DRAWING THE LINE BETWEEN THEORY OF CONSTRAINTS AND SIX SIGMA
September 4th, 2011
The Theory of Constraints and the Six Sigma approaches are two of the most popular and most widely-accepted and practiced management paradigms. Some principles of the TOC run parallel to some of the basic tenets of Six Sigma. First, both paradigms believe that root causes of problems in the company or organization should be understood with a logical and rational approach. Second, both paradigms highlight the crucial role of top-line performance to the overall growth and progress of the company. Third, both paradigms uphold the value of the customers. Thus, the customer is indeed king. Last, both paradigms aim for stability in the performance of the system and clarity for improvement.
However, there are also several principles of each of the two paradigms that can be compared and contrasted with the other’s basic principles.
- 1. Focus. The Six Sigma method focuses on the smallest divisions and components of a company or organization. It focuses on the growth and development of smaller divisions. On the other hand, the Theory of Constraints focuses only on the most critical issues and on the entire organization. The Six Sigma believes that efficient smaller divisions will translate into a more efficient company. However, the TOC believes that a company made up of efficient and effective smaller departments may not even be effective and efficient as a group.
- 2. Method. Six Sigma uses a quantitative method and data-based philosophy in solving the company’s problems. TOC advocates a qualitative analysis and logic-based tools in dealing with critical issues.
- 3. Perception of Variation. Six Sigma aims to reduce variations and extraneous variables. TOC takes into considerations the individual differences and other potential variations. It will make the market healthier.
HOW THE THEORY OF CONSTRAINTS CAN BOOST YOUR BUSINESS
September 3rd, 2011
A holistic management philosophy popularized by Dr. Eliyahu Goldratt, the theory of constraints believes in the inherent simplicity of complex systems. According to this perspective, an organization may be made up of a lot of components and divisions but only a few or one factor can have a strong impact on the overall status of the organization. This factor, known as the constraint, serves as a hindrance to the group’s achievement of its goal.
The theory of constraints helps organizations and institutions to identify critical issues that hamper the organization’s growth. By identifying these critical points, organizations can take necessary steps and use these constraints to propel to greater heights. Thus, the theory translates impediments into profits and growth. These constraints include product quality, product cost, product engineering effectiveness, materials procurement, production planning and control and marketing.
The theory of constraints drives organizations to focus on the optimum efficiency of the organization. The optimum efficiency of the smaller units and divisions should come secondary. The theory of constraints operates using a five-step process. First, the organization needs to identify its constraints. Next, you need to think over and develop a plan on how you can exploit the identified constraints. Third, you need to place all the components of managing your organization subordinate to the constraints. Fourth, you need to place the identified constraints higher than everything else in terms of level of priority. Once you have broken the constraints, you should repeat the five-step process.
The theory of constraints also shares a couple of parallel or similar principles with other management philosophies. In TOC, continuous improvement is emphasized. Employees should be actively involved and empowered. Educating the entire organization is necessary. You have to transform and build a new organizational culture. TOC’s quality measurements are also clearly defined and established. By focusing on organizational goals over departmental goals, TOC helps eradicate barriers and divisiveness.

Increasing Efficiency with Simplicity
September 29th, 2010
Over-production is a type of waste. It has many different incarnations, but they all end up with a company spending money on something that generates no profit. Oftentimes, there are very small parts of your business flow that generate this waste and they can be tough to identify. In some cases, they may seem so small that their impact on your profitability is disproportionate, at first glance. Objective analysis of a business’s workflow, however, quite often reveals them to have very significant impacts. Read More »
What’s Constraining Your Company?
September 11th, 2010
The Theory of Constraints has to do with increasing efficiency at a company. Constraints are anything that prevents your company from working at its maximum level of efficiency. In order to bring this efficiency up to par with the modern business world, you have to first make an objective assessment of all of your processes and identify where those processes could be changed to make the workplace more efficient. This doesn’t mean being a brutal taskmaster with a stopwatch who looks for any and every flaw in their employee’s practices. In fact, it makes work more pleasant for everyone. Read More »
