The document outlines eight signs of incompetent managers: poor communication skills, weak leadership capabilities, inability to adapt to change, poor relationship building, ineffective task management, insufficient production, poor development of others, and neglect of personal development. It provides examples for each sign and recommends using assessment tools to evaluate managers, provide feedback, create development plans, and potentially redeploy managers if needed. The overall message is that identifying and addressing incompetence among managers can improve an organization.
