The improvement of a quality assurance information systems Based Six-Sigma Principles

Abstract

This paper presents the development of a quality assurance information system based on Six-Sigma principles for schools in northern Thailand. The aim of this research is to solve problems that occurred in a previous system. These included an awkward user interface, support without quality standards, user confusion in the workflow, along with inaccurate and unreliable information system processes. Six-Sigma uses five processes. These are the define, measure, analyze, improvement, and control phases (DMAIC). According to previous studies, measurement of user satisfaction and expectations has three components: standards-based service, system reliability, and processing speed. Technical and non-technical quality measurements indicated that the initial system operated at a 2-sigma level. These measurements confirm that the proposed system provides the improved services over the initial system and that it effectively solved many of its problems. Moreover, it raised the efficiency of the service system based on quality assurance standards for the mission of the schools in the northern region.
