Abstract
Las empresas de la zona norte del Perú están sometidas a afrontar grandes desafíos que les
permita diferenciarse de sus competidores, teniendo como visión la expansión hacia otras
provincias o incluso poder competir con las grandes empresas de la capital. Es por ello que se
realiza la presente consultoría de negocios a la empresa lambayecana Krea Muebles, con la
finalidad de encontrar oportunidades de mejora y ofrecer alternativas de solución que les permita
alcanzar un alto desempeño y rentabilidad a largo plazo. Como primer paso se realizaron
entrevistas a la gerencia y a los colaboradores, así como visitas a la planta de producción y a la
tienda de la empresa, a partir de las cuales se elaboró un diagnóstico de la situación actual; en
éste, se detectaron tres problemas principales: (a) Sobreproducción de cascos en blanco y sofás
semi terminados, representando una pérdida económica de S/. 112,800.00; (b) Movimientos
innecesarios en la fabricación, que implica una pérdida de S/59,895.00 y (c) Tiempos de espera
para el uso de herramientas y maquinaria, con una pérdida de S/90,036.25, los cuales
ocasionaban una pérdida económica total de S/262,731.25 anuales. Posteriormente, se analizaron
los problemas y se diseñó un plan de mejora de procesos mediante el uso de herramientas Lean
Manufacturing con los objetivos de estandarizar los procesos, reducir el tiempo de producción, e
incrementar la eficiencia operativa; con la implementación del plan de mejora, la empresa Krea
Muebles redujo el tiempo de fabricación de 3,543.25 minutos a 660.84 minutos por unidad
fabricada, obteniendo un incremento anual de 184 unidades, que representan un ingreso de
ventas adicional de S/ 580,961.60. Finalmente, se estimó que esta implementación requiere de un
período de seis meses y una inversión de S/ 53,895.00, obteniendo como resultados esperados un
TIR de 42% y VAN de S/ 32,831.25 soles.
Companies in the northern part of Peru are subject to face great challenges that allow them to differentiate themselves from their competitors, with the vision of expanding to other provinces or even being able to compete with large companies in the capital. That is why this business consultancy is carried out to the Lambayan company Krea Muebles, in order to find opportunities for improvement and offer alternative solutions that allow them to achieve high performance and long-term profitability. As a first step, interviews were conducted with management and employees, as well as visits to the production plant and the company's store, from which a diagnosis of the current situation was made; In this, three main problems were detected: (a) Overproduction of blank shells and semi-finished sofas, representing an economic loss of S /. 112,800.00; (b) Unnecessary movements in manufacturing, which implies a loss of S / 59,895.00 and (c) Waiting times for the use of tools and machinery, with a loss of S / 90,036.25, which caused a total economic loss of S / 262,731.25 per year. Subsequently, the problems were analyzed and a process improvement plan was designed through the use of Lean Manufacturing tools with the objectives of standardizing processes, reducing production time, and increasing operational efficiency; With the implementation of the improvement plan, the company Krea Muebles reduced the manufacturing time from 3,543.25 minutes to 660.84 minutes per unit manufactured, obtaining an annual increase of 184 units, which represents an additional sales income of S / 580,961.60. Finally, it was estimated that this implementation requires a period of six months and an investment of S / 53,895.00, obtaining as expected results an IRR of 42% and NPV of S / 32,831.25 soles.
