Abstract
La presente investigación tiene como objetivo determinar cómo influye la implementación de
herramientas de manufactura esbelta en la productividad de la empresa Geral Calzados 23 S.A.C.
Por lo cual, se utilizó un estudio de tipo aplicada con un diseño Pre-experimental donde se evaluó
el comportamiento de la productividad, antes y después de la implementación, considerando una
muestra no probabilística por conveniencia del investigador en proximidad geográfica con los
operarios de la línea de producción. Además, las técnicas usadas para determinar la productividad
inicial fueron la observación, encuestas, entrevista y análisis documental. Se comenzó realizando
un VSM para identificar las causas principales de una baja productividad, donde el autor
convenientemente implementó la estandarización y 5´s en las estaciones críticas. Obteniendo como
resultado una productividad inicial promedio de 0,29 docenas/hora-hombre, el cual luego de
implementar la estandarización, donde se estableció un método de trabajo mejorado, reduciendo
un 13,08 % el tiempo de procesamiento y un 28,35 % el tiempo de cuello de botella, asimismo, se
logró un cumplimiento del 68,6 % de las 5’s. Por último, se evaluó la productividad post
implementación, dando como resultado un promedio de 0,4 docenas/hora-hombre, por ende, se
concluye que la implementación de herramientas de manufactura esbelta en la empresa Geral
Calzados 23 S.A.C. influye positivamente a la productividad en un 39,12 %.
The objective of this research is to determine how the implementation of lean manufacturing tools influences the productivity of the company Geral Calzados 23 S.A.C. For this purpose, an applied study with an pre-experimental design was used to evaluate the behaviour of productivity, pre- and post-implementation, considering a non-probabilistic sample for the convenience of the researcher in geographical proximity to the operators of the production line. In addition, the techniques used to determine initial productivity were observation, surveys, interviews and documentary analysis. A VSM was started to identify the main causes of low productivity, where the author conveniently implemented standardisation and 5's in the critical stations. Obtaining as a result an initial productivity of 0,29 dozens/hour-man, which after implementing the standardisation, an improved working method was established, reducing the processing time by 13.08 % and the bottleneck time by 28,35 %, also, a compliance of 68,6 % of the 5's was achieved. Finally, post-implementation productivity was evaluated, giving as a result 0,4 dozens/hour-man, therefore, it is concluded that the implementation of lean manufacturing tools in the company Geral Calzados 23 S.A.C. positively influences productivity by 37,93 %.
