised internally, shown on an organisation chart, and to use the key terms: hierarchy, chain of command, span of control, and delegation. You should also compare tall and flat structures. The central idea is that the shape of an organisation affects how decisions and communication flow, and how staff are supervised and motivated.

The organisation chart and hierarchy

An organisation chart is a diagram showing the structure of a business: who reports to whom, the different roles, and the levels of authority. The hierarchy is the arrangement of staff into levels of authority, from the top (directors and senior managers) down to the bottom (operatives and junior staff).

The answer

Chain of command

The chain of command is the line of authority running from the top of the organisation to the bottom. Instructions pass down the chain, and staff report up it. A long chain (many levels) can slow communication; a short chain speeds it up.

Span of control

The span of control is the number of subordinates a manager is directly responsible for. A wide span means many staff report to one manager; a narrow span means few do.

  • A wide span lowers costs (fewer managers) and gives staff more freedom, but each manager may be stretched and able to give less support.
  • A narrow span allows closer supervision, but costs more and can feel controlling.

Delegation

Delegation is passing authority for a task down the chain to a subordinate, while the manager keeps overall responsibility. Delegation frees managers to focus on bigger decisions and can motivate staff by giving them responsibility, but the manager must trust the subordinate to do the task well.

Tall versus flat structures

  • A tall structure has many levels and narrow spans of control. It allows close supervision and clear promotion steps, but communication is slow (a long chain), and it is expensive with many managers.
  • A flat structure has few levels and wide spans of control. Communication is fast (a short chain), costs are lower, and staff are often more empowered, but managers supervise more people and there are fewer promotion steps.

Examples in context

Example 1. A flat structure in a small tech start-up. A start-up of 12 people may have just the founder and everyone else reporting to her, a flat structure with a wide span of control. Decisions are quick because the chain of command is short, and staff are trusted with responsibility, which motivates them. The risk is that the founder is stretched supervising so many people, illustrating the trade-off of a wide span.

Example 2. A tall structure in a large bank. A large bank may have many layers: directors, regional managers, branch managers, team leaders and clerks, with narrow spans at each level for close control of money and risk. This gives tight supervision and clear promotion ladders, but a decision or message can take a long time to travel up and down the long chain of command, showing why big, control-heavy organisations tend to be tall.

Try this

Q1. Define delegation. [2 marks]

  • Cue. Delegation is passing authority for a particular task down the chain of command to a subordinate, while the manager retains overall responsibility for the outcome.

Q2. State two features of a flat organisational structure. [2 marks]

  • Cue. Any two of: few levels in the hierarchy, wide spans of control, a short chain of command, faster communication, lower management costs, or more delegation to staff.

Q3. Explain one advantage for staff motivation of widening managers' spans of control. [4 marks]

  • Cue. A wider span means a manager supervises more staff and cannot oversee every detail, so more authority is delegated to workers. Being trusted with responsibility for their own tasks can motivate staff, making them feel valued and increasing job satisfaction, which may raise effort and productivity. So wider spans can improve motivation by pushing genuine responsibility down to the workforce, provided staff are capable of handling it.

Exam-style practice questions

Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

Original4 marksAn organisation chart shows a manager with eight people reporting directly to her, and below them three levels of staff. (a) State the manager's span of control. (b) Explain what is meant by the chain of command in this business.
Show worked answer →

(a) The manager's span of control is eight, because eight people report directly to her. (Span of control is the number of subordinates a manager is directly responsible for.)

(b) The chain of command is the line of authority down which instructions pass from the top of the organisation to the bottom, and along which staff report upward. In this business it runs from the top down through the manager and then through the three levels of staff below, so each level passes orders down and reports to the level above.

Markers reward correctly stating the span of control as eight and explaining the chain of command as the line of authority and communication from top to bottom of the organisation.

Original8 marksA growing company is deciding whether to keep its tall organisational structure or move to a flatter one with fewer levels. Discuss the advantages and disadvantages of moving to a flatter structure.
Show worked answer →

Explain the change. A tall structure has many levels and narrow spans of control; a flat structure has fewer levels and wider spans of control, so removing layers makes the structure flatter.

Analyse the advantages. Flatter structures shorten the chain of command, so communication is faster and clearer with fewer levels to pass through. They cut management costs by removing layers of managers, and wider spans push more delegation down to staff, which can improve motivation as workers gain responsibility.

Analyse the disadvantages. Wider spans of control mean each manager supervises more staff, so they may be stretched and less able to support each worker. Some staff lose promotion steps as layers disappear, which can lower motivation, and the change itself can be disruptive and create job losses among middle managers.

Reach a judgement. A flatter structure suits the firm if it wants faster communication, lower costs and more empowered staff, and if managers can cope with wider spans. If close supervision is needed or managers are already stretched, a flatter structure may harm control. A balanced answer recommends flattening only if managers can handle wider spans and the firm values speed and delegation over close control.

Markers reward explaining tall versus flat, analysing faster communication, lower cost and delegation against wider spans and lost promotion, and a justified judgement.
