度量即管理，管理方能成事。
What gets measured gets managed.
— Peter Drucker
【English explanation】
Peter Drucker’s famous management principle highlights that measurement brings accountability and control. When you measure something, you make it visible, trackable, and improvable. Without measurement, effort remains blind and unmanaged; with it, progress becomes concrete and achievable.
【中文解读】
彼得·德鲁克著名的管理原则强调：衡量带来问责与控制。当你衡量某件事物时，它就变得可见、可追踪、可改进。没有衡量的努力是盲目的；有了衡量，进步就变得具体而可实现。
