Purpose – The purpose of this paper is to investigate a lean manufacturing metric called Takt time as a benchmark evaluation measure to evaluate a public hospital’s service quality. Lean manufacturing is an established managerial philosophy with a proven track record in industry. A lean metric called Takt time is applied as a measure to compare the relative efficiency between two emergency departments (EDs) belonging to the same public hospital. Outcomes guide managers to improve patient services and increase hospital performances. Design/methodology/approach – The patient treatment lead time within the hospital’s two EDs (one department serves male and the other female patients) are the study’s focus. A lean metric called Takt time is used to find the service’s relative efficiency. Findings – Findings show that the lean manufacturing metric called Takt time can be used as an effective way to measure service efficiency by analyzing relative efficiency and identifies bottlenecks in different departments providing the same services. Originality/value – The paper presents a new procedure to compare relative efficiency between two EDs. It can be applied to any healthcare facility.

In today’s emerging world, as the demands and expectations of the people grow higher and higher every day, so is the competition. Thus to face the demand and to be competitive & survive in the market, industries have to produce superior quality components without producing waste. This leads every manufacturer to optimize and standardize the processes of every component being produced. One such concept employed is ―Lean Manufacturing‖. In this paper a novel tool in lean manufacturing is applied. The processes are continuously monitored and collected necessary data to generate VSM and declare the CSM based on the available data. Then the takt time graph and the balanced time – Cycle time – Downtime graph were plotted with the help of which, the scopes for improvements are identified and then the targets are obtained. The FSM is also drawn and a time plan for projects is prepared and monitored continuously. Based on the type of process and the project, different tools are adopted to reduce the cycle time, downtime, waste and thereby increase the productivity. By implementing newer tools, the future demand of the process was successfully proved to be met by the existing line itself and the need of an additional line was defeated, thereby making monetary savings. By implementing this system, the productivity can be constantly increased.

Benchmark Evaluation

Purpose – A lean manufacturing metric called Takt time is used as a benchmark evaluation measure to evaluate service quality at fast food restaurants. The metric is applied to find the relative efficiency between three fast food restaurants belonging to different chains. The purpose of this paper is to help guide management through ways to improve customer service and increase performance. Design/methodology/approach – The customer lead time (the time taken by a customer from arrival at the service queue until their order is fulfilled) is the focus of this study. Takt time is used to find the relative efficiency of service time between three fast food restaurants. Findings – It is shown that Takt time can be used effectively to measure the level of efficiency of the services provided. It measures the relative efficiency and identifies bottlenecks among different entities providing the same services. Practical implications – The results can be used as a guide to rank the efficiency of the length of service time of different entities by taking the whole system into consideration rather than just measuring and comparing the service time itself between the entities. The results show the effectiveness of using lean manufacturing practices in pinpointing the relative inefficiencies between different service provider facilities. Originality/value – This research presents a procedure to measure relative efficiency between different service providers to enhance their services. It can be applied to any service management systems that deal directly with walk-in customers.

A busca pela melhoria contínua é um conceito cada vez mais presente no cotidiano das empresas, as perdas no processo não são mais aceitas quando podem ser evitadas. Este projeto de pesquisa foi elaborado tendo como base a necessidade do aperfeiçoamento das atividades desenvolvidas pela empresa, neste caso um curtume catarinense. Para identificar as perdas do processo foi desenvolvido o fluxograma da empresa, além de abordar a metodologia Toyota de produção e o Lean Manufacturing que trata-se de um sistema produtivo que tem como objetivo enxugar suas atividades, entre outras ferramentas da qualidade como o Just in time, Kanban e Takt Time. Por fim apresenta o mapeamento do fluxo de valor, que é decorrente das atividades desempenhadas dentro da empresa que influenciam diretamente no beneficiamento do couro e valor agregado a essas atividades. Este projeto detalha cada um setores por onde o produto passa dentro da empresa, observou-se que as perdas de material são mínimas, mas a perda de valor agregado ao produto até que chegue ao ponto final do processo, que se caracteriza atualmente pela expedição do produto ao cliente, é considerado grande.

El estudio en la empresa “A” se realiza en una compañía líder de fabricación de equipos electrónicos para automóviles, principalmente en sistemas de seguridad y de audio, localizada en Málaga, España. El estudio consistió en mejorar la línea de producción 560A DA (ensamble de radio para el nuevo modelo de automóvil que lanzará Toyota en el 2018) mediante el uso de herramientas de lean manufacturing. Se analiza la línea para evaluar los principios de lean manufacturing y encontrar oportunidades de mejora. Al iniciar el estudio el desempeño del balance de línea con 8 operadores era de 72,72% y cada trabajador producía 30 unidades por turno de trabajo. Al eliminar mudas, disminuir desplazamientos y mejorar el ciclo de trabajo del operador se logra balancear la línea a 6 operarios aumentando el desempeño de la línea a 84,20% y cada operador produce 33 unidades por turno de trabajo. Se analiza el puesto de trabajo mediante la herramienta “strike zone” con el fin de verificar que las herramientas e insumos se encuentran al alcance del trabajador. Además, se efectúa un estudio detallado de los ciclos de trabajo para así clasificar las operaciones en actividades que agregan y no agregan valor. Durante el estudio, se identificó que la estación de prueba “Application” era causa de retrasos en el ciclo de trabajo del operador. Para concluir, se desarrolla una propuesta de ampliación de capacidad; la cual se aprueba para ser implementada en el mes de noviembre dado un aumento en la demanda de radios. El takt time para la línea ampliada sería de 80 segundos y según la propuesta el desempeño de la línea se espera sea de 95,51%.

Perkembangan teknologi dan globalisasi meningkatkan persaingan pada industri manufaktur. Agar dapat bertahan dalam persaingan bisnis, perusahaan manufaktur harus memenuhi permintaan dan memuaskan pelanggan dengan meningkatkan produktivitas dan efisiensi. Produktivitas dan efisiensi dapat ditingkatkan dengan mengurangi lead time. Lean manufacturing telah terbukti dapat meningkatkan produktivitas dan efisiensi dengan mengurangi lead time dari proses produksi. Studi ini bertujuan untuk meluaskan pemahaman tentang bagaimana lean manufacturing dapat mengurangi lead time dan memahami tantangan yang mungkin muncul. Lead time dari proses produksi dapat dikurangi dengan menggunakan bantuan pendekatan diagram SIPOC, peta aliran proses, penghitungan takt time, model evaluasi pemborosan, dan kuesioner evaluasi pemborosan. Namun, penerapan lean manufacturing untuk mengurangi lead time akan menjadi tidak efektif apabila perusahaan tidak siap dalam hal pengelolaan manajemen sumber daya, manejemen manusia, dan standardisasi.
