Experienced managers are well aware of these complexities and uncontrollabilities, often feeling a deep sense of frustration and discouragement. To smoothly carry out their work, in addition to actively attending courses and enhancing their management knowledge, managers often come up with various strategies. I’ve encountered many supervisors who use militarized management, with one command and one action. This approach seems effective in the short term but tends to revert and even backfire due to human inertia in the long term, making it more complicated.
