Goldratt explains how you can fully exploit management practices and apply them to the process of ongoing.

Subordinate everything else to the above decision. Start from simpler If-Then principles. It was home for eighteen years. He looks surprised to see me. One part of some sub-assembly is missing; it still has to be run through some other operation yet. Finally, and most importantly, I wanted to show that we can E.

In all these blocks, Y never determines throughput for the system. Throughput instead is determined by bottleneck X, or market demand. An hour lost at the bottleneck causes a loss in total throughput equal to the hourly capacity of that bottleneck. In other words, a loss in the bottleneck means a loss to the entire operation, and should be viewed with such gravity.

Other losses in effective throughput are also similarly costly. For example, feeding low-quality parts through the bottleneck will cause rejection later, leading to effectively lower throughput. While time lost from the bottleneck can be made up for by hurrying non-bottlenecks, any extra effort here typically adds to operational expense eg overtime pay. Ideally, the bottleneck is simply maintained at peak capacity.

In The Goal , Goldratt describes the 5-step process for continuous improvement:. Identify the bottleneck by seeing where you have the greatest upstream inventory piling up , with low inventory at the next step. Alternatively, see which downstream steps are most in demand of upstream parts and are idling. If you decrease inventory sizes, you will see which work center, if stopped, halts the whole line. Alternatively, in a more brute-force comprehensive way, define your market demand by sales , then compare the productivity of each step of the chain to this demand.

The protagonist of The Goal book undergoes multiple iterations of increasing capacity as his bottleneck to increase overall throughput. This is a good point to consider your own work or life in this context, and to construct effective ways to relieve your personal bottlenecks.

Again, take some time to consider how to apply these to your own life. Ideally, the flow through the bottleneck should match market demand.

Producing more than this will increase inventory of finished product. Instead, when you have surplus capacity, push to increase sales to make use of this capacity. This will decrease your overall cost per product. Once you identify the bottleneck and improve its capacity, you may find other problems arising that decrease throughput.

In The Goal , the team identifies a robot as the bottleneck. They devise a system whereby all parts destined for the bottleneck are always worked on at highest priority at non-bottleneck steps.

This increases throughput temporarily, until they discover that at final assembly, suddenly there are shortages in non-bottleneck parts while there is massive inventory upstream of the bottleneck. How could this be? They discover that they were running non-bottlenecks at full-speed, and having them crank out bottleneck parts far in excess of what the bottleneck could process.

In turn, the non-bottlenecks has insufficient capacity to produce their non-bottleneck parts. To avoid this, you must synchronize the non-bottlenecks with the bottleneck , to prevent massive deviations.

Goldratt proposed the Drum-Buffer-Rope method, as follows:. In addition, production requires prioritization — complicated chains require more parts to be worked on in the correct order to avoid queue times.

In The Goal , Goldratt suggests prioritizing batches by time elapsed since its release — the longer parts have been waiting, the higher the priority they get worked on. For parts going through bottlenecks, queue time is dominant.

For non-bottlenecks, wait time is dominant. Traditionally, larger batch sizes are seen as more efficient per part. However, larger batch size decreases agility and increases inventory. As discussed in The Goal , an hour saved at a non-bottleneck is a mirage. When you increase capacity at the bottleneck, you may start seeing shortages in non-bottleneck parts that hold up other parts of the chain.

For example, as in plot of the The Goal , a non-bottleneck may produce two parts — part Y that goes through a non-bottleneck chain, and part X that goes through a bottleneck. If you focus the non-bottleneck entirely on part X, then you create a scarcity of the non-bottleneck parts Y — which creates an artificial bottleneck. Similarly, taking on more orders may reduce spare capacity on non-bottlenecks, depleting inventory in front of the bottleneck and starving it of work. As the protagonist of The Goal book finds, productive practices can lead to virtuous cycles and increased competitiveness.

By adopting lean manufacturing principles like bottleneck alleviation, small batches, and Drum-Buffer-Rope systems:. In contrast, Goldratt points out how poor practices can lead to aggravating policies that cause further problems.

For example, obsessing on cost-accounting and local efficiencies:. But as you improve throughput, traditional accounting measures may make your situation look worse than in reality. However, these are usually temporary adjustments.

The survival of a company derives from its ability to generate value and profits and this is done when its products and services generate value for the consumer. Alex Rogo is the manager of a UniCo manufacturing plant. Its factory is running the risk of being closed by the UniCo directors. The factory is failing to deliver the products consumers want, and this brings permanent losses.

Production is lagging behind, employees are trying to catch up by working overtime, and everyone is tired and stressed out. Combined delays, worn out employees and overtime cost prevent the factory from generating money.

Without alternatives, Rogo seeks outside help. He hires a consultant named Jonah, to find improvement opportunities and save the factory. As the manufacturing and customer orders delivery is late, Jonah needs to reduce the time between the order made by a customer and the delivery of the product. To reduce this time, called lead time, from a few months to a few weeks, Jonah goes on to try to understand what may be stopping the factory from becoming profitable.

He realizes that although the factory is not generating money, it has teams that celebrate success by breaking their individual goals. Teams that had independent goals and were responsible for some steps in the process were succeeding. Because teams work together in the factory, a high-productivity team that hits the finish line at the right cost and ends up generating more inputs for other teams, which ended up stopping the manufacturing process.

That makes it clear to Rogo and Jonah that the high productivity of a team is not necessarily a good thing for the plant as a whole. The integration of the teams functions as a pipeline where a constant flow of activities occurs.

Products stand still in the middle of the process, the inventory grows unnecessarily, and resources invested by the company come to a standstill. However, the company was unable to deliver the products because many incomplete products would stand still after the first stage completion. Alex Rogo implemented a change by understanding the two types of resources.

If a team does a local performance optimization and this goal does not help the company achieve its goal, this is not a positive optimization. Together, Jonah, Alex, and his team set out to identify how to improve their production process. To reach the financial goal, they discovered that there are 3 tasks to be accomplished:. By acting on these 3 components, the factory could then reach profitability and the indicator to be tracked is net profit.

It is measured by the difference between earnings, defined as sales revenues less operating expenses and inventory costs. Another important indicator of being monitored is the return on investment.

The Goal Summary – Eliyahu M. Goldratt

It exists to measure the effort required to achieve a predefined profitability. To know your return on investment, you must divide the net profit by the inventory, that is, all the money that the company invests in the purchase of things that it intends to sell. Alex Rogo and Jonah then left to identify the company bottlenecks, the stages of the production line where the process stopped.

Once there are 2 teams causing bottlenecks, they impact the entire factory to produce at the slower bottleneck speed. Thus, employees would only work if it was possible to deliver the product to the customer at the factory speed. When work generates inputs that are not going to be used, what actually occurs is a waste and is not advantageous to the company. By optimizing the factory bottleneck processes, they realized that it was not necessary to focus on the processes that worked. Any effort in non-mitigating processes did not produce results.

Even the purchase of computers and robots to improve processes without bottlenecks was useless and a mere waste. With factory speed improving, the team can deliver products to the market in a timely manner.
