The Dmaic Framework : The Six Sigma Essay

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,

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.

The driving factors for a success or failure of implementing Six Sigma is largely dependent on the inputs set forth at the conception and duration of the integration. This whitepaper will compare and contrast these critical inputs for a successful deployment. In order to accomplish this five various companies: GE Electric, W.R. Grace, Royal Chemicals, Diversified Paper and Lemforder. Some of these organizations had very successful results while others failed to reach their full potential. What is clear is the similarities of those that succeed and those that failed.

Committed leadership of top management and fully fledged training are crucial to the success of Six Sigma implementation. Human resource functions need good harmonization with Six Sigma approach(Tjahjono, B. et al., 2010).The right selection and prioritization of projects is also a critical success factor(Antony, J., 2004).

DMAIC (Define, Measure, Analyse, Improve, Control) is a sub-methodology helps improvement of the existing processes. It is often necessary to iterate through the Measure-Analyze-Improve steps.

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

When the venture is comprehended and the standard execution reported and checked that there is genuine open door, it is time with the six sigma way to deal with do an investigation of the procedure. In this stride, the six sigma approach applies factual devices to approve main drivers of issues. Any number of devices and tests can be utilized. The goal is to comprehend the procedure at a level adequate to have the capacity to figure choices for development. We ought to have the capacity to contrast the different choices and one another to focus the most encouraging choices. Likewise with numerous exercises, equalization must be accomplished. Shallow investigation and comprehension will prompt useless choices being chosen, compelling reuse through the procedure to make enhancements. At the other amazing is the loss of motion of examination. Striking the proper parity is the thing that makes the six sigma Black Belt very significant.

Six Sigma is a measurement based strategy for process improvement and problem reduction. It is completed through the application of the Quality Improvement project and accomplished with the use of two Six Sigma models. One model is DMAIC (define, measure, analyze, improve, control), which is designed to examine

The Six Sigma methodology can be described as a management philosophy that focuses on developing and delivering near perfect products services. The approach uses the DMAIC structure and a set of improvement tools to identity causes of variation and to develop improvement strategies that reduce opportunities for defects and variation in process (Galli & Handley, 2014). DMAIC is the acronym for Define, Measure, Analyze, Improve and Control. The central idea behind Six Sigma is that if the defects of a process can be measured, then solutions

First, The Six Sigma, usually intended as a professional plan, includes refining, scheming, and monitoring procedure to minimalize or remove excess while enhancing gratification and increasing financial steadiness. The performance of a procedure—or the process competence—is used to ration enhancement by associating the baseline process competence (before development) with the process competence after directing possible solutions for quality development.

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,

Six Sigma main purposes were to enhance performance and value. The use of Six Sigma in organization can upgrade communication among employees, customers, and shareholders. An organization which applies Six Sigma within their establishment is taking on a commitment to motivate and instruct their employees on the various principles. In essence, the Six Sigma is has become a way that companies can protect themselves from accountability. “ If a company produces a product that is low in quality or can harm its user, the organization can use the defense that quality is at the forefront in order to be viewed positively” (http://www.tech-faq.com/).

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.

Definition of Six SigmaSix Sigma is not a mere methodology or a quality tool. It is a philosophy i.e. a systematic way of thinking to solve quality problems. Six sigma involves

Six Sigma has two different focuses which includes Management and technical [1]. The Management focus deals with Project metrics, identifying goals, approving/selecting projects and selecting the workforce on the project [1]. The technical focus primarily deals with minimizing the variation and improving process performance. Six Sigma predominantly depends on the management team inorder to complete the assigned projects in timely manner and to ascertain meeting specific objectives. The Business improvement involves five different stages. Define, Measure, Analyze, Improve and Control. Six Sigma gives at most importance to detailed results at the bottomline and predict the impact on the Business environment before the Project is approved. The four significant aspects of Six Sigma are customer satisfaction, understanding of the Process, critical decision – making and Business results. Six Sigma is advantageous for companies that rely on bottom-line results and minimizing the number of defects in the Production process. Six Sigma serves as the common technique or mode in order to measure quality gains of different organizations and also to compare one
