Behind The Machines: Mechanical Engineers’ Perspectives on Preventive Maintenance and Ensuring Industrial Reliability

Preventive maintenance (PM) is critical for ensuring industrial asset reliability, efficiency, and safety. This qualitative phenomenological study explored the perspectives of 12 mechanical engineers in Tarlac regarding PM strategies, implementation challenges, and the influence of personal and organizational factors on asset reliability. Data were collected through semi-structured interviews and document analysis, then analyzed using thematic analysis, resulting in three major themes: (1) diverse conceptualizations and implementation of preventive maintenance, (2) facilitators and barriers to effective PM, and (3) the influence of personal beliefs, organizational culture, and industry dynamics on maintenance practices. Findings reveal that engineers’ engagement with preventive maintenance is shaped by technical expertise, organizational support, resource availability, and individual initiative, while barriers such as tight budgets, outdated equipment, and operational constraints limit full implementation. The study underscores the need for a holistic approach that integrates technical training, organizational strategies, and supportive policies to enhance preventive maintenance practices in regional industries. Recommendations include professional development, modernization of equipment, structured maintenance programs, and policy initiatives to support sustainable and effective PM practices in the Philippines.
