Management: a century of theory, from control to agility

Two teams, same company, same pay, same tools. One crackles with energy, the other counts the hours. The only variable that truly differs is the manager. According to Gallup, the quality of the boss alone explains at least 70% of the engagement gap between two teams. Your Monday-morning mood, in other words, depends less on your job than on the person you report to.

Why management concerns you, wherever you work

Management is not a topic reserved for executives. Anyone who works feels its effects every day: how their time is organised, how their goals are set, how their effort is recognised. These choices do not fall from the sky. They flow from theories built over more than a century, tested in factories, offices and start-ups on every continent.

One figure captures the stakes. Gallup estimates that low engagement at work costs the global economy around 10 trillion dollars a year, close to 9% of world GDP. This is not an abstraction: it is lost productivity, stalled projects, talent walking out the door. To understand management is to understand why some organisations move forward while others get stuck.

The paradox is this. Never has the data so clearly shown the weight of the manager, and never have companies tried so hard to reduce their number. To grasp this tension, we must first return to the question management has asked since its beginnings: should you control people or trust them?
