How the chain of command works
Every solid line on an org chart is one link in a chain of command. Instructions and delegated authority flow down it; information, requests for decisions and escalations flow up. In the chart above, a sales rep’s request for a special discount goes to the sales lead, who can approve small ones and pass bigger ones to the head of sales.
Unity of command
The French engineer and management theorist Henri Fayol listed “unity of command” among his fourteen principles of management in Administration Industrielle et Générale (1916): each employee should take orders from one superior only. Two bosses giving conflicting instructions is one of the fastest ways to stall work, which is why most organisations keep one solid reporting line per person.
Scalar chain and “gangplank”
Fayol also described the scalar chain, the unbroken line from top to bottom, and noted that strictly following it can be slow. His “gangplank” lets two people at the same level in different branches (say, Kim in operations and Leo in sales) deal with each other directly, as long as their managers know. Modern cross-functional work runs on this idea.
Chain of command examples
- Military: private → corporal → sergeant → lieutenant → captain, and upward. The most rigid and explicit chain of command, because clarity under pressure matters.
- Hospital: staff nurse → charge nurse → nurse manager → director of nursing → chief nursing officer. See our hospital org chart template.
- Retail store: sales associate → shift supervisor → assistant manager → store manager → district manager. See the retail template.
- Startup: often just engineer → CTO → CEO. Short chains are one reason small companies move fast.
Long chains vs. short chains
The length of the chain is set by span of control: narrow spans stack more layers, so the chain gets longer. Long chains give close oversight but slow decisions and distort messages as they pass through each layer. Short chains are fast but put more on each leader.
