Eficiência qb

 

Li no FT do passado dia 5 de Dezembro o artigo intitulado "The truth about efficiency":

"The difference between medicine and poison lies in the dose. This truth speaks directly to government reform. As Washington prepares to launch an efficiency crusade, we must remember that efficiency, wrongly dosed, can sicken the very system it means to improve. [Moi ici: Recordo os hospitais-cidade, por exemplo]

...

The forgotten French engineer Jules Dupuit understood this problem. In the early 1800s, before the term "scientist" existed, engineers were the high priests of social arithmetic. As Paris's chief engineer in 1850, he faced a practical issue: how could public projects be efficient while maximising social benefits?

His answer came not through cost-cutting but by understanding how people valued and used the services. Whether maintaining roads or setting water prices, Dupuit recognised that efficiency in public systems had to balance market incentives with fairness and technical requirements with social needs. 

...

Dupuit's engineering mindset helped him see that these apparent inefficiencies weren't flaws but features. They helped people make trade-offs between time and money when choosing which bridge to cross, for example.

Society seeks efficiency, often without a deep knowledge of what it is. Efficiency performs endless mutations - now time, now money, now speed, now productivity, now lay-offs, now accountability, now market share, now GDP.


...

Success requires prudence - knowing not just how to be efficient but when to let efficiency yield to other parameters of good governance. When we privilege efficiency above all else, we create brittle systems prone to catastrophic failure."

A eficiência, quando procurada sem equilíbrio, pode enfraquecer os sistemas, tornando-os susceptíveis ao fracasso. As redundâncias incorporadas e as margens de segurança (slack), muitas vezes vistas como ineficiências, são cruciais para a resiliência.

As PMEs, tal como os governos, enfrentam ambientes voláteis. A optimização excessiva em termos de eficiência de custos pode deixá-las vulneráveis ​​a perturbações (por exemplo, rupturas nas cadeias de abastecimento, alterações no mercado). 

A manutenção de stocks de reserva, "buffers", de fornecedores diversificados e de métodos operacionais alternativos pode parecer ineficiente, mas garante a continuidade do negócio durante as crises.

A visão de Dupuit sobre como equilibrar custos, justiça e necessidades sociais é de aplicação directa para as PME, que devem tomar decisões centradas nos clientes-alvo e que promovam a lealdade e a sustentabilidade da relação. Clientes não são súbditos/servos sujeitos aos caprichos das empresas
