Six Sigma: Overview

Successful deployment of Lean Six Sigma is often considered a function of the inputs with those being shown below in figure 1.1. As the companies are evaluated keep in mind those critical X’s are often evaluated as the function Y = f(X) or Outputs = f(Inputs). In other words by controlling the inputs an organization can predict the output of the Lean Six Sigma implementation. This point is key when evaluating the difference between successful and not-so-successful implementations.

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

One of such strategy is the implementation of Six Sigma methodology in the organization. Six Sigma is a methodology that combines the gradual and continuous improvement with radical redesign. The process of Six Sigma begins by measuring the statistical variability within a process. This means that the causes of error can only be determined if you understand the critical requirement of either the internal or external customer. Six Sigma processes are designed to reduce process variability. Six Sigma helps the organization to achieve improved process flows and better

Continuous efforts to achieve stable and predictable process results (i.e., reduce process variation) are of vital importance to business success.

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 attempt to identify and remove the causes of defects and errors in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and develops a special infrastructure of people within the organization ("Black Belts" etc.) who are experts in these methods (Harry, 1998). Project of Six Sigma project follows a pre - defined sequence of steps and has project

Six Sigma means a measure of quality that strives for near perfection. Six Sigma is a disciplined and data-driven approach or methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process , from manufacturing to transactional and from product to service. The statistical representation of Six Sigma describes quantitatively how a process is performing. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A defect is defined as any process output that does not meet customer specifications. The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation

DMAIC is a process that can be used to identify and measure the overall performance of Lean six sigma. It consists of the process to be followed when applying lean six sigma. Define: a problem that needs solving is first identified. Everyone involved should be able to know their role, one should know what the projects aim is and what should be achieved at the end of it. Measure: The work that is done in the above stage is founded on what the problem is thought to be. During this stage things should be clarified by viewing how well work gets done. Analyze: this follows after knowledge of what’s happening is acquired. Manage by detail to check out the likely causes and know the root cause.

This paper explores eight published books about Six Sigma and Total Quality Management. This paper will compare, contrast, analyze, discover, balance and provide excellent understanding of both quality methods.

Process improvement is a fundamental to business management.  If you run an operation (and all businesses do, one way or another) you are reliant on two things:

Six Sigma is a business administration methodology initially created by Motorola, USA in 1981. Starting 2010, it appreciates far reaching application in numerous parts of industry, in spite of the fact that its application is not without discussion.
