Propuesta de mejora en el proceso de reparación de motores trifásicos mediante el ciclo DMAIC en una empresa de servicios electromecánicos

Abstract

< The objective of this project was to develop an improvement proposal and conduct a detailed analysis of the three-phase motor repair process using the DMAIC cycle. Various diagnostic tools were employed, and implementation improvements were suggested. The results focused on reducing waiting times and increasing FTQ. After analyzing the times for each work area, it was identified that the administration and rewinding areas had the longest waiting times. In the measuring and analyzing phases of the DMAIC cycle, it was observed that the estimated time increased by 0.83% compared to the forecast, and FTQ decreased by 20%. This gap was attributed to several causes identified through a Pareto analysis and prioritized with an Ishikawa diagram. Some of these causes included: lack of training, poor team communication, improper tool placement, inefficient plant layout, lack of time and quality indicators, incorrect task assignment, and job dissatisfaction. In the improvement phase, a 50% reduction in waiting time and a 10% increase in FTQ were proposed. To achieve these goals, several improvement tools were implemented, including a skills matrix, workplace climate evaluation matrix, optimized layout, future VSM, and RACI matrix. These measures will allow the company to have better control over its indicators and activities, avoiding order delays and increasing external customer satisfaction
