* Article Question: According to the author’s standpoint, describe what are the differences between theory/application/focus factors when comparing six sigma, lean and theory of constraints. Please elaborate your answer without writing article sentences, use you own words and demonstrate a comprehensive analysis.
Making a comparison with a simple standpoint, the six sigma’s methodology is used to incremental improvement of existing processes, as it is the six sigma main tool, DMAIC. This tool is a strategy based on statistical quality, which gives much importance to data collection and accuracy of the data as a basis for improvement.
Each step in the methodology focuses on obtaining the best results possible to minimize

* What factors are critical when choosing the right improvement strategy?
There three factors that must be evaluated in two different focuses to choose the right improvement strategy. First, identify the need of your organization in terms of relationship between the primary theory and the primary focus of the tools and methodology. Dave Nave calls it “the first effect or primary effect” in which the organization understands what are the tangible results want it for their company, such as: * Six sigma, if we focus on reducing variation, then we will have more uniform process output. * Lean, if we focus on waste removal, then flow time improve. * TOC, if the focus on constraints, then throughput volume will improve.
Second factor; identify the secondary effect in which it can be described by using a theory and primary effect results.
* Six sigma, focus on reducing variation and achieving uniform process results in less waste, less throughput time and less inventory. * Lean, focus on waste and flow time results in less variation, uniform output and less inventory. * TOC, focus on constraints and increased throughput results in less inventory and different accounting system.
Third factor, the selection of a process improvement methodology according to the organization’s culture. Here are some
Lean Six Sigma concepts were introduced in the book titled Leaning into Six Sigma: The Path to Integration of Lean Enterprise and Six Sigma (Lean Six Sigma). Lean Six Sigma methodologies combine lean manufacturing and Six Sigma strategies to rely on improved performance from a collective team effort that systematically reduces variation and removes seven kinds of waste, known as Muda. Muda includes any unnecessary motion, transport, wait time, inappropriate processing, excess inventory, overproduction, and defects (Lean Six Sigma). Furthermore, Lean Six Sigma methods aim to provide customers with the best possible quality, cost, and delivery (ASQ.org, n.d.). In all, Lean Six Sigma is a business performance improvement strategy that uses a systematic approach to improving the way people advance processes. Its methodologies allow for systematically enriched processes to satisfy the customer and make money. Simply put, Lean Six Sigma as a business enhancer, ingrained with tools and techniques people can use to learn how to improve their processes (iSixSigma,
1. Six Sigma is a management philosophy that sets objectives, collects data and analyzes results as a way to remove wasted expenses from its processes and help reduce the number of defective products produced. Six Sigma uses quality measures to strive for near perfection by eliminating errors and variables.
Six Sigma is a business instrument for the betterment of a process. It is a controlled approach and methodology for obviating defects in any process such as manufacturing, businesses and any product or service. Six Sigma has been gaining tremendous popularity in industry today. However, academics have conducted limited research on this rising phenomenon. Interpreting Six Sigma primarily requires giving out a conceptual definition and describing an underlying theory. This topic uses Grounded theory approach and meager literature available to suggest an initial definition and theory of Six Sigma. This paper indicates that although tools and techniques on the topic are similar to earlier approaches of quality management, it provides a structure which is more detailed. This emerging structure for quality management attempts to improve the quality of the yield of a process by identifying and obviating the defects and causes lowering variability in business processes. Also one of the important areas touched upon is the conceptual understanding of Six Sigma. Each Six Sigma project executed inside an
Lean Six Sigma combines Lean’s time-focused waste-elimination philosophy to dynamic analytical problem solving toolkit of Six Sigma.
There are always pros and cons to any quality improvement methodology. For instance, the pros of Six Sigma tend to place extreme importance on leadership and its support for the success of the project. Another pro is the integration of different human elements, which include cultural change, and focus on the customer and their needs. “By using the concept of statistical thinking, Six Sigma encourages applications of statistical tools and techniques that reduce variability” (Harry, 2000). The cons of Six Sigma include, not having the quality data available, especially when a new process has been implemented without having the data available. Often the solutions that Six Sigma proposes can be costly and only a small
Six Sigma is the business strategy and a philosophy of one working smarter not harder.
Six Sigma focuses on defect prevention; improving quality, cost savings, and reducing waste by helping
The lean philosophy centers on the elimination of waste in all forms in an organisation (Shpak, 2016). Lean is usually implemented by initially
Lean Six Sigma is a combination of two business-improvement systems, Lean and Six Sigma. Lean refers to the reduction of waste, or the elimination of unnecessary steps to increase speed and productivity. Six Sigma is the reduction of variance to improve system performance. Ultimately, the depot’s bottom line is a process that frequently produces a high-quality product, on time and within or below established budgets, so that equipment can be returned to the Warfighter quickly and at the lowest possible cost to the taxpayer.
Lean management requires a value stream to define all activities, both value-added and non-value added, in order to deliver a specific service. By conducting a value stream analysis, you can identify waste and create a definite plan of action to eliminate that waste and improve your service process.
The Lean Six Sigma looks for ways on how to eliminate defects. In healthcare, a defect can be the difference between life and death. The Lean Six Sigma is used to improve patient safety by eliminating life-threatening errors. Lean Six Sigma uses a five-step approach to process improvement called the Define-Measure-Analyze-Improve-Control (DMAIC). The DMAIC is an approach that is a data-driven quality strategy used to improve processes (ASQ, n.d.). The first phase, the define phase, is where the leaders would define the problem and begin to understand the needs of the customers. This is an important phase of the Lean Six Sigma because this is where the team would outline of their efforts for themselves and the leaders of the organization (goLEANSIXSIGMA.com,
Six Sigma is a set of tools, processes and techniques that aid in the improvement of any
The concept of Six Sigma was developed in the early 1980’s at Motorola Corporation (Harry and Schroeder, 2000). Six Sigma can be defined as a statistical measure of the performance of a process or product (Kumi et. al., 2006). It is used as a quality control mechanism, which seeks to reduce defects or variations in a process to 3.4 per million opportunities thereby optimizing output and increasing customer satisfaction (Sambhe, 2012). Sigma is representing the standard deviation, a unit of measurement that designates the distribution or spread about the mean of a process (Six Sigma Academy, 2002). In addition, the Six Sigma uniquely driven by close understanding of customer needs, disciplined use of fact, data, and statistical analysis, and diligent attention to managing improving, and reinventing business processes (Pande, P., et. al. 2000). The Six Sigma methodology uses statistical tools to identify the factors that matter most for improving the quality of processes and generating bottom-line results. The Six Sigma DMAIC (Define, Measure,
The establishment of Lean Six Sigma is to take a gander at items/benefits through the client 's eyes and decide how enhancements can wipe out "waste". Lean Six Sigma takes after a thorough methodology of DEFINE… MEASURE… ANALYZE… IMPROVE… CONTROL. Through this procedure we distinguish the 7 sorts of waste that is, Overproduction, Inventory, Extra Processing, Motion, Defects, Holding up, and Transportation. A group is structured to direct an Action Work Out to actualize changes that will wipe out the waste. Since "Waste makes Waste" we should ceaselessly Kaizen (improve) to streamline and streamline our methodologies. We exceed expectations to model the Toyota Production System (TPS) with the aid of Shingijutsu specialists that show us the
Looking at the success of Motorola, many companies like Texas Instruments, Allied Signal etc started using Six Sigma methodology to bring organization-wide improvements.
