Solution

Para responder a esta pregunta, sigamos los siguientes pasos:

  1. Entender el concepto: La pregunta se refiere al principio de Pareto, también conocido como la regla 80/20. Este principio sugiere que el 80% de los problemas pueden ser atribuidos al 20% de las causas.

  2. Analizar las opciones:

    • FMEA (Failure Mode and Effects Analysis): Es una herramienta utilizada para identificar y evaluar los modos de falla y sus efectos en un sistema. No está directamente relacionada con el principio 80/20.
    • Ishikawa Diagram (Diagrama de Ishikawa o Diagrama de Espina de Pescado): Es una herramienta utilizada para identificar las causas raíz de un problema, pero no se enfoca específicamente en el principio 80/20.
    • Histogram (Histograma): Es una representación gráfica de la distribución de datos. Aunque puede mostrar la frecuencia de problemas, no se enfoca en el principio 80/20.
    • Pareto Diagram (Diagrama de Pareto): Es una herramienta que se utiliza específicamente para aplicar el principio de Pareto, mostrando gráficamente cuáles son las causas más significativas de un problema.
  3. Conclusión: La herramienta que se utiliza para encontrar cuándo el 80% de los problemas pueden ser atribuidos al 20% de las causas es el Diagrama de Pareto.

Por lo tanto, la respuesta correcta es: 4. Pareto Diagram
