“The Goal” by Eliyahu Goldratt. It sold out in 6 million copies in 30 languages. And it’s an explanation inform of a novel of how the Theory of Constraints applies in a factory. So, what’s the basic principle of it all? The Goal Book questions and answers will reveal the principles in this summary. Well, it’s based on the idea that in today’s world. The flexibility in the goal novel will blow your mind because it adjusts itself most probably to the business. You can no longer balance a plant correctly. You cannot distribute the work evenly throughout the system. So that everybody has just enough work. Because the work is not equally distributed, the Goal Book Summary begins here:
The Goal Key Concepts
The critical concepts of concentrating on the inclusive system’s goal, recognizing and manipulating constraints (The Five Focusing Steps), and using a systematic tactic to enhance (The Thinking Process) all balanced on the clue of enlightening output are exemplified throughout the novel.
The Goal Book Summary Beginning
The Goal Book analysis: You can represent the factory in this way where, for instance, that several tanks have water flowing through them. The diameter of the pipes between the tanks is different because the capacities are various. Of course, this means a resource with the most miniature tube, a bottleneck in the system. So, the Theory of Constraints in production where it was born and in other subjects is all about how you manage this system? The production management system calls the Drum Buffer Rope. Therefore, The first thing is that which identifies the resource that is the constraint. Herein red in the middle, for example, ‘s sake and the first thing one does is exploit it properly.
We have what we call the drum, and in fact, that is the planning scheduling system of the factory. And what is particular about it is that you focus on just that one resource, the bottleneck. You decide how you’re going to use it best according to the order book—for instance, saying that this work order did at that particular time. And that’s the first step to ensure we use that resource ideally, and the second step is the Rope.
The Goal Book Summary Mid
The Rope is this mechanism to launch the factory material. Let us assume that the three operations in front of the bottleneck take two days. For instance, well, if we planned a particular work order in four days here. It takes two days to get work done in front of it. Well then, we have to launch the raw materials in two days. So that would be the simple mechanism, but of course, if we do this, it won’t work because of any breakdowns or fluctuations or disturbances here. The product will end up late, and you won’t be able to meet the schedule, so the Buffer.
Therefore, A buffer is inserted just in front of the bottleneck, and this is a time buffer. It’s not a parts buffer. It’s a time buffer, and it could be one day. So in this example, we might say we’re going to protect the bottleneck against one day’s disturbances in front of the jam. Therefore, we would say, well, if I’m going to do it in four days. I need one day of protection and two days to get the work done. I’m going to launch it tomorrow in one day. This ensures that all this part of the factory is under control. There is a second buffer right at the end.
Its purpose is different to ensure that any disturbances in the non-bottle necks. After the constraint, don’t impact the date you promise to the client. Therefore, if you think back to the tank system, we want to make sure we don’t fill the factory up with a working process. And only keep a little bit of work in process in front of the bottleneck to ensure that the backup never stops. However, The strategy in terms of long-term improvement is the Five Focusing Steps; the first point is to identify the constraint or the constraints in the system. Therefore, The second idea is to exploit them and make sure that you use them as much as possible to maximize your throughput and sales.
Its third point is subordinate, subordinate everything else that’s what we’ve seen with the Rope as to say that non-bottlenecks will not work according to their potential. However, according to the constraint in the system requires, that isn’t easy, of course, because that means you have to break or reconsider all your local optimums. Therefore, I repeat, the non-bottlenecks will not work according to their potential but according to the constraints required.
The Goal Book Ending
Finally, once you’ve got that set going, you could consider elevating the constraint’s performance by investing in more machinery or going two shifts to three shifts or whatever. If you do this thing and increase the bottleneck’s capacity, the backup might move somewhere else in the factory. However, If that happens, you go back to step one. You find out where it’s gone, and you keep this process going. That’s basically what the Theory of Constraints in production is all about. Suppose you want to learn more about it.
