"Efficiency is the ratio between input and output. It asks, what is the best output that I can get for the resources that I put in? For this required output, what is the minimum of resources that I must put in? If we think in terms of efficiency, we have to think in terms of input/output ratios.Não é comum encontrar quem me acompanhe na crítica à paranóia do eficientismo.
Efficiency means productivity. Efficiency means no waste. Efficiency means getting the best out of our efforts, energy and resources. What can possibly be wrong about that?
To begin with, efficiency looks at input and output and does not look at the customer.
There are further problems with the concept of efficiency. Efficiency is measurable at one point in time. While efficiency has to be measurable, what may happen in the future cannot be measured. So it is left out of any efficiency equation. You design a suspension system for the bumps it encounters right now, not for all the possible bumps it might encounter in the future. Efficiency has always got to look backward and historically. It seeks to maximize what is now being done and what is now known.
When the future turns out not to be exactly as predicted, which is usually the case, efficiency may actually have gotten us into trouble. Very efficient businesses are often very brittle. There is no cushion and no give, because there has been no waste and no slack. Bamboo scaffolding around major buildings in Hong Kong seems flimsy and insubstantial. In fact, it is very strong because it is flexible, and stresses and strains are shared all around.
Efficiency is often the enemy of flexibility, and in today’s business world, flexibility is becoming more and more important."
E aquele "Very efficient businesses are often very brittle" é uma das lições que se pode tirar do postal dos almoços grátis de 2008:
Quanto mais pura é uma estratégia maior a rentabilidade, mas também maior o risco se o mundo muda.
