...THEORY OF CONSTRAINTS Key Term The key term I selected is Theory of Constraints. I selected this term because in my Aviation Maintenance profession this term is getting more visibility as we attempt to implement Continuous Process Improvement (CPI). Explanation of the Key Team Satterlee describes Theory of Constraints as the greater gain will come from identifying which part of the process is a constraint to the whole, rather than focusing on increased output from an entire process (p. 247). In support of the key term, I selected the article, “Theory of constraints: a theory for operations management” (Gupta & Boyd, 2008). Major Article Summary The selected article first investigates linkages between Theory of Constraints and the core concepts/components of operations management and shows how operations management concepts can be integrated with Theory of Constraints (Gupta, & Boyd, 2008). Next, the article proved Theory of Constraints has properties essential for a good theory. Within the article it identifies six steps for implementing the theory of constraints and also describes the five-step thinking process designed to organize the thought process involved in approaching a bottleneck and trying to resolve the problem relating to the constraint (Gupta, & Boyd, 2008). Discussion The Theory of Constraints is an important tool for operations managers to manage bottlenecks and improve process flows. Theory of Constraints views organizations as...

...Theory of Constraints The topic for my discussion on the Theory of Constraint is the team that handles rental properties for a real estate business. This includes homes as well as commercial properties for rent, from the perspective of the tenant and the landlord. The organization is a team of real estate agents that specialize in rental properties. The goal is to generate profitable revenue by ensuring the quota is met for lease contract agreements to go to settlement in the specified time. Throughput are the number of contracts for the lease of properties that have completed, settled, and funded. Inventory comprises of available rental properties that have been listed with the company, as well as landlords that are represented by agents of the company. Operating expenses include costs associated with the listing or showing of rental properties, such as open houses, advertising costs, and transportation of prospective tenants to the property. The bottleneck is the landlord’s approval and acceptance of the terms of the contract. This will be discussed in more detail in the five steps below. 1) Identify the system’s bottlenecks. Typically the landlord will want to maximize profit by listing the property for as much as possible. Regardless of the listing price being inline with the market area, or being overpriced, lease offers will often be less than the asking price. With lease offers from more than one prospective tenants require more time in their decision...

...Theory of Constraints In today’s economic climate, many organizations struggle with declining sales and increasing costs. Some choose to hunker down and weather the storm, hoping for better results in the future. However, layoffs and workforce reductions jeopardize future competitiveness. However, organizations that have implemented the Theory of Constraints (ToC) continue to thrive and grow in difficult times, continuing to achieve real bottom line growth, whether by improving productivity or increased revenues. Since 1985, the Theory of Constraints has been delivering startling tangible results to companies worldwide. An independent study of Theory of Constraints implementations around the world found that huge results were consistently achieved: Lead Times Reduced 69% Cycle Times Reduced 66% Due Date Performance Improved 60% Inventory Levels Reduced 50% Revenue / Throughput Increased 68% This is a system improvement tool, which states that every system has one goal and it is achieved by many linked processes and out of those processes, one process acts like a bottleneck. So, this theory is utilized in order to remove that bottleneck and ultimately achieve higher productivity. Commonly these bottle necks can be easily understood by the example of assembling operation. There are 5 stations; each station has different times for assembling e.g 40 minutes, 50 and 60 minutes. Out of these stations, station with maximum operation time will be considered as bottleneck...

Goldratt beginning around 1980 and later applied and augmented by a number of others. The Theory of Constraints has been applied to production planning, production control, project management, supply chain management, accounting and performance measurement, and other areas of business as well as such not-for-profit facilities as hospitals and military depots. It has also been applied to decision making in educational settings. Dr. Goldratt holds a Ph. D. in physics; he has often stated that in developing the Theory of Constraints he is applying the techniques of the hard sciences, such as cause-and-effect analysis, to soft sciences such as business management. The Theory of Constraints states that constraints determine the performance of a system. A constraint is anything that prevents a system from achieving a higher performance relative to its goal. A system is any collection of interconnected parts sharing a common goal. The Theory of Constraints was first applied to business systems. Dr. Goldratt defines the goal of a for-profit business as to make more money now and in the future. This definition is in keeping...

...The Theory of Constraints and the Automotive Industry The bottleneck appears in many aspects of the automotive industry. Not only is the specified branch of the manufacturer but also in more specific branches of products such as locally owned dealers, individual parts suppliers, and then on the consumer service side, repair shops. Looking at all of these some bottlenecks or constraints are easily identifiable. For this I will look closer at the service side of the industry and how the theory of constraints can affect the repair shops. First off forecasting for a repair shop can already be a hard to estimate because it is an as needed service. The slow-downs in this business are close to impossible to predict as there is no real season for car repairs. So the major constraint will be an unexpected demand in repairs. For the theory of Constraints to help with this, further causes for this restraint need to be identified. So if we are looking at a smaller locally owned shop we could identify the restraint as being poor scheduling of both labor and appointments. Once this is identified the theory will help ease the restraint. To handle this they will need to pad the forecast for the amount of work they estimate will be needed and accommodate the scheduling to match this. This can be done with a unique scheduling system for the shop with room for the varying service levels needed. With that the shop as a whole has to have the initiative to focus on the areas needed during...

...Introduction To apply the Theories of Constraints, we will need to express the goal and other measurements then outlining the five-step processes that will identify the bottleneck resources to dictate our throughput and inventory. Operational Measurements Our organizations’ operation will be expressed in three measurements; the goal, throughput, inventory and operational expenses. These measurements will help to keep our resources balanced and help increase the throughput while reducing the inventory and operational expenses at the same time. For the organization, the goal would be to obtain at least $15 million in funding sources within the next two fiscal years. We would pay special attention to the requirements of the competitive awards and would not attempt to complete proposals for awards that we are not currently eligible for. The throughput will be the number of grant proposals that are submitted. Our inventory is measured in open and eligible grants that we have not been completed or submitted. And the operational costs would include personnel costs, fundraising expenses and other resources that are used to complete the proposal process. The Five-Steps of the Theories of Constraints Step 1: Identify the organizational bottleneck(s). After reviewing the budgeted funding pipeline for the year, we only received 35% of the funding we expected between January and July. We found that there were grant proposals that we were eligible for that we did not compete for and...

... Theory of Constraints Theory of constraints (TOC) is about thinking in logical, systematic, or structured. It is about analyzing cause and effect, verifying basic assumptions, exploring alternatives and process improvement. The goal of TOC is to maximize the efficiency of a process selectively at the most critical points and thereby maximize profitability, quality, or other corporate objectives. The TOC has two major components. First, a philosophy that underpins the working principles of TOC. This is often referred to as TOC’s ‘logistics paradigm’ and consists of five steps for on-‐going improvement, the drum-‐buffer-‐rope (DBR) scheduling methodology, and the buffer management information system. This philosophy suggests that the main constraint in most organizations may not be physical, but in fact managerial-‐policy related. To address the policy constraints and...

...Theory of Constraints in Grocery Stores The Theory of Constraints (TOC) is defined as a management model that views any manageable process as being limited in achieving more of its goals by a small number of constraints. TOC is used to focus on identifying the constraint, rearrange the necessary policies and procedures and hopefully increasing the profits in the process. Most businesses can be seen as a series of associated sets of procedures that transforms contributions and productivity into a product that will ultimately result into a saleable profit. According to this theory, the goal for all successful business is to have a efficient system in place to make money more money then the company invested into it. Retail Grocery Stores: I worked in grocery/supermarket stores the majority of my professional career. I have watched supermarkets come and go but there were always a few chains that will always be around. I began to think about the chains that stand out from the rest and what made them successful. Most would say the success of a grocery store is selling quality products. I believe that is partly true. Customers also want excellent customer service that makes them feel special. Groceries stores sell products that every person needs to survive on a daily basis. Everyone needs to eat; everyone needs products for health, hygiene and wellness. The goal of a grocery store is to sell quality products before expiration and make a profit. When a grocery store is...

...Jorge Alonso Ruezga Luna Sistemas de producción II 01/12/2013 “Launching Krispy Natural: Cracking the product Management Code” Hi Marne good night. I´ve been analyzing our situation and our numbers and I think that we should review some points to ensure the well being of the strategy that we´re using. I think that the results of the potential of Krispy Natural were as expected, you were right. Natural Krispy received very good critics from our customers, even though our product has less crackers than the other brands. The roll-out strategy that we established should work just fine but due to our current situation I think that we will have to re-establish it. If Frito-Lay its going to enter the market we shouldn’t start with a roll-out nationally, we should focus on states, a strategy based on piece by piece program. Once we start to gain the confidence of our customers we start to grow in different areas. This will slow our forecasted demand and expansion but it should be a lot safer for us. Frito its not going to create a low class product since they are experts in selling salty chips, they ought to do some high class crackers, so we have to be careful on this. Our product its very tasty and we are having good responses for our customers so that why we should slow things up a bit so that we can start to penetrate the market, we have to focus on the idea that maybe our product has less crackers and its more expensive, but its worth it, and that’s what matters. I...

...where delivery of goods and services take place in there minimum through put time. One of the important approaches to achieve this goal is theory of constraints. Theory of constraint (TOC) advocates that existence of constraints in any systems gives opportunities for the management for improvement .Contrary to conventional thinking, theory of constraint view suggest constraint as a factor determining the performances that are positive to the system. Theory of constraint (TOC) seems to be feasible as it does not demand costly systems change. It depends on scheduling leased on constraint exit in the system.

...Overcoming Process Bottlenecks Jauwanna Pitts OPS/571 September 24, 2012 Michelle O'Hagan Overcoming Process Bottlenecks Bottleneck is defined as as any resource whose capacity is less than the demand placed upon it. A bottleneck is a constraint within the system that limits throughput (Chase, Jacobs, & Aquilano, 2006). In week one a flow chart was designed to measure and improve the process of International sales orders. The goal of the process flowchart was to create ways to make the order entry process less time consuming and more efficient. Action items were put in place to create a better process. An evaluation of the main bottleneck in the international order entry process will be reviewed. A definition and application of Goldratt’s theory of constraints to identify and overcome process bottlenecks will be included as well. The Process The main bottleneck in the international process is the fact that entering orders is such a manual process. There are twelve steps involved to enter one purchase order: 1. Receive orders by email 2. Flag orders according to importance 3. Print emails 4. Move orders to the individual countries folders in Microsoft Outlook 5. Correlate the orders 6. Staple the orders 7. Separate the orders by country for order entry 8. Pull up electronic copy of the international address book 9. Order Entry 10. Sent order acknowledgement to sales office to confirm accuracy before placing order in the production schedule. 11. Once...

...consistency bases to improve my time. I will go over the bottleneck in my process and also reflect on how I can am able to apply The Goldratt’s theory of constraints in order to identify and finally overcome the bottleneck in my routine. Process Bottleneck Being able to the bottleneck can become a very important aspect of the analyzing the process because it allows for capacity to be identified in the process as well as the opportunity to increase it. Looking at the flowchart and the metric system I determined there was a few things aside from time that became my bottleneck such as over sleeping by hitting the snooze button and if I had my clothes for the day ready. A result of these two either gave me more time in the morning or delayed me to have a crunch on time. It seems that these are my two major problems in the morning everything is else is simple and flows quickly as the time permits it and allow me to rush to work on time or have time to be calm arriving to work accomplishing the goal of getting to work on time. Based on this we can see that once getting through the first two steps then the rest is faster to accomplish. At this point it is past my bottleneck that in turn this would out me that increasing the amount of the bottleneck then it will have a limited influence on the capacity of the process. Goldratt’s Theory...

...Bottlenecks in a Process University of Phoenix OPS/571 Operations Management November 12, 2012 Bottlenecks in a Process High process performance is often the main focus for any organization. Therefore, individuals continually search for ways to improve their processes and increase their efficiency. Those wishing to improve the efficiencies of these processes must identify and eliminate the activities that prevent the process from moving at a steady pace. The purpose of this paper is to briefly discuss the process of maintaining a timely bedtime. This paper will identify and discuss the main bottlenecks within the process. This paper will also apply Goldratt’s theory of constraints to help identify and overcome the process’ bottlenecks. The Process As identified in week one, the author wanted to find a way to achieve and maintain a timely bedtime on weekdays. The author created a flowchart to identify the activities within the process and collected data indicating the time spent performing those activities. Traveling home from work, preparing dinner, helping her daughter with homework, and cleaning the kitchen are among those activities. Other activities were participating in social networking and preparing for the next work day. Several factors affected these activities such as the travel method, the time spent on social network, and the need to defrost meat products for dinner. These factors, if...
