Authority, Delegation and Centralisation

The way authority is distributed within an organisation fundamentally shapes how decisions are made, how quickly the business can respond to change, and how motivated employees feel. Understanding the key concepts of span of control, hierarchy, delegation and centralisation is essential for analysing organisational design.

Key Concepts

Hierarchy

A hierarchy refers to the arrangement of people within an organisation according to their level of authority. A hierarchical structure has multiple layers of management, each with progressively more authority as you move upward.

• Chain of command — the path along which instructions and communication flow from the top of the hierarchy to the bottom
• Levels of hierarchy — the number of layers between the most junior employee and the most senior

Span of Control

Key Definition: The span of control is the number of subordinates (employees) directly reporting to a single manager.

Span of Control	Characteristics	Implications
Narrow (e.g., 2-4 subordinates)	Close supervision; more layers of management	Tight control; slower communication; higher management costs
Wide (e.g., 8-12+ subordinates)	Less direct supervision; fewer layers of management	Greater autonomy; faster communication; risk of overload

The optimal span of control depends on:

• Nature of the work — routine tasks can be supervised with a wider span; complex tasks require a narrower span
• Skills and experience of subordinates — highly skilled, experienced workers need less supervision
• Management style — democratic managers may manage wider spans; autocratic managers may prefer narrower
• Geographic dispersion — managing remote teams may require a narrower span for effective communication
• Use of technology — project management software and communication tools can support wider spans

Tall vs Flat Organisational Structures

The relationship between span of control and levels of hierarchy creates either tall or flat structures.

Tall Structures

• Many levels of hierarchy
• Narrow spans of control
• Clear career progression paths (many rungs on the ladder)
• Close supervision and control
• Slower communication and decision-making (messages pass through many layers)
• Higher management costs (more managers needed)
• Risk of distortion as information passes through multiple levels

Flat Structures

• Few levels of hierarchy
• Wide spans of control
• Fewer promotion opportunities (may affect motivation)
• Greater employee autonomy and empowerment
• Faster communication and decision-making
• Lower management costs
• Risk of managers becoming overloaded with too many subordinates

Modern business trends generally favour flatter structures, driven by the desire for speed, flexibility and employee empowerment. Delayering (removing levels of hierarchy) is a common restructuring strategy.

Delegation

Key Definition: Delegation is the process of entrusting a task or responsibility to a subordinate while retaining overall accountability.

Delegation is not the same as abdication (simply handing over and walking away). The manager who delegates retains accountability for the outcome and should provide appropriate support and resources.

Benefits of Delegation

Benefit	Explanation
Frees up senior management time	Managers can focus on strategic priorities rather than routine tasks
Develops subordinates' skills	Employees gain experience and confidence by taking on new responsibilities
Improves motivation	Delegation signals trust and gives employees a sense of ownership (linked to Herzberg's motivators)
Speeds up decision-making	Decisions can be made closer to the point of action, without waiting for senior approval
Succession planning	Prepares employees for future promotion by exposing them to higher-level responsibilities
