Metodología Six Sigma
Muchos nos hemos preguntado cómo funciona la metodología Six Sigma, o tal vez nos hemos preguntado cómo es posible que lleguen a ser tan pocos errores por tanta cantidad de producción, o será una tecnología como Six Sigma fácil de implementar… Para empezar es necesario conocer el significado de lo que es esta metodología, conocer cuáles son sus objetivos y metas y aprender porque es tan valiosa esta herramienta para nuestras industrias. En primer lugar la metodología Six Sigma, es una herramienta que se basa en conocimientos y procedimientos como el análisis para desarrollar mejoras y de esta forma evitar que se presente la variabilidad. Utiliza herramientas que le facilitan la obtención de datos así como herramientas estadísticas para la caracterización y el estudio de los procesos. Esta ideología fue iniciada en Japón, primariamente por la marca Motorola y es una evolución de otras herramientas que buscaban la mejora de la calidad de sus servicios. Si hablamos de los beneficios que esta metodología nos puede brindar son muchos, pero principalmente podemos decir que busca reducir o eliminar los defectos, fallas o errores en la entrega de un producto o servicio al cliente. Su principal meta de seis sigma es llegar a un máximo de 3,4 defectos por millón de sucesos, eventos u oportunidades (DPMO). Y uno de sus beneficios es que mejora la rentabilidad y la productividad. Para desarrollar esta metodología es necesaria la efectuación de varios pasos y todo el proceso de llegar a la meta final de los 3,4 defectos por millón podría tardar años e incluso podría ser una meta difícil de alcanzar. En resumen sus pasos son: definir el problema o el defecto, medir y recopilar datos, analizar los datos, mejorar y controlar el proceso. Luego sus resultados se clasifican dependiendo de su nivel de sigma, entre mas sigmas se posean menor es la ocurrencia de anomalías o defectos, se busca obtener el mayor numero de sigmas para llegar a un punto de perfección, o cero errores, estableciendo un clima ideal.
En conclusión, (Anthony y Anthony. 2009) los esfuerzos de esta metodología se enfocan directamente a mejorar lo que es verdaderamente importante para el cliente, incluso en productos conformados por varias dimensiones, Seis Sigma solo mejorará aquellas que puedan considerarse críticas para la calidad para no desperdiciar esfuerzos. Así como se mostro esta metodología trae grandes beneficios para las empresas ya por sus objetivos busca que los errores sean mínimos y que siempre exista un control estadístico sobre todo lo que ocurre para que de esta forma se pueda continuar controlando todo el proceso. * Definir el problema o el defecto * Medir y recopilar datos * Analizar datos * Mejorar * Controlar
Es una metodología de mejora de procesos, cuya función principal es la reducción de la variabilidad de los estos procesos.

...The methodology of Six Sigma can be traced all the way back to the eighteenth century in Industrial Europe. Carl Frederick Gauss introduced a conceptual normal curve metric which was later built on when Walther Stewhart showed how three deviations from the mean required some type of process solution. Finally in the late 1980s Six Sigma became closer to what we know it as today. A Motorola Engineer, Bill Smith, developed Six Sigma as a process for quality management. They came up with the idea or simply pointed out that the lesser number of mishaps at each stage of production would result in less defects. While this seems logical it had not been addressed before this point. At that time Six Sigma in its basic form was born, it included four stages; Measure, Analyze, Improve and Control. What is Six Sigma? Six Sigma is a methodology used by engineers and statisticians to limit the number of defects or errors in a process. However, today this method is being applied across all fields and it is no longer just for engineers and statisticians. Most people know the term as the process to achieve near-perfect results as far as customer requirements and efficiency are concerned. This is true because if a company truly achieves Six Sigma they have fewer than 3.4 defects per million potential defects or 99.997% precision. Motorola defines it as a “management drive, scientific methodology for product and process improvement which creates breakthroughs in financial performance and...

...Six Sigma Six sigma is a customer focused change strategy, used in business to help improve performance. It utilizes a systematic approach to improve the way people do process improvement. Six sigma helps businesses meet the two main goals of any business. That is to make money and satisfy customer needs. It also gives a business the ability to deliver accelerated results. Six sigma is a business enhancer that is embedded with tools and techniques that people can learn to improve their processes. There are two six sigma sub-methodologies. They are called DMAIC and DMADV. The DMAIC process of six sigma stands for: define, measure, analyze, improve, control. This process is an improvement system used for existing processes that fall below specification and need incremental improvement. This is also known as continuous improvement. With this process a business constantly seeks ways to improve. It has several benefits such as, an increase in customer loyalty, a reduction in customer dissatisfaction, and a reduction in opportunities for competition to get an edge in. This is routine action taken by workers to make minor improvements. This methodology is usually lead by workers close to the business and is only focuses on tasks in a specific area. The second sub-methodology of six sigma is DMADV. This stands for: define, measure, analyze, design, verify. This process is an improvement system used to develop new processes or products. This is also known as reengineering. It......

...Six Sigma and TQM/CQI Impact on U.S. Healthcare Regla Perez Keiser University Dr. Mary Granoff HSM691-G3 August 23, 2014 Introduction The concept of Six Sigma can be traced as far back as the late 1700’s when Carl Frederick Gauss introduced the normal curve. It wasn’t until the 1920’s when Walter Schewart was able to pinpoint the distance from the mean where a process which shows evidence of a defect or negative result, can be changed or corrected. However, it was Motorola’s Chairman Bob Galvin in the early 1980’s who after trying the traditional ways to measure defects realized they did not provide sufficient details that would identify the true effects of the defects within the manufacturer’s organization. It was at this at this time he introduced the concept of Six Sigma and helped the company’s bottom line which had not been a profitable one. Once the application of the Six Sigma concept became public, and the positive impact it had on Motorola’s bottom line, many other businesses wanted to learn about this concept. The impact of this concept was such that many of the executives of some of the largest companies have applied Six Sigma’s methodology to refocus their business on the road to profitability. What is Six Sigma? The concept of Six Sigma can be defined as an efficient methodology to problem solving which contributes to the improvement of performance of an organization or business. ......

...this essay I am going to critically analyse Six Sigma concepts in relation to contemporary software development projects. To do this I am going to research different topics of the Six Sigma focused on software development project. To begin with I am going to give an overview of the history of Six Sigma focusing on explaining aspects of its methodological development and give a detailed description of contemporary Six Sigma methodology. Finally I am going to analyse the central concepts of contemporary Six Sigma methodology and then conclude all of my work together and discuss the principal arguments. Six sigma is a methodology used to focus an organization on reducing variations and errors in processes and driving quality improvement. Developed by Motorola Inc in the USA in 1986, it became well known in the 90’s, when GE CEO Jack Welch evangelized it. Six sigma is now according to many business development and quality improvement experts, the most popular management methodology in history. Six sigma aims to maximise customer satisfaction and minimise defects. In statistical terms, the purpose of six sigma is to reduce the process variation so that virtually all the products or services provided meet exceeded customer expectations. The standard metric for Six Sigma is 3.4 defects per million opportunities. For example for every 1 million transactions that go through a system, there will be 3.4 errors and still achieve six sigmas. Therefore this process has so few defects......

...Six Sigma Six Sigma Introduction Six Sigma is a quality improvement method that is being used more frequently in healthcare. This tool was developed and used in industry since around 1980 and began to be used in healthcare in the 1990's (Powell, Rushmer, & Davies, 2009). According to Lighter (2011) "This lean process management system provides quality improvement professionals with the ability to remove non-value added work and improve process efficiency" (p. 287). The healthcare industry needs to find a way to get rid of errors. Today's society demands a lot from the healthcare providers and will not tolerate unnecessary errors, no matter how small they may seem. Six Sigma works to recognize errors as soon as they occur so they will be corrected before the error is carried out. If the process is fully reliable, appropriate healthcare will be delivered in the same way to all patients every time. If the care is evidence-based, then every patient receives optimal care regardless of who actually delivers the care, when it is delivered or where it is delivered (Powell, Rushmer, & Davies, 2009). Six Sigma uses the DMAIC (Define, Measure, Analyze, Improve, Control) approach. This approach first defines the problem, measures the defects, analyzes the cause of the defects, improves the process to remove the defects, and controls the process to ensure that the defects do not recur (Powell, Rushmer, & Davies, 2009). These steps need to take place to avoid......

...Six Sigma Desmond Studstill Keller University Six Sigma Six Sigma is a strategy that measures the degree that a business process deviates from its goal (Harry, 1998). Six Sigma is a rigorous and systematic methodology that uses information gathered from all company departments and statistical analysis to measure and improve operational performance, practices and systems of the organization by identifying and preventing defects in the manufacturing or service providing processes. Six Sigma provides a yield (return) on investment. Companies like General Electric have achieved profit growth of 2 billion U.S. dollars in 1999 in comparison to 1998 growth and profits of 2.4 billion U.S. dollars in 2000 compared to 1999. Statistical representation of Six Sigma approach describes quantitatively how a process works. To perform Six Sigma in the company means to achieve such progress in all parts of the process of creation or product / service, which means that the process and product are realized without any defects. To achieve Six Sigma, a process must produce less than 3.4 defects per million opportunities (DPMO). Six Sigma is focused on the client, the sigma improvement process is an important quality improvement standard as a five-stage model: Define, Measure, Analyze, Improve, Control, which is called the DMAIC process (Kwak & Anbari, 2006; Jones, Parast, & Adams, 2010). The main goal here is to allow the users to focus on applying the data to resolve the problems...

Design/methodology/approach – A specific research question is: does learning mechanisms and continuous improvement practices support each other and how, and what type of learning can be identified in the improvement of business processes. The question is linked to one of the fundamental issues currently discussed in the field of organizational learning; how do organizations get “from here to there”, in other words, what is the dynamics of the processes of learning and how progressive learning is achieved. A case study of a few Finnish companies is made and a procedural implementation model is applied. Findings – The findings suggest that the learning process is characterized by measurement, detection and correction of errors, and cost reduction.

...METODOLOGÍA SIX-SIGMA: CALIDAD INDUSTRIAL. 1 Ing. Gustavo López1 Investigador del Instituto de Ingeniería-UABC; glopez@iing.mxl.uabc.mx La elaboración de los productos en el área industrial involucra principalmente tres etapas: la entrada (personal, material, equipo, políticas, procedimientos, métodos y el medio ambiente), realización del producto o servicio (proceso) y la salida (brindar un servicio y/o elaboración de un producto). En dichas etapas se comenten errores que afectan la calidad del producto y/o servicio. Todos los días un defecto es creado durante un proceso (etapa), esto toma un tiempo adicional para la prueba, análisis y reparación. Estas actividades noadicionales requieren espacio, equipo, materiales y gente. Existen metodologías que ayudan a la prevención de errores en los procesos industriales, siendo una de ellas la Six-Sigma (6σ), que es una metodología de calidad de clase mundial (iniciada por Motorola en 19861 ) aplicada para ofrecer un mejor producto o servicio, más rápido y al costo más bajo. La Sigma (ơ) es una letra tomada del alfabeto griego utilizado en estadística como una medida de variación2. La metodología 6σ se basa en la curva de la distribución normal (para conocer el nivel de variación de cualquier actividad), que consiste en elaborar una serie de pasos para el control de calidad y optimización de procesos industriales. En los procesos industriales se presenta el costo de baja calidad, ocasionado por: a) Fallas internas, de los......

...The DMAIC is a core component of the Six Sigma methodology and is a structured problem solving process which provides all employees with a common language and a set of tools to communicate with each other, particularly as members of cross-functional teams, and is considered a roadmap for conducting a Six Sigma project. It is used when making improvements to an existing process. 1. Define – Define is the first step in the process. In this step, it is important to clearly define the problem. One must describe the problem in operational terms that facilitate further analysis. 2. Measure – The Measures stage (which is the most time-consuming part of the DMAIC methodology) focuses on how to measure the internal processes that affect CTQs. It requires an understanding of the casual relationships between process performance and customer value. 3. Analyze – Collecting data is simply not enough. The Analyze phase focuses on why defects, errors, or excessive variation occur. After potential variables are identified, experiments are conducted to verify them. Analysis reveals whether or not a problem is real or just a random event. 4. Improve – The improve stage focuses on idea generation, evaluation, and selection. Once the root cause of a problem is understood, the analyst or team needs to generate ideas for removing or resolving the problem and improve the performance measures and CTQs. 5. Control – The Control stage focuses on how to maintain the improvements, which......

...Six Sigma is a revolutionary business process geared toward dramatically reducing organizational inefficiencies that trans- lates into bottom-line profitability. It started in the 1980s at Motorola; then, organizations such as GE, Allied Signal, and Seagate worked with the initiative during the 1990s and made it the most successful business initiative of the era. Key to the Six Sigma methodology of the 1990s is a five- step process—Define, Measure, Analyze, Improve, and Control (DMAIC). By systematically applying these steps (with the appropriate tools), practitioners of this approach have been able to save substantial dollars. The basis of Six Sigma is measuring a process in terms of defects. The statistical concept of six sigma means our processes are working nearly perfectly, delivering only 3.4 defects per million opportunities (DPMO). Sigma (the Greek letter σ) is a statistical term that measures standard deviation. In the context of management, it’s used to measure defects in the outputs of a process and show how far the process deviates from perfection. A one-sigma process produces 691462.5 defects per million opportunities, which translates to a percentage of satisfactory outputs of only 30.854%. That’s obviously really poor perform- ance. If we have processes functioning at a three sigma level, this means we’re producing 66807.2 errors per million. Figure 1-1. DPMO at sigma levels nities, delivering 93.319% satisfactory......

...ways to exceed their expectations. This is why Six Sigma Quality has become a part of our culture. WHAT IS SIX SIGMA? Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service. A method that provides organizations tools to improve the capability of their business processes. This increase in performance and decrease in process variation lead to defect reduction and improvement in profits, employee morale, and quality of products or services. Six Sigma quality is a term generally used to indicate a process is well controlled (within process limits ±3s from the center line in a control chart, and requirements/tolerance limits ±6s from the center line). WHY SIX SIGMA? 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 Six Sigma defect is defined as anything outside of customer specifications. A Six Sigma opportunity is then the total quantity of chances for a defect. Process sigma can easily be calculated using a Six Sigma calculator. The fundamental objective of the Six Sigma methodology is the implementation of a......

...six sigma six sigma training, history, definitions - six sigma and quality management glossary Six Sigma is now according to many business development and quality improvement experts, the most popular management methodology in history. Six Sigma is certainly a very big industry in its own right, and Six Sigma is now an enormous 'brand' in the world of corporate development. Six Sigma began in 1986 as a statistically-based method to reduce variation in electronic manufacturing processes in Motorola Inc in the USA. Today, twenty-something years on, Six Sigma is used as an all-encompassing business performance methodology, all over the world, in organizations as diverse as local government departments, prisons, hospitals, the armed forces, banks, and multi-nationals corporations. While Six Sigma implementation continues apace in many of the world's largest corporations, many organizations and suppliers in the consulting and training communities have also seized on the Six Sigma concept, to package and provide all sorts of Six Sigma 'branded' training products and consultancy and services. Six Sigma has also spawned manay and various business books on the subject. Six Sigma, it might seem, is taking over the world. Interestingly while Six Sigma has become a very widely used 'generic' term, the name Six Sigma is actually a registered trademark of Motorola Inc., in the USA, who first pioneered Six Sigma methods in the 1980's. The original and technically correct spelling seems to......
