Why narrow span of control is expensive?

A narrow span of control is expensive because it requires more managers to oversee fewer employees, leading to higher labor costs. This structure can result in increased administrative overhead, as more management layers can slow down decision-making and reduce operational efficiency. Additionally, it may limit the potential for employee autonomy and empowerment, which can stifle innovation and productivity. Ultimately, the financial burden of maintaining a narrow span of control can outweigh the benefits of close supervision.
