Scalar chain
The scalar chain is the formal line of authority connecting the highest and lowest organisational levels. It identifies reporting relationships and helps allocate responsibility, escalation and accountability. More layers can lengthen this chain and slow communication, although suitable direct or cross-functional channels can improve coordination. The formal chain does not describe every informal conversation or specialist advisory relationship.
Worked example
A purchasing clerk reports to a supervisor, who reports to the procurement manager and then an operations director. A major supplier failure follows the agreed escalation route, while routine information may be shared directly with production colleagues.
Common mistake
Do not confuse the length of the chain with span of control. One concerns successive authority levels; the other concerns the number of direct reports.
