The short
- Efficiency: Maximises output under known conditions.
- Blind spot: Removes buffers, slack, and optionality.
- Risk: Small shocks cascade into system-wide failure.
- Insight: Optimisation locks organisations into narrow paths.
- Lesson: Resilience requires inefficiency.
Why efficiency feels like intelligence
Efficiency is measurable. It shows up in margins, dashboards, and quarterly reviews.
Leaders reward it because it feels rational: less waste, tighter processes, clearer accountability.
Over time, efficiency stops being a tool. It becomes an identity.
The problem with local optimisation
A local optimum is the best solution within a narrow frame.
It works — as long as the environment stays the same.
But when conditions shift, locally optimal systems have nowhere to move.
What efficiency quietly removes
To become efficient, organisations eliminate:
- redundancy,
- overlap,
- idle capacity,
- and dissent.
Each removal improves short-term performance. Together, they erase recovery paths.
Why efficient systems fail faster
When stress appears, efficient systems have no slack.
Errors propagate instead of being absorbed. Recovery requires redesign, not adjustment.
The system does not bend. It breaks.
Slack is not waste
Slack looks irresponsible in spreadsheets.
In reality, it is insurance:
- time to think,
- capacity to respond,
- space for learning.
Slack turns shocks into signals instead of disasters.
The takeaway
Efficiency is not strategy. It is optimisation under assumptions.
Strategy preserves freedom of movement — especially when assumptions fail.
