There is a metaphor quietly shaping how we lead schools. Most of the time, we do not even notice it. If we see schools as machines, we try to fix them with tighter policies, sharper monitoring and new initiatives bolted on like replacement parts. When results dip, we assume something is broken. When behaviour slips, we assume something needs tightening. But what if schools are not machines? What if they are ecosystems? That shift in metaphor changes everything.
