This paper aims to analyze the impact of applying established quality management methodologies—specifically the Ishikawa Diagram, the 5 Whys technique, and the 5S methodology—on the optimization of telecommunications maintenance processes. The study proceeds from the premise that the stability of Gigabit Passive Optical Networks (GPON) and Hybrid Fiber Coaxial (HFC) networks relies not only on technological robustness but also on the efficiency of field and management procedures. Through a case study based on continuous improvement projects (TESP and PAQ) at a major Brazilian operator, this research demonstrates how structured root cause investigation facilitated a reduction in the volume of Service Orders (OS) in the state of Santa Catarina. A deductive methodology with an empirical-analytical approach is employed, grounded in a literature review and the analysis of operational results. It is concluded that tool standardization and critical failure analysis are essential drivers for reducing operational expenditure (OPEX) and enhancing end-customer satisfaction.
