What this dot point is asking
AQA wants you to explain the elements of organisational structure, distinguish tall and flat structures and centralisation from decentralisation, and assess how structure affects motivation and efficiency. Be precise with the key terms, because several look similar and examiners reward exact definitions.
Elements of structure
These terms interlock: a tall hierarchy with many levels tends to have narrow spans of control and a long chain of command; a flat hierarchy has wide spans and a short chain. Getting them straight is half the marks on a definition question.
Tall and flat structures
Delayering is removing layers of management to flatten the structure, common as firms cut costs and push decisions closer to customers.
Delegation and centralisation
Delegation is passing authority (but not ultimate responsibility) down to subordinates. Done well it frees managers, develops staff and motivates them by meeting Maslow's esteem and Herzberg's responsibility needs, provided managers trust their teams and the staff are capable. Centralisation keeps decision-making at the top, giving consistency, tight control and economies in decision-making, but it is slow and can stifle local responsiveness. Decentralisation spreads decision-making down and out, giving speed, local knowledge and motivation, at some cost to consistency and control.
Impact on motivation and efficiency
A flatter, more decentralised structure with genuine delegation tends to raise motivation (more responsibility and autonomy) and speed up decisions, which suits skilled, self-directed staff and fast-moving markets. A taller, more centralised structure gives tighter control, clearer progression and consistency, but can demotivate and slow the firm down. The right design depends on the firm's size, the type of work, the capability of its staff and the pace of its market, so there is no single best structure.

AQA 20209 marksAnalyse the likely effects on a growing retailer of delayering from a tall to a flatter organisational structure. (9 marks)Show worked answer →
Delayering means removing one or more layers of management, which widens spans of control and flattens the hierarchy.
Benefits: lower management costs (fewer salaries), faster communication and decisions because messages pass through fewer layers, and greater empowerment as remaining staff take on more responsibility, which can raise motivation (Herzberg's responsibility motivator). For a growing retailer this can speed response to market changes and cut overheads.
Drawbacks: remaining managers have wider spans of control and may be overstretched, weakening supervision and support; staff losing layers may feel insecure or overloaded, hurting morale; and there are fewer promotion rungs, which can demotivate ambitious staff. Judgement: delayering helps if the firm has capable, self-directed staff and clear systems, but risks overload and poor control if rushed. Markers reward developed benefits and drawbacks tied to a growing retailer and a supported judgement.
AQA 20184 marksExplain why a wide span of control might reduce the effectiveness of a manager. (4 marks)Show worked answer →
A wide span of control means a manager directly supervises a large number of subordinates.
With many staff to oversee, the manager has less time for each one, so supervision, support, feedback and training all thin out. This can slow problem-solving, let mistakes go unnoticed, and leave staff feeling unsupported, all of which reduce the manager's effectiveness, especially if the work is complex or the staff are inexperienced. Markers reward the definition plus a clear chain from too many subordinates to reduced support to weaker performance.
