Application of LEAN Concepts to Develop Service Procedures for the Computerized System Management: A Case Study of 1ST Army Area
Keywords:
Lean Thinking Application, Computer Equipment Maintenance Management System, User SatisfactionAbstract
This research aimed to study and improve the computer equipment maintenance management process by applying Lean Thinking, to design and develop a computer equipment maintenance management system, and to evaluate user satisfaction. The study was conducted as research and development, with a sample of 30 government officers from the First Army Area Command selected through purposive sampling. The system development followed the System Development Life Cycle (SDLC), including requirement analysis, system design, development, testing, and implementation. ReactJS was used for front-end development, Node.js for back-en processing, and MySQL for database management. The developed system supports efficient maintenance management and provides a structured approach to data handling. The results indicated that the developed system reduced the number of workflow steps from 14 to 7, shortened processing time from 335 minutes to 172 minutes, and decreased waiting time from 267 minutes to just 10 minutes. Non-value-added (NVA) steps were reduced from 11 to 1, while value-added (VA) steps increased from 3 to 6. Additionally, paper usage was completely eliminated. User satisfaction evaluation showed the highest overall rating (x̄ = 4.56, S.D. = 0.31), particularly in system efficiency, reliability and security, and system usability, demonstrating that the developed system effectively met user needs and research objectives.
