High business competition demands business players to improve quality. The Six Sigma

with DMAIC phases is a strategy that has proven effective in improving product and service quality. This study aims to find the consistency of DMAIC phases implementation and

analyze the objective value in Six Sigma research. By using a number of trusted article

sources during 2005 until 2019, this research finds that 72% research in manufacturing industry consistently implemented DMAIC roadmap especially in case study research type

for problem-solving, while service industry pointed out the fewer number (60%). The causes

of variations and defective products in the manufacturing industry are largely caused by

a 4M 1E factor, while in service industry are caused by human behavior, and it’s system

poorness. Both manufacturing & service industry emphasized standardization & monitoring to control the process which aimed at enhancing process capability and organization

performance to increase customer satisfaction.
