Organisational structures

How a business arranges its people determines how decisions are made, how quickly information flows, and how empowered staff feel. Edexcel 1BS0 covers four distinctions.

Hierarchical vs flat structures

Hierarchical (tall) structures

Many layers of management; a clear chain of command from CEO down to front-line staff. Common in large organisations (banks, NHS, civil service, military).

Pros: clear roles and authority; promotion pathways; specialist managers. Cons: slow decision-making; communication distorts as it moves through layers; expensive (many managers).

Flat structures

Few management layers. Typical of start-ups, agencies, tech firms.

Pros: fast decisions, cheap (fewer managers), staff empowered, direct communication. Cons: managers have wide span of control (harder to support each report); fewer promotion opportunities; can become messy as the business grows.

Centralised vs decentralised

Centralised

Decisions concentrated at the top (HQ). Branches/staff follow instructions. Used by McDonald's, supermarket chains.

Pros: consistency across the business; strong cost control; clear strategic direction. Cons: head office may not understand local needs; demotivates branch staff; slow to respond to local change.

Decentralised

Decisions delegated to local managers/teams. Used by Pret (managers tweak product mix to local market), Burberry regional teams.

Pros: faster local response; motivates local managers; better market knowledge. Cons: inconsistency; harder cost control; risk of strategy drift.

Delayering

Delayering is removing one or more layers of management to flatten the structure. Aim: cut cost, speed up decision-making, empower staff.

Risks: redundancy costs, lost expertise, wider span of control overwhelms remaining managers.

Chain of command and span of control

• Chain of command — the line of authority running top → bottom. Long in tall structures, short in flat.
• Span of control — the number of staff reporting to one manager. Wide in flat structures, narrow in tall.

Trade-off: a wide span makes management cheaper but harder to coach each report; a narrow span supports staff but adds management cost.

Impact of digital communication

Email, Slack, Teams, video calls and project software flatten structures because:

• Information bypasses hierarchy — anyone can email anyone.
• Status updates are visible across the org without going through a chain.
• Remote/hybrid working makes traditional offices and management proximity less critical.

This has accelerated delayering in many sectors over the past decade.

Edexcel exam tip

When recommending a structure, match it to (a) business size, (b) market environment (stable vs fast-changing), and (c) the nature of decisions (consistent global vs local responsiveness). One-size-fits-all answers lose marks.
