This paper discussed six sigma implementations in Indonesian manufacturing industries that identifies sigma levels from various manufacturing sectors and summarizes current evidence that contributes to revealing the current sigma level. This study reviews six sigma project cases from one of six sigma consulting firms in Indonesia. Six sigma project cases were collected from 2019-2022, the total project cases during that period included 120 six sigma project, and 58 projects that meet the criteria has been selected for this study. The results show that from 58 selected projects, the average sigma value of the observed industries was 3.7 before improvement and 4.1 after improvement. However, the highest sigma level before improvement was 4.8 which came from fast moving consumer goods (FMCG) sector and the highest sigma level after improvement was 5.4 which came from the packaging sector.
