DMAIC Cycle Used In The Six Sigma Process

While looking to enhance quality levels, a group of Motorola engineers designed a set of quality management tools that utilized statistical data as an approach toward the reduction of defects, and the improved maintenance of quality (Reddy & Hutton, 2013). Focusing on process improvement and variation reduction, Six Sigma uses a measurement-based strategy to improve quality, based on a systematic methodology known by its acronym - DMAIC (iSixSigma, 2012). Once problematic issues are recognized, the DMAIC model strives toward finding a long-term solution through the five phases of defining systems. By measuring key aspects of the current process for data collection, analyzing the collected data and verifying cause and effect relationships, improving current processes from data analysis, and controlling operations to prevent impact in any future process disruptions (Wallace & Webber,

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 focuses on defect prevention; improving quality, cost savings, and reducing waste by helping

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,

The basic principle of improvement by the processes of Six Sigma methodology is by the reduction of diffusion. The six sigma approach aims to reduce defect levels to only a few parts per million for an organization's key products and processes. The Six Sigma philosophy is based on the fact that all processes from design, through to manufacturing and to services provided to customers, display aberrances, which may result in product errors that cost time and money. These errors are variations of processes that can be reduced by various methods in order for the real cause of the problem to be systematically identified and

Six Sigma is a business metrics that seeks to identify and eliminate causes of errors or defects as well as failures in business processes by focusing on output that are critical to customers (De Feo, Barnard 2004). It is also a measure of quality that strives to eliminate defects using the application of statistical methods. In this case, a defect is defined as anything that could lead to customer dissatisfaction. Six Sigma’s statistical quality control is the method used to measure variability in a product for evaluation and corrective actions. When the product metrics exceeds the bounds of acceptability, based on statistical inference, the product can be rejected with reasonable assurance that does not meet requirement. It aims to identify and eliminate waste in order to increase speed and flow from start to finish. It also identifies the critical steps, and deleting those not required or nonessential. There are so many metrics process in today’s business industries but the metrics that Six Sigma’s statistical thinking can also be defined as a thought process. In which it recognize the variation is all around us and present in everything we do. The Six Sigma’s interconnected processes and identifying, characterizing, quantifying, controlling and reducing variation provide opportunities for improvement within any organizations or firms. That is to say,

Six Sigma is a quality improvement philosophy and a methodology and collection of statistical techniques used to implement that philosophy. Six Sigma’s focuses on reducing or removing identifiable sources of changes in order to decrease the number of defects in a product. Six Sigma was developed by Bill Smith and was used to standardize the way in which defects are tallied (Meredith, 2013). As a new way of doing business, six sigma can have a significant impact on the end result of business. There are many way six sigma can be applied. For example, the scientific component of methodology is a structure approach that takes

Six Sigma is a process improvement initiative developed by Motorola that assist organizations in identifying and reducing defects and inefficiencies within their existing business processes. The quality management system is a project-oriented system that drives cost savings and increases firm’s profitability by reducing variation in firm’s processes, products and services. (Russell, 2011). The process begins with four steps align, mobilize, accelerate and govern. Companies begin aligning by constructing company-wide metrics surrounding financial and strategic goals of the organization. These metrics are used to determine the area of the business that requires the most improvement and would have the largest financial

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,

In contrast to the just in time production process, the manufacturing flow chart of six sigma concentrates on DMAIC circle5. Unlike zero inventory in lean production, the process of six sigma production requires continuously diminishing the defect rate.

Six Sigma method is used to measure variation and defects in quality. Current competitive environment needs the qualitative product. Each feature of product including packaging should have quality to sustain in the market. So, the producers give consistent importance to quality control. The Six Sigma is very useful tool to find defects and its statistics. Six Sigma method has the goal of 3.4 defects per million parts. Six Sigma leads to world-class quality of the product. Six Sigma uses DMAIC tool and SIPOC for various analysis. Quality management program was firstly used by Motorola Inc. It describes quality measurement. Six Sigma is structured data driven method, which is using for quality improvement and eliminating waste.

Operational efficiency it 's significant across all levels of manufacturing goods. Making a profit is the fundamental principle for any business to succeed. Reducing overhead cost and eliminating waste are key factors in driving down cost and maximizing profits. The challenge lies in the ability to reduce product costs while simultaneously adding value, maintaining quality, and ensuring adequate availability of the production system. The idea of manufacturing goods in a systemic process comprised of balancing inputs and outputs across the value chain involve Just-in-time productions or systems. This production system incorporates a philosophical approach to integrated productions plans and

Many organizations use different methods to improves the performance, quality, and customer satisfaction to make the perfect products. Six Sigma is a one of the business process which used by statistical methods for removing defects in any process from manufacturing phase to deployment phase. Six Sigma approach was first proposed and developed by Motorola company in 1986. As it proved proven management strategy, which satisfies the customer needed all domains with a new technology. Six Sigma is a step by step project improvement approach where to select the project based on the organized strategy. It is a statistical tool and this process produce less than 3,4 errors per million opportunities. Six Sigma concept follows two procedures DMAIC (Define, Measure, Analyze, Improve, and Control) and DMADV (Define, Measure, Analyze, Design, and Verify) which are based on the Deming’s Plan-Do-Check-Act cycle.

There are mostly two types of variation in a process. A common cause variation is an uncontrollable variation that is bound to occur. Whereas special cause variation has a specific reason and occurs less frequently. These variations are caused due to 5Ms; Man, Material, Machine, Method or Measurement. These are unacceptable variations and can be developed or changed. There are six steps and two methodologies to implement a Six Sigma project in an organization. These are inspired by Deming’s Plan-Do-Check-Act cycle. The two methodologies are DMAIC and DMADV. DMAIC is used for projects aimed at refining an existing business process. DMADV is used for projects aimed at creating a completely new product or process designs.

This case study is about 6 sigma manufacturing process by which continuous improvement of the product is done. Mainly the 6 sigma is about improving the quality, In order to identify defects or errors. By using 6 sigma 99.9% the defect will not be there in the product. 6 sigma uses quality management and structural methods. The customer satisfaction can be increased by using this, production cycle can be reduced, reduction of waste and reducing the cost of the project.
