Principles of Organization: Hierarchy, Span of Control, Unity of Command, Delegation and Centralization/Decentralization
What the domain tests
This domain tests whether you can use organizational principles analytically rather than recite them: hierarchy, span of control, unity of command, delegation, and the centralization–decentralization continuum. Questions often ask you to spot a structural defect in an office and prescribe a principle-based fix.
Core rules and concepts
- Hierarchy is the scalar chain of superior–subordinate relationships; it fixes authority, communication and responsibility.
- Span of control is the number of subordinates directly supervised. A narrow span gives closer supervision but adds levels and delays; a wide span speeds communication but risks overload. Graicunas showed that relationships grow faster than headcount.
- Unity of command means one subordinate should receive orders from one superior for a given task; Fayol treated dual command as a source of confusion.
- Delegation is the transfer of authority to perform a task, not the surrender of ultimate responsibility. It requires assignment, authority, accountability and creation of responsibility.
- Centralization concentrates decision authority at the top; decentralization disperses it. Deconcentration is only a field-office shift, not full decentralization.
Worked example
A collector directly supervises 14 branch heads and also creates two additional reporting layers. The span is too wide at the top: 14 direct reports plus inter-unit coordination overload the collector. A principled fix is to group branches under three senior supervisors, clarifying unity of command and delegating routine approvals, while the collector retains budget and disciplinary decisions. This narrows the span without abdicating responsibility.
Traps that cost marks
There is no universal ideal span; it depends on task complexity, staff competence and technology. Delegation is not abdication. Staff units advise; they do not dilute the line's unity of command. Decentralization is not the same as deconcentration or privatization.
