The document discusses two principles of management: discipline and unity of command. It states that discipline involves obedience, respect for authority, and following rules. Managers should clearly explain rules, supervise effectively, reward obedience, and penalize non-obedience. This leads to achieving goals, efficiency, and good relations. Lack of discipline causes disorder. Unity of command means an individual receives orders from only one supervisor to avoid confusion and work effectively. Having multiple bosses leads to unclear responsibilities and inefficiency. Following these principles positively impacts performance and relations, while violating them reduces efficiency and causes confusion.
