Over-optimizing systems can reduce robustness and lead to unintended consequences
Key points
- High efficiency can reduce system robustness.
- Optimization can lead to insufficient slack.
- Narrow definitions of "best" cause issues.
- Computers expanded optimization capabilities.
The Efficiency Paradox
The article highlights a paradox where the relentless pursuit of efficiency can lead to negative outcomes. For instance, high hospital bed occupancy, while efficient in a business sense, leaves no reserve for surges in demand, such as during flu season. This can result in patients being treated in corridors due to a lack of available beds.
The Role of Slack
A key point is the importance of 'slack' within systems. What appears to be inefficiency, like an empty hospital bed on a quiet night or a gap between meetings, actually provides crucial resilience. This slack allows systems to recover from unexpected events and cope with challenging conditions, rather than collapsing under stress.
Optimization and its Traps
Mathematicians refer to the pursuit of efficiency as optimization, aiming to minimize or maximize specific variables like cost or time. While computers have significantly expanded the scope of optimization, leading to societal gains, there are inherent traps. One trap is weakening a system's robustness by eliminating too much slack. Another is defining "best" too narrowly, which can lead to unforeseen problems, as illustrated by the urban planning of Milton Keynes.

Focusing solely on efficiency can weaken a system's ability to handle unexpected events, as seen with hospital bed occupancy. This pursuit of optimization, while beneficial in many areas, carries risks such as reducing slack and defining "best" too narrowly. These traps can lead to systems that perform poorly under stress or create new problems.
