Goldratt's "The Goal"
“The Goal” by Goldratt is a book about the Theory of Constraints, TOC. It is about the behavior of manufacturing facilities. It deals with bottlenecks that are the manufacturing constraints and the variability that creates them. The book states that a manufacturing organization cannot run at 100% and that you cannot balance the assembly line. It seems that your efforts for efficiency must be focused on the worst bottleneck. The loss caused by a bottleneck is a loss for the entire system. Focusing on improving the throughput of the bottleneck increases the flow for the entire manufacturing line. If there is a bottleneck, then all other areas are capable of excess capacity. Don’t try to improve non-bottlenecks, as it is a waste of time and effort. The TOC integrates into Total Quality Management, TQM, except for one main theory. TQM supports continuous improvement of the system while the TOC does not support continuous improvement of every process. The TOC says that we must focus on the constraint.
Q: What is the Theory of Constraints about?
A: Developed by Dr. Eliyahu M. Goldratt, TOC states that any system has at least one constraint. Otherwise, it would be generating an infinite amount of output. Bearing this in mind, TOC is easily explained through use of the "chain" analogy - "a chain is only as strong as its weakest link." If we look upon our organization as a chain, where each department is a "link" in the chain, what constrains our organization from achieving its goal? Only through addressing the weakest link, the constraint, can substantial improvements be made. In other words, if the constraint dictates the pace of an organization's ability to achieve it's goal, it makes sense that addressing the constraint will allow the organization to achieve a substantial rate of throughput faster.
There are five steps in applying TOC:
1. Identify the system's constraints. Of necessity this included prioritization so that just the ones that really limit system progress toward the goal.
2. Decide how to exploit the system's constraints. Once we have decided how to manage the constraints within the system, how about the majority of the resources that are not constraints? The answer is that we manage them so that they just provide what is needed to match the output of the constrained resources. We NEVER let them supply mo...

...achine was running and an operator on your line was to set it up if it went down, you could take your break at your convenience. A few months went by and new coaches were hired. They decided they wanted to closely monitor the operator to see when they took their breaks and for how long. The decision was made to stop the machines when you go on your break and/or lunch. The new coach obviously wanted to make a good impression and bring something new to the table. They changed our staggered breaks to scheduled breaks. The results after a few weeks showed production was down and efficiency was at a record low. It showed machines were not running at full capacity for a tour. Immediately their superiors decided we would go back to the staggered lunches and breaks. The downtime was then reduced and our departmental efficiency went up. They realized it was not as important to monitor the person, as it was to have the machine running. Now I know this does not stand up to the problems Alex and his staff faced with UniCo but this is what I face everyday. I found a case study that was used at the TOC World 2000 Seminar in St. Paul MN last year. I thought I would include it for your enjoyment
Continuous improvement (CI) refers to a philosophy consisting of improvement activities that increase successes and reduce failures in a production process (Bhuiyan & Baghel 2005, p. 761). It involves activities and processes that focus on continuous and incremental innovation (Bessant et al., 1994, p.17). CI is a new approach that enhances productivity, performance, and achieves competitive advantage needed in the highly competitive industries. It may also serve as a complementary approach to other quality improvement initiatives such as total quality management (TQM) (Pike, Barnes, & Barnes 1995, p. 23; Larson 2003; Lassen, Gertsen, & Riis 2006; Oakland 2007, p. 227). The purpose of this research is to explore the application of production systems engineering methods in the CI at manufacturing plants.
The Goal is a book that has an immense support on improvement, which will undoubtedly encourage the Total Quality Management terminology when trying to built up and improve their productivity. However, the Theory of Constraints also plays a very important role in this book, because it guide us to not only focus on the improvements of the business as a whole, but also to focus intensively on the constrains, “ Herbies”, or bottlenecks.
This would therefore have a knock-on effect to reduce the overall production sites and effectiveness of the other parts of the company. The practices already in place help the Group to achieve its objectives by; Continually reviewing its source of supply-This meets the objective of focus on performance, supply and cost Continually applying quality management- This meets the objectives of absolute attention to compliance and team work and talent expression Continually benchmarking other companies- This meets the objective of focusing on their own performances to meet the aim of being a world leader.
Defining the problem begins with understanding how the actors are inclined to act and how the actors could interact. It also identifies tensions of the current conditions and the end-state. The problem statement explains how the operational variables will resist change and how areas of action can transform existing conditions to the desired end-state.
Basically, the focus of the recommendations is to reduce the disparities between the capacities of the processes involved. Ideally, their outputs must be equal if not, similar to the preceding and succeeding procedures in order to achieve an efficient manufacturing process.
“The Goal” is as it vividly explains, is a book on achieving goals. Eliyahu Goldratt, world famous Israeli physicist turned business consultant, the creator of the “Theory of constraints”, in his work “The Goal”, explains a lot about managerial skills, to achieve higher productivity and efficiency, in a simple and lucid manner.
When reading the book The Goal written by Eliyahu Goldratt, there were many lessons that I learned in order to have a clear and concise understanding of a positive level of productivity in a company. To have a positive level of productivity there are may components that are taken into consideration. Understanding what it actually means to be productive and how to increase the level of productivity by knowing the actual goal of the company that is trying to be reached and the components that go into the process of being productive. There are many factors that contribute to the level of productivity and being able to identify these factors is the key ingredient to having a successful level of productivity.
Business improvement techniques such as Six Sigma, Lean Management, Theory of Constraints (TOC) and Continuous Process Improvement (CPI) are successful and accepted worldwide. Many successful firms, for instance Toyota uses production planning techniques to achieve world class quality output. AGI in this paper illustrates the before and after stages by implementing various business improvement techniques to achieve the desired output. Also, high end business such as, U.S Navy implements the integrated blend of TOC, Lean and Six Sigma approach- “AIR” to eliminate the problems arising from uncertainty and inefficiency. Furthermore adding speed and direction to their project. On the other hand, Youngman demonstrates the production planning using
Explain the importance of defining the objectives, scope and success criteria of the decisions to be taken
After the systems planning is complete, the next course of action is the systems analysis phase. This phase includes defining the requirements of the system. This means that the team must conclude what the system needs to do in order to satisfy the users. This is done by forming a requirements...
The Goal of any business is to obtain maximum results in the most efficient manner while at the same time providing your customer with the quality product they desire. Often times this process is made difficult with waste or anything that clogs the process unnecessarily. Henry Ford aimed to eliminate this waste through looking at his manufacturing pro...
Define the current situation - break down problem into component parts, identify major problem areas, develop a target improvement goal
GM uses this system by containment, disposition, separation, and classification. Such a system guarantees that any outcome that does not comply with specified requirements is restricted from unintended use, restrained, and dispositioned by the administrators. Accompanied by this quality control is the verifying position where first-time quality and process capacity is advanced (Drew, 2011). Every team member is informed about any modifications in the production process and who and when to summon for assistance in the event of any quandary. Every team is also included in the problem solving to reach any improvement in goals.
“The Goal” is a book talking about challenges and problems that can face any plant manager. The story style used was very useful. I enjoyed the reading and gain more knowledge about the manufacturing operation. Many concepts and definitions were introduced such as the goal of any company and the its three measurements which are throughput, inventory and exponential expenses. Also, bottleneck and non-bottleneck resources.
Three distinct decision making processes are programed decisions, operations research, and non-programed decisions (Dunn, 2010). Programed decisions are those made routinely and are well-known to the person making the decision (Dunn, 2010). Often these issues have standard rules and regulations that encompass them (Dunn, 2010). As stated by Dunn (2010), “operations research is closely aligned with systems analysis and is defined as the use of mathematical models, analytical methods, or structured inquiry to analyze a complex situation and identify the optimal approach” (p. 44). The third decision making process is non-programmed decisions, which are out of the ordinary having no typical solution (Dunn, 2010).
