Application of Quality Management Tools to Reduce Costs with Scrap in the Automated Teller Machine Industry

Abstract

Globalization has increased competitiveness among markets, leading companies to optimize their production processes to reduce scrap and costs. This study presents the application of quality tools in the automated teller machine (ATM) industry to minimize financial losses associated with material rejection. The study employed tools such as Pareto diagram, trend analysis, scatter diagram, 5 Whys analysis, and 5W2H to identify the main causes of material rejection. The results showed that implementing these tools reduced rejection costs by 95% between 2018 and 2020, with sustained reductions in 2021, proving the effectiveness of the actions taken.
