The theory of constraints (TOC) focuses on using organizational change techniques in order to increase company profits. Goldratt (1984) introduced the theory of constraints in a business novel titled, The Goal. The TOC states that all companies have one constraint that prohibits them from reaching strategic goals or objectives (Aryanezhad, Badri, & Rashidi-Komijan 2010; Gupta, & Boyd, 2011).
The TOC was derived from optimized production technology (Fry, Cox, & Blackstone, 1992). In 1990, the basic principles of the theory of constraints were established (Ronen & Starr, 1990). Practical use of TOC was applied to human resource management and supply chain management in the late 1990s (Blackstone, 2001; Horng-Huei et al., 2013). The foundational theory was broken down in to 3Ms in 2004 (Boyd & Gupa, 2004); and finally by 2008 TOC was being used globally in various operation and project management environments (Gupa & Boyd, 2008).
Project managers do not always need lean management techniques or Six Sigma to solve problems. One of the commonly used techniques to solve problems within project management is by applying the theory of constraints, a term that was coined by Goldratt (1984). Goldbratt (1984) stated that in any business there are constraints or bottlenecks that prevents the business from flourishing and can impede the progress of the business. For example, if one team is capable of making a 10 cars per day while another team is capable of only making two, there should be an examination to determine what is impeding the other team from making 10 cars. From a business perspective, a project manager should want to find ways to eliminate the constraints. Goldratt (1984) stated that the Theory of Constraints could be...

The Goal is a book that focuses on the theory of constraints in order to improve production. Eliyahu Goldratt brings us a pleasant story that shows the important strategies that any manager or CEO should follow to be successfully productive, and capable of reaching their goals. The book easily explains and demonstrates many attainable ways for any human being to learn how to manage their industrial relations, business processes, and also, their personal lives.

Theory of constraints (TOC) is a systematic management approach that focuses on actively managing those constraints that impede a firm’s progress towards its goal of maximizing profits and effectively using its resources. (Krajewski, Ritzman, & Malhotra, 2013). It outlines the deliberate process for identifying and overcoming constraints. The process focuses on the efficiency of individual processes and bottlenecks constraining the overall system. According to Krajewski, Ritzman, & Malhotra, the TOC methods increase the firm’s profits more effectively by focusing on making materials flow rapidly through the entire system. Therefore, the constraints are the weak link. The performance of the entire chain is limited by the strength of the weakest link in manufacturing processes. TOC focuses on the process that slows the speed of product through the system.
TOC was initially a manufacturing method, but evolved and developed into a theory about management in many forums and arenas of business. The TOC philosophy applies to any organization that has a constraint and has been useful in discovering either one constraint or many small constraints that can plague and dominate an entire system. The secret of the TOC’s success lies within managing the constraints that are found in the process or subsystem while managing the entire process to gain the most benefit out of the complete system. Drum-Buffer-Rope scheduling theory, another of Goldratt’s scheduling techniques, is a metaphor to understand the flow of a supply chain by increasing throughput by adjusting buffers by utilizing a rope and controlling the speed of the supply chain by a drum. The metaphor for the Drum-Buffer-Rope could find application with the TOC, where adjustments need to be made anywhere along the process where functions happen too soon or not soon enough in order to keep the process moving at the same pace throughout. Utilization of this theory and identifying the constraints with the TOC are among some of the general principles espoused in Goldratt’s book, The Goal, which has proven useful for successful manufacturing and process management (Balderstone & Mabin,
The projects in today’s world are given a lot of importance and it will continue to grow in the coming years. There are a lot of companies which do not have production, but all of them do have projects. There are a lot of books which have been published on which related to planning and managing the projects. The one of the most important one was published by the author Eli Goldratt in his book ‘Critical chain’. This book basically talks and shows how the application of theory of constraints in the field of project management. The novel is basically based on one of the MBA classes in America where a number of ideas are developed in discussions among the students and the lecturers. The lecturer is basically fighting for a tenure with the president of the university who expects a downturn in the executive MBA. The lecturer who teaches project management has a word with one the senior colleagues and project management was the right topic to teach. There were three students who were placed in the project management team of their company which manufactures electronic products. The students are enrolled in this MBA class along with other students, here they discover a new approach to project management which is known as the
Project management is a discipline based on careful planning, organization, motivation and control of resources to achieve specific goals and meet specific success criteria. Since every project is unique in nature, a project manager must learn to adapt and identify key areas to drive success. Thus, as a learning initiative, we were given a project to manage through a simulation program named Sim4Project. The emphasis of this simulation was on learning-by-doing, just like in a real-life project. Sim4Project provided a good mix of theoretical knowledge as well as hands-on experience. Professor Leonie gave feedbacks at the end of each period to ensure we were incorporating the project management principles learned in the classroom.
The theory of constraints or TOC help organizations deal with its limits to achieve its selected goals throughout the year. Underneath shows the five steps of the theory of constraints and how Nissan could use each one. The first step is to identify the constraint, which Nissan could utilize in order to identify
Project management is said to be completed within time when it completed within the “triple constraints”: cost, time and quality. And in a lot of causes, one them is sacrificed so as to meet the other two. Project managers prioritize which ones are the most important.

In the introduction of the book of Norman Long, “Battlefields of Knowledge”, Long states that theoretical and the application itself cannot be segregated into their respective venues. His book takes a different perspective specifically by not discriminating between the “knowledge of understanding” and “knowledge of action.” Long’s book assumes that the theoretical and the pragmatic issues are so intimately entwined that it would be like separating melted ice from your coke. Long stresses that we must work on an actor-oriented approach where we can base new types of theorization and methodologies.
Project management involves all activities that encompass scheduling, planning, and controlling projects. A successful project manager ensure that an organization’s resources are being used both efficiently and effectively. Most projects need to be uniquely developed require a sense of customization and the ability to adapt to any posed challenges. The scope of effective project management includes defining what the project is and what is being expected to be accomplished. Projects are imposed to fulfill a certain need and project managers must have the ability to create the proper definition. Goals and the means used to attain those goals have to be clearly stated. Project Managers must also have the ability to plan
