Resumen

¿Qué es el Six Sigma? Explicación

Six Sigma es una metodología de la gerencia de calidad que provee a las empresas de herramientas para mejorar la capacidad de sus procesos de negocio. Este aumento en el desempeño y la disminución de la variación de los procesos conducen a la reducción de defectos y a la mejora de los beneficios, de la moral del empleado y de la calidad del producto. Es una medición de la calidad y un programa de mejoramiento que fue iniciado por Mikel Harry y Motorola. Se centra en el control de un proceso para llevarlo desde su linea de partida hasta el punto Six Sigma (desviaciones del estándar) es decir, a un nivel de 3.4 defectos por millón de productos producidos. Incluye la identificación de los factores que son críticos para la calidad según lo determinado por el cliente. Reduce la variación del proceso y aumenta las capacidades de mejomiento, de estabilidad y de diseño de sistemas para apoyar la meta del six sigma.



Six Sigma 6 ΣEl modelo Six Sigma es un acercamiento altamente disciplinado que puede ayudar a las compañías a centrarse en desarrollar y entregar productos y servicios casi perfectos. Se basa en el trabajo estadístico de José Juran, nacido en Rumanía, pionero en los E.E.U.U. de la gerencia de calidad. La palabra “sigma” es un signo griego usado como un término estadístico que indica, hasta que punto las medidas de un proceso en particular, se desvían de la perfección (desviación de estándares). Mientras mas alto sea el número sigma, usted estará más cerca a la perfección. Un sigma 1 no es muy bueno; sigma 6 se define como 3.4 defectos por millón. La idea central detrás Six Sigma es que si usted puede medir cuántos “le deserta” tenga en un proceso, usted puede calcular sistemáticamente hacia fuera cómo usted puede eliminarlos. Así usted puede casi venir “poner a cero defectos”.

El origen japonés del Six Sigma se puede observar por el sistema de “cinturones” que utiliza. Si usted es nuevo en el Six Sigma estará en un entrenamiento básico, por tanto, usted consigue un cinturón verde. Cualquier persona que tiene la responsabilidad de conducir un equipo Six Sigma usa un cinturón negro. Finalmente hay un grupo especial de élite llamado Maestros de cinturón negro que supervisan a los cinturones negro.


Cinco pasos hacia el Six Sigma. Proceso

Típicamente, Six Sigma es un proceso que tiene las cinco etapas siguientes:

  1. Definición. El primer paso en un proyecto Six Sigma es clarificar el problema y definir su alcance de una manera tal que se puedan alcanzar las metas cuantificables dentro de algunos pocos meses. Entonces se convoca un equipo para examinar el proceso detalladamente, para sugerir mejorías, y para poner esas recomendaciones en ejecución. En el mundo de la fabricación, los encargados de proyecto y sus patrocinadores típicamente comienzan definiendo qué es un defecto y después establecen un sistema de objetivos diseñados para reducir la ocurrencia de tales defectos.
  2. Medición. En el segundo paso de un proyecto Six Sigma, el equipo recopila datos y los prepara para un análisis de alto nivel.
  3. Análisis. Una vez que se ha mapeado y documentado un proceso, y se ha verificado la calidad de los datos de apoyo, el equipo Six Sigma puede comenzar el análisis. Los miembros del equipo comienzan identificando las maneras en las cuales la gente falla en actuar como se es requerido, o identificando los motivos por los cuales la gente no puede asegurar el control eficaz de cada etapa.
  4. Mejoramiento. Recomienda, decide y pone en ejecución las mejorías.
  5. Control. En la etapa final de un proyecto Six Sigma, el equipo crea controles. Éstos permitirán a la compañía sostener y ampliar las mejoras.
