Six Sigma and ISO

Six SigmaSix Sigmais a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorolain 1986Six Sigma seeks to improve the quality of the output of a process by identifying and removing the causes of defects and minimizingvariabilityinmanufacturingandbusiness processes. It uses a set ofquality managementmethodA six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defective features per million opportunities). Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a by-word for the management and engineering practices used to achieve it.

Steps for implementation for Six SigmaStep 1 : Define the priorities of customer with respect the qualityProduct that are considered most important by the customers in evaluating the quality of product are identifies.These attributes are called critical to quality.The customers perceptions of quality attributes is updated from time to time by conducting customer survey. Step 2 : Measure the processes and the defects arising in product due to the processThe important processes influencing CTQ are identified and performance measurement techniques are established for these processes. The processes are measured and defects arising in the product due to prcoesses are identified.

Step 3 : Analyze the process to determine the most likely causes of defects.The key variable most likely to be responsible for variation in the process are identified to find the reason for defect generation. Step 4 : Improve the process performance and remove the cause of the defects.Specification limits of key variable are fixed and system for measuring the deviations of variables is established and validated. Steps 5: Ensure the improvements are maintained over timeThe modified process is subjected total regular interval of time to ensure that key variable do not show any unacceptable variation.

ISO (International Organization for Standardization)TheInternational Organization for Standardization(ISO) is aninternational standard-setting body composed of representatives from various nationthe organization promotes worldwide proprietary, industrial and commercial standards. It is headquartered inGeneva, Switzerlandastandards organizations.ISO, the International Organization for Standardization, is an independent, non-governmental organization, the members of which are the standards organization of the 164 member countries.

ISO 9000TheISO 9000family ofquality management systemsstandards is designed to help organizations ensure that they meet the needs of customers and other stakeholders while meeting statutory and regulatory requirements related to a product.ISO9000 deals with the fundamentals of quality management systems,ISO 9001 deals with the requirements that organizations wishing to meet the standard must fulfill.

Evolution of ISO 9000 standardsThe ISO 9000 standard is continually being revised by standing technical committees and advisory groups, who receive feedback from those professionals who are implementing the standard. ISO 9001:Model for quality assurance in design, development, production, installation, and servicingwas for companies and organizations whose activities included the creation of new products.ISO 9002: Model for quality assurance in production, installation, and servicinghad basically the same material as ISO 9001 but without covering the creation of new products.ISO 9003: Model for quality assurance in final inspection and testcovered only the final inspection of finished product, with no concern for how the product was produced.

Two documents are provided by ISO as guidance to organization for understanding various aspects of good quality systemISO 9000 : This document explains principle concept and applications for understanding various quality systemISO 9004 : This document explain principle concept and application guide to quality management and quality system elements.

ISO 14000ISO 14000is a family of standards related toenvironmental managementthat exists to help organizations (a) minimize how their operations (processes, etc.) negatively affect the environmentThe standard's first requirement is that your company have a publicly available environmental policy articulated by top management. It should be appropriate to the nature of the organization and include commitments toward pollution preventionEach employee's role and position must be clearly defined, and all employees must be aware of the impact of their work on the environment. Your company is responsible for ensuring that all employees are adequately trained.

The ISO 14000 standards aim at giving companies direction for managing, measuring, improving and communicating the environmental aspects of their operations. Experts predict that the standards will influence the design and manufacture of products, selection of raw materials, marketing, the type of environmental data gathered and the means by which data are exchanged internally and externally.Organizations must continually monitor and document their environmental effects and periodically review them to ensure continual improvement and the effectiveness

Assignments What is Six Sigma? Write steps for implementing six sigmaWhat do you mean by six-sigma? Explain various analytical tools associated with six-sigma.What is Six Sigma?
