Organisational design: hierarchy, span of control and structures

Key terms

• Hierarchy: the levels of authority in an organisation, from the top (directors) to the bottom (operatives).
• Chain of command: the line through which instructions pass down and information passes up, from superior to subordinate.
• Span of control: the number of subordinates who report directly to one manager. A wide span means many; a narrow span means few.
• Centralised: most decisions are taken at the top (head office). Consistent, fast top-level decisions and tight control; but slower response to local conditions and less motivating for junior staff.
• Decentralised: decision-making authority is passed down to lower levels or local branches. Faster local decisions and more motivated staff; but less consistency and control, and needs capable managers.

Tall, flat and matrix structures

• Tall structure: many levels of hierarchy, long chain of command, narrow spans of control. Close supervision and clear promotion paths, but slow communication, more managers (higher cost), and staff may feel remote from decision-makers.
• Flat structure: few levels, short chain of command, wide spans. Faster communication, lower management costs, more responsibility for staff; but managers can be overloaded and there are fewer promotion opportunities.
• Matrix structure: staff are organised in project teams drawn from different functions (marketing, finance, operations), so each person reports to a functional manager and a project manager. Encourages cooperation, uses expertise across departments and suits complex projects; but having two bosses can cause confusion and conflict, and it is costly to coordinate.

Delayering is removing one or more levels of hierarchy, making a structure flatter.

Impact on efficiency and motivation

• Efficiency: flat structures cut management costs and speed decisions; tall structures may slow communication and distort messages passed through many levels; matrix structures share expertise but can duplicate effort.
• Motivation: wide spans and decentralisation give staff more autonomy and responsibility (linking to Herzberg's motivators and Maslow's esteem needs); tall structures provide promotion opportunities but can make staff feel controlled.

The right structure depends on the size of the firm, the skills of staff, the nature of the work and the leadership style.

Worked example

A company has 6 levels of hierarchy. The managing director has 4 direct reports. It removes 2 levels and increases spans of control. Analyse the effects.

1. Delayering creates a flatter structure with wider spans.
2. Efficiency: fewer managers' salaries and faster communication.
3. Motivation: more responsibility for remaining staff may motivate; fewer promotion steps and job losses may demotivate.
4. Risk: remaining managers may be overloaded and supervision weakened.

Answer: Lower costs and faster decisions, but overloaded managers and fewer promotion paths: the overall effect depends on staff skills and how it is managed.

Check yourself

1. A supervisor has 12 staff reporting directly to her. This number is her
   • chain of command
   • level of hierarchy
   • delegation ratio
   • span of control
   Show answer

   span of control. Direct reports = span of control.

2. Which is a feature of a tall organisational structure?
   • Few levels with wide spans of control
   • Many levels of hierarchy with narrow spans of control
   • Staff in project teams with two managers
   • No chain of command
   Show answer

   Many levels of hierarchy with narrow spans of control. Tall = many levels, narrow spans.

3. What is the main drawback of a matrix structure?
   • It prevents cooperation between departments
   • It has the longest chain of command
   • It cannot be used for projects
   • Staff may have two bosses, causing confusion and conflict over priorities
   Show answer

   Staff may have two bosses, causing confusion and conflict over priorities. Dual reporting lines.

4. Explain one advantage of a flat organisational structure.
   Show answer

   With fewer levels of hierarchy, communication between the top and the shop floor is faster and less distorted, and fewer managers are needed, so costs are lower.. Short chain of command: faster communication, lower cost, more autonomy.

5. A retail chain lets each store manager choose local promotions and stock lines. This is an example of
   • centralisation
   • a tall structure
   • decentralisation
   • a narrow span of control
   Show answer

   decentralisation. Decisions are passed down to local managers.

6. Explain one risk of delayering for a business.
   Show answer

   Remaining managers have wider spans of control and may become overloaded, so supervision weakens, and fewer promotion opportunities may demotivate staff.. Overloaded managers, weaker supervision, fewer promotion steps.

7. The route through which instructions are passed down an organisation is the
   • span of control
   • matrix
   • chain of command
   • person specification
   Show answer

   chain of command. Superior to subordinate.
