The Goal, by Eliyahu M. Goldratt examines the life of an American plant manger in his quest to find out what exactly the goal of a plant manager is and how to go goal. Along the way towards realizing the goal, the plant manager is forced define and understand the theory of constraints. It is important to understand the theory of constraints for the manager to be able to identify what restrictions are being various operations and to know how to reverse their affects. In this particular the manager having to continually deal with orders being finished late customers and an irate employer in order to realize that serious within his plant. Once the goal, which inevitably turns out to be money, is found, it is imperative to figure out how to express the goal in the form of a measurement.
Three measurements are able to not only express the goal of making money, but also make it possible for the manager to develop operational rules for running his plant. These measurements are: throughput, inventory, and operational expense, and everything that the manager manages in his plant is covered by them. Still, the manager must do much thinking and research in order to figure out just how to express his goal in terms. In addition to expressing the goal, the manager is troubled by whether employees, robots, and machinery actually need to be running at all times. At managers seem to think that an idle worker is an unproductive worker, but Goldrattshows us that in reality a plant in which everyone is working all the time is very inefficient. The manager in the book soon comes to realize that machines don't run themselves -- it takes people to create excess inventory, so sometimes when a worker is taking a break, thereby leaving a machine idle, it's actually a good thing.
One huge problem that often arises in a plant such as the one Goldratt has lead us through is distinguishing between two resources. One is the bottleneck which is when many operations are feeding their output into one operation whose capacity is less than the combined capacities of the operations that provide input, leaving units to queue to be processed. If bottlenecks can be improved then productivity will increase until the output rate of the bottleneck is equal to that of the output rate of it. The second resource is the non-bottleneck which is any resource whose capacity is greater than the demand placed on it.
In the Goal it can be seen that for the plant manager is the bottleneck and how to make the flow through the bottleneck only slightly less than demand. First and foremost, every manager and future manager should definitely sit down and read this book. Even if it does not of characteristics of a particular plant, the basic concepts that The Goal discusses can to nearly every manager of any kind of business. Learning to deal with such things has bottlenecks, excess inventories, and the theory of constraints is something struggle with.
Also, Goldratt teaches that, contrary to the belief of in the world, capacity should never be them the quickest and and the lowest cost. The engineering department is in charge of such things as approving which parts go through heat treatment and making sure that everything is performed up to code for top and performance. Though The Goal is more or less directed toward managers, and even more specifically plant managers, it can basically be read and enjoyed by anyone. Not only does it show how to manage a plant, but it also show how to manage ones' life. Though for many, a successful career signifies a successful life, we have to remember friends are also a sign of success and that they can be just as big contributors -person's rise to the top as his co-workers.
In order to deal with such a manager consults a mentor who keeps him constantly thinking and researching possible remedies to the many problems that are occurring within his plant. The Goalisn't just a book, it's a novel. Goldratt takes his reader through an enjoyable the work life and the personal life of an American plant manager. Through this easy-to-read story I was able to better understand how inventory and how it goes through both bottlenecks and non-bottlenecks has such a huge impact on all aspects of a plant. And just like the plant manager in the book, I was always under the impression that idle workers meant trouble for the business.
I never considered its impact on inventories and therefore on productivity. This book really opened my eyes to things such as this -workings of a manufacturing plant... something that I had little exposure to before. One thing that I did not find easy to understand was the theory of constraints, though Iknow this is probably a huge part of the novel. I realize that there are a plant's operations, but I'm still unclear about how the theory of constraints was involved in this particular situation.
The Goal shows that there is an answer to all questions -- it's just a matter of asking yourself the right questions and then logical thinking processes in order to come up with those answers. In addition The Goal is about not just one manager finding the answer to one goal, but about a group of people, rather a team, both on the job and at home, working together and to meet a series of common goals. And, finally, Goldratt teaches that things as they seem and sometimes we have to for goe traditional methods and take a chance with new ideas, thinking, and innovations. Basically, we have to do what it takes to reach the goal..
