The 5S methodology—Sort, Set in Order, Shine, Standardize, and sustain—is a foundational lean management tool aimed at improving workplace organization, efficiency, safety, and quality. While 5S has been extensively applied in manufacturing environments, its operational implications in service-oriented technical sectors such as the vertical transportation industry remain underexplored. The vertical transportation sector, which includes elevator and escalator design, installation, maintenance, and modernization, demands high operational reliability, safety compliance, and process efficiency.
This study examines the operational implications of 5S implementation in the vertical transportation sector. The research focuses on understanding how 5S practices influence operational efficiency, safety performance, maintenance effectiveness, quality of service, and employee productivity. A descriptive research design was adopted, and primary data were collected from 200 employees working in vertical transportation companies through a structured questionnaire. Statistical tools such as percentage analysis, mean score analysis, correlation analysis, and ranking techniques were used to analyse the data.
