Aplicação do gráfico de Gantt em microempresa de confecção para otimização do planejamento operacional

Abstract

The lack of operational planning in manufacturing micro-enterprises and the possible risks inherent to this lack of planning were identified in the literature, especially in relation to production control, which could be overcome by the Gantt chart. The presente case study analyzes the utilization of Gantt's graph by three manufacturing micro-companies, in search of the optimization of the operational planning. The Gantt chart (checklist that relates activities with time) could meet the needs of following the short-term plans of the manufacturing micro-enterprises due to its ease of use, agility, effectiveness and not requiring specialized personnel to use it. . On-site training was carried out with three micro-manufacturing companies so that they could use the Gantt chart and it was proposed that they use it during the making of a batch. After completion of the batch, the Gantt chart was analyzed and data collected on its immediate impact on short-term microenterprise plans. For quantitative analysis of the impact of the Gantt tool on optimizing the operational planning of micro enterprises, closed questionnaires with the Lickert scale were applied before and after the experiment with the graph. It was concluded that the companies that were most positively impacted by the use of the chart were the ones with the greatest inefficiencies in the existing informal operational planning due to difficulties in the operation of the product, one due to the complexity of the manufactured products and the other for a short time in the market. The company with the lowest acceptance was the longest in the business, making only one product, having no difficulties with short-term plans.
