Can lean be mean? : A study of negative consequences of lean in supply chains

Johansson, Emma January 2010 (has links)
Today's world is characterized by volatility and uncertainty. Cooperation is needed to survive in this harsh business climate. Cooperation in supply chains are practiced and well known but in today's tough and volatile environment it is simply not enough. Wastes and unnecessary processes have to be eliminated to secure a competitive advantage. Incorporating lean in supply chains get more and more attention and embrace in the modern literature and media. Lean implemented in supply chains is praised to create a proactive supply chain that successfully eliminate waste and create efficiency. In the thesis the negative aspects, the angle that is very seldom described in the literature, of incorporating lean in supply chain is researched. I will view lean from the management perspective and research the negative aspects, their cause and impact on the entire supply chain. Being aware of the criticism of lean from the employee and society perspective this research serves to find if lean from the management perspective is a flawless story. To achieve the aim of this thesis I conducted a survey research where 100 supply chain executives from different countries, different industries and of different designations within supply chain management were asked to share their lean experience. The summary of my research show that lean incorporated in supply chains is not only a sunshine story. I can conclude problems, even a mismatch, with the lean concept incorporated in supply chains- the time sensibility lean brings. In my research it became obvious that lean supply chains are very sensitive to delays and that the consequences of the delays will strike very hard - hence the lean supply chain can also be seen as more vulnerable and fragile compared to ordinary supply chains. There is no question about the fact that any company, any network of companies or a supply chain for that matter, are better off without delays. A delay will always be negative. In a lean environment, where time aspects such as Just-In-Time and a pull scenario are present, a delay will immediately ruin the entire execution and the consequences will naturally spread in the supply chain. In today's volatile and ever changing world I believe that leanness in supply chains are indeed needed but to an extent where the time factors are viewed realistically in order to avoid drastic consequences. My conclusion is that supply chains should be realistically lean, bearing the time factors of lean in mind, to avoid being mean. I encourage every supply chain to identify their lean level in order to avoid a mean result.

No. of bitstreams: 1 oliveira_cvm_me_tupa.pdf: 2238562 bytes, checksum: 4ea0ca28386966e61e61aa15bfae4927 (MD5) Previous issue date: 2018-02-08 / O Brasil está entre os países que mais exportam couro. O segmento de couro possui importante papel na contribuição do desenvolvimento econômico de várias cidades brasileiras. O estado de São Paulo é destaque na produção de couros, juntamente como o estado do Rio Grande do Sul. Neste processo ocorre o beneficiamento do couro, sendo repassado para indústrias que elaboram roupas, sapatos, acessórios, e diversos outros produtos. Essas organizações, denominadas de agroindústrias processadoras de couro, estão em busca de uma gestão eficiente, que contemple toda produção, visando o aumento do resultado financeiro, possibilitando a continuação da atividade. Para tanto, a redução de desperdícios e ganho na qualidade são requisitos fundamentais para essa gestão. Diante da carência de estudos, a presente pesquisa tem como objetivo geral diagnosticar por meio da Lean Supply Chain Management (LSCM) aspectos de melhoria na gestão do elo curtume da cadeia do couro do Oeste Paulista. A abordagem da LSCM sendo aplicada corretamente cumpre os requisitos buscados pelas organizações. Para atingir o objetivo da pesquisa, utilizou-se como método de pesquisa o estudo de caso do tipo múltiplo, com a condução de visitas in loco e aplicação de formulário em cinco Unidades de Pesquisa, caracterizando os portes das organizações, os tipos de processos que elas fazem, quais os elementos e pilares que mais precisam de suporte referente à abordagem empregada, quais as ferramentas utilizadas que se enquadram na LSCM e os benefícios e dificuldades da aplicação. Destacam-se como resultados da coleta de dados que os pilares da Gestão da Tecnologia de Informação, Gestão Logística e Melhoria Contínua são os que mais carecem de melhorias, necessitando empregar a tecnologia da informação na comunicação com os clientes, planejar a rede logística de distribuição, direcionar equipes de trabalho para melhoria contínua. Os planos de ação para elaborar como serão realizadas as ações supramencionadas são oportunidades de futuras pesquisas. / Brazil is among the countries that export the most leather. The leather segment plays an important role in the contribution of the economic development of several Brazilian cities. The state of São Paulo is prominent in the production of leather, along with the state of Rio Grande do Sul. In this process the leather is processed, being passed on to industries that manufacture clothes, shoes, accessories, and various other products. These organizations, called leather processing agroindustries, are in search of an efficient management that contemplates all production, aiming to increase the financial result, allowing the continuation of the activity. Therefore, waste reduction and quality gain are fundamental requirements for this management. In view of the lack of studies, the present research has as general objective to diagnose, through the Lean Supply Chain Management (LSCM), aspects of improvement in the management of the tannery chain link of the leather chain of Oeste Paulista. The LSCM approach being applied correctly meets the requirements sought by organizations. In order to reach the research objective, a multiple-case study was used as the research method, with the conduction of on-site visits and application of the form in five Research Units, characterizing the organizations' sizes, the types of processes that they do, which elements and pillars most need support regarding the approach employed, which tools are used that fit the LSCM, and the benefits and difficulties of the application. It is highlighted as results of data collection that the pillars of Information Technology Management, Logistics Management and Continuous Improvement are the ones that need the most improvement, needing to use information technology in communication with customers, to plan the distribution logistics network, to direct work teams for continuous improvement. The action plans to elaborate how the aforementioned actions will be carried out are opportunities for future research.

Lean from an interorganisational perspective : a study of five different interfaces / Lean ur ett interorganisatoriskt perspektiv : en studie av fem olika gränssnitt

Hassel, Victoria, Modie, Malin January 2010 (has links)
Background: Lean has had a great influence on how companies work today, and both academics and practitioners have admitted its link with superior performance and the ability to create competitive advantage. There is however a widespread confusion of what lean really is and the absence of a clear definition has been highlighted by many researchers within the field. Since the birth of lean, a lot of focus has been on the internal perspective of the concept. Although today with an increased globalization, higher customer demands and a severe competition, the work with lean between companies becomes highly appropriate. Within companies, the processes often work effectively, but it is in the interfaces between companies where a lot of waste and possibilities to improvement exist. Aim: The purpose is to analyse the companies’ consciousness of lean and to what extent their understanding of lean can influence the effectiveness of the entire value stream. Furthermore, the purpose is to analyse how this consciousness affects the collaboration between a customer and a supplier. Method: The study has a deductive approach where the starting point has been in the theories within lean, supplier partnership and effectiveness. A multiple case study has been conducted where five different interfaces have been studied. The study has a qualitative approach where the empirical findings come from ten semi-structured interviews. Result: Our study shows that working with lean interorganisationally helps to create a higher performing value chain. For companies working with lean internally, it is also natural working with lean with the partners. From a lean perspective, effectiveness is defined as a reduction of cost through elimination of waste. By performing VSM, having regular evaluating meetings, sharing forecasts and giving each other insight in inventories, a lot of waste in the interfaces can be reduced. However, to have a well working collaboration, the study shows that a high level of trust and a common view and attitude towards collaboration are necessary.

A Study on the Implementation of Green Supply Chain- A Comparative Analysis between Small Scale Industries in India and Developed Nations

Selvaraj, Ranjith Karthick January 2011 (has links)
Environmental pollution is the major problem that mankind faces in present state, the major emission of toxic gases is from vehicles and manufacturing industries. The thesis study focuses on three different types of Small Scale Industries (SSI) in India that are bumper manufacturing industry, dyeing industry and food processing industry. The product life cycles of the process for each industry are identified and their final green waste disposal methods are investigated. The industries are identified with more lean wastes within their product life cycle process. The major green wastes from their disposal methods have high influence on environment. These wastes have to be reduced or eliminated by practicing a suitable supply chain. In present the companies doesn’t practice any supply chain in their organization. The implement of supply chain could reduce the environmental pressures and wastes of the companies to some extent. The lean wastes identified in the process could be eliminated by practicing suitable lean tools and methods. The final disposal wastes are considered to be the green wastes. The method of disposal practiced by the SSIs in India shows an evidence of how much they concern towards the environment. The research tries to explain some suitable waste management techniques for the industries and discusses about importance of government role on making this techniques possible. The small scale industries experiences both wastes, so it has to integrate lean for practicing green supply chain, the implementation of lean would pay a way for green supply chain management. As a result of it a comprehensive lean and green model is suggested for the industries because the model is composed of both lean and green waste reduction techniques and it also helps in achieving both lean and green business results.
