When communication occurs between members at the same level we describe it as lateral. Lateral communication saves time and facilitates coordination. Some lateral relationships are formally sanctioned. More often, they are informally created to short-circuit the vertical hierarchy and expedite action. Because strictly adhering to the formal vertical structure for all communications can be inefficient, lateral communication occurring with management’s knowledge and support can be beneficial. But dysfunctional conflict can result when formal vertical channels are breached.
