Implementation of Six Sigma Concept to Improve Software Product Quality at XYZ Company

Abstract

Information technology is growing so rapidly that many companies need software products to improve the efficiency and effectiveness of company operations. XYZ Company, which manufactures various software products to meet market needs, is aware that there are deficiencies in the quality of its products. These deficiencies can reduce customer satisfaction and have a negative impact on the company. Therefore, we need a good method to improve product quality. One method of quality improvement that is widely studied and applied by companies is Six Sigma. Six Sigma is a method that focuses on improving product quality that will increase the effectiveness and efficiency of all operational processes to meet satisfaction and customer needs using five stages of DMAIC namely Define, Measure, Analyze, Improve, and Control. The results of using the Six Sigma method is a continuous improvement program that is expected to assist companies in improving the quality of software products produced by utilizing information systems. In this research, we first formulate problems based on references from previous studies, then design research sampling using the Six Sigma concept. Based on five stages of DMAIC, this research results seven recommendations to be implemented to improve the quality of software products at XYZ company. After all the recommendations in this research are implemented, the estimated sigma level of the quality software products increases by 0.46σ (3.71σ to 4.17σ).
