Quotes from Eliyahu M. Goldratt

A propósito, el sentido común no es tan común, y el más alto elogio que podamos hacer de una cadena de conclusiones lógicas se llama «sentido común». Si hacemos esto, habremos sacado a la ciencia de su torre de marfil académica y la habremos colocado donde debe estar: al alcance de cada uno de nosotros, aplicable a lo que vemos a nuestro alrededor.

Bottlenecks temporarily limit throughput. Maybe your plant is proof of that. But they have little impact upon inventory." "It's completely the opposite, Hilton," I say. "Bottlenecks govern both throughput and inventory. And I'll tell you what my plant really has shown: it's proved our performance measurements are wrong.

if you're like nearly everybody else in this world, you've accepted so many things without question that you're not really thinking at all

When you are productive you are accomplishing something in terms of your goal

A bottleneck," Jonah continues, "is any resource whose capacity is equal to or less than the demand placed upon it. And a non-bottleneck is any resource whose capacity is greater than the demand placed on it.

Balance flow, not capacity.

productividad es el acto de acercar a la empresa a su meta. Las acciones que acercan a una compañía a su meta son productivas. Las acciones que no acercan a la compañía a su meta no son productivas.

Actually, the flow should be a tiny bit less than the demand.

You mean make them into non-bottlenecks," says Stacey. "No," he says. "Absolutely not. The bottlenecks stay bottlenecks. What we must do is find enough capacity for the bottlenecks to become more equal to demand.

bringing a company closer to its goal. Every action that brings a company closer to its goal is productive. Every action that

If you don't manufacture a quality product all you've got at the end is a bunch of expensive mistakes.

Open-minded people will not necessarily agree with me, not when my arguments don't make sense to them. But open-minded people do listen, and if I explain (and when it is important), they are willing to invest in reevaluating their cause-and-effect connections.

If you don't manufacture a quality product all you've got at the end is a bunch of expensive mistakes. You have to meet the customer's requirements with a quality product, or before long you won't have a business.

Ürünün deÄŸerini en baÅŸta pazar belirler" dedi Lou. "Bir ÅŸirket eÄŸer para kazanmak istiyorsa, ürünün deÄŸeri—bizim ona biçtiÄŸimiz fiyatsatt???m?z birim ba??na stoklara yap?lan yat?r?mla toplam iÅŸletme giderlerinin toplam?ndan daha fazla olmal?d?r.

Quality alone cannot be the goal. It's important. But it's not the goal.

Producing a quality product efficiently: that must be the goal. It sure sounds good. "Quality and efficiency." Those are two nice words. Kind of like "Mom and apple pie.

Science is simply the method we use to try and postulate a minimum set of assumptions that can explain, through a straightforward logical derivation, the existence of many phenomena of nature.

the goal is to make money, then (putting it in terms Jonah might have used), an action that moves us toward making money is productive. And an action that takes away from making money is non-productive.

Kanban system directs each work center when and what to produce but, more importantly, it directs when not to produce. No card—no production.

El me dijo que cuando la gente juzga que un cambio es bueno, lo acepta. Tu actitud hacia el cambio se modificó en el momento en que tomaste conciencia de sus efectos.

Adhering to the flow concept mandates the abolishment of local efficiencies. Ohno addressed this issue again and again in his books, stressing that there is no point in encouraging people to produce if the products are not needed in the very short-term. This emphasis is probably the reason that outside Toyota TPS first became known as Just-in-time production.7

Interesting, isn't it, that each one of those definitions contains the word money," he says. "Throughput is the money coming in. Inventory is the money currently inside the system. And operational expense is the money we have to pay out to make throughput happen. One measurement for the incoming money, one for the money still stuck inside, and one for the money going out.

All this is, if I understand it correctly, is a different way of doing the accounting. All employee time—whether it's direct or indirect, idle time or operating time, or whatever—is operational expense, according to Jonah. You're still accounting for it. It's just that his way is simpler, and you don't have to play as many games.

La meta sigue siendo la misma, pero podemos expresarla de otra forma, y que signifique lo mismo que esas dos palabras: "ganar dinero". -Bien
