Scalar Chain and Gangplank: Shorten the Communication Path Without Losing Accountability

Communication · Executive Insight Brief · 235

Every relay needs a reason

Fayol’s scalar chain and gangplank separate the line of authority from the route information should take when vertical relay makes coordination too slow

Premise

Hierarchy solves one communication problem and creates another. A known line of authority clarifies who can decide, where responsibility sits, and how instructions and reports move. Yet interdependent work often cuts across the chart. When every cross-functional issue must travel upward to a common superior and then back down, managers become routing devices and information arrives late.

Henri Fayol’s scalar chain and gangplank expose this design tension. The scalar chain preserves an intelligible vertical line of authority. The gangplank, or passerelle, permits authorized direct communication across that hierarchy when the formal route would be inefficient, while keeping responsible superiors informed.
