From April 7 to 9, 2021, Bronco School of Management carried out a three-day Six Sigma yellow belt learning course for MIPS company. MIPS company, headquartered in Stockholm, Sweden, was founded in 2001. It is a Swedish listed high-tech company with international patents in R & D products, and its main customer group is well-known brands in the global helmet industry. In the classroom, the teacher introduces the students to the knowledge of Six Sigma in an all-round way and grasps the relevant tools and technologies in the practical operation. The classroom atmosphere is warm. Every communication and discussion is a process of collision of ideas and opinions between the teacher and the students. They can get more new ideas and opinions from this learning and communication process. The three-day study has made the students form the awareness of Six Sigma management. The students said that they would benefit a lot if they could apply these knowledge to practical work in the future!
