Optimising a part can damage the whole

Organisations are full of locally rational decisions that produce an irrational result.

One team reduces its cost by transferring work to another. A sales incentive wins customers the product cannot serve. A performance metric improves while the actual experience becomes worse.

This happens because each part is rewarded for its own output, not the health of the system.

Systems thinking asks us to follow the consequence beyond the boundary of a department. Where did the cost move? Which delay appeared elsewhere? What behaviour will this metric encourage over time?

The whole is not improved simply because every part can present a green dashboard.
