Aplicação da manufatura enxuta em uma indústria de equipamentos agrícolas

EnglishWith increasing competition and the need for improved competitiveness, companies who adopt the lean production system have some advantages, because they deal better with the information, increasing their efficiency. The objective of this study was to decrease the lead-time required by the studied company, by practical application of just-in-time searching for lean production in a metalworking company, manufacturer of agricultural implements. To meet this purpose, a case study of qualitative and descriptive order was carried out. To collect data, observation and documental analysis were performed, in order to understand the production processes, then working with the collection of data, through structured interviews in order to identify the difficulties encountered by suppliers in providing the supplies within the agreed specifications. The company had high indexes of late delivery of their products because of the high lead-time. Through the development of the mapping of actual flow, it was found that the organization was working with a production pushed and much of the late occurred because of problems in the supply of inputs. By eliminating tasks that did not add value to the final product, a lean value flow was produced for the process, identifying the major problems which caused the suppliers to provide the supplies out of specification or out of date and suggested actions that could be implemented for the elimination of these delays. Through these actions, the reduction in lead time was observed, helping to better meet delivery deadlines, increased competitiveness, a relevant fact to keep in today�s market of agricultural equipment. portuguesCom a crescente concorrencia e a necessidade de maior competitividade, as empresas que adotam o sistema de producao enxuta levam vantagem sobre as demais, pois tratam melhor as informacoes aumentando a sua eficiencia. O objetivo desta pesquisa foi diminuir o lead-time da organizacao estudada, atraves da aplicacao pratica do Just-in-time em busca de uma producao enxuta em uma empresa metal-mecânica, fabricante de implementos agricolas. Para atender a este objetivo realizou-se um estudo de caso de natureza qualitativa e de ordem descritiva. Para a coleta de dados utilizou-se inicialmente a observacao e a analise documental para entender o processo produtivo.

A empresa estudada apresentava alto indice de atraso na entrega de seus produtos, devido ao elevado lead-time. Atraves da elaboracao do mapeamento de fluxo atual, identificou-se que a organizacao trabalhava com uma producao empurrada e que muito dos atrasos ocorriam por problemas no fornecimento de insumos. Buscou-se a eliminacao de tarefas que nao agregavam valor ao produto final, elaborou-se um fluxo de valor enxuto para o processo, identificaram-se os principais problemas que levavam os fornecedores a entregarem os insumos fora das especificacoes ou dos prazos e sugeriram-se acoes que poderiam ser aplicadas para eliminacao destes atrasos. Atraves destas acoes observou-se a reducao no lead-time, auxiliando no melhor atendimento dos prazos de entrega, no aumento da competitividade, fato relevante para manter-se no mercado atual de equipamentos agricolas.

O processo empreendedor em empresas criadas por necessidade

Creating firms is an inherent entrepreneurial spirit. When necessity is the motivation, the risk of failure is high. The objective of this study is to understand and share the learnings and experiences of an entrepreneurial group that was faced with this challenging situation and reached success. From the theoretical point of view of the authors who dealt with the entrepreneurial process, the case study aimed to establish a relationship between theory and practice through interviews with entrepreneurs. Once this relationship was established, a model of entrepreneurial action that can guide other entrepreneurs in similar situations was suggested. It was observed that the idea of having their own business motivated the entrepreneurs and the feedback received stimulated changes. Prudent entrepreneurship, the business created, and the environment favored this situation. While developing entrepreneurial experiences, these entrepreneurs, influenced by different types and styles of management, changed their own management approach and developed the entrepreneurial process. This behavior speeded up changes leading to high levels of accomplishment.
