Daiwa Massage Chairs by U.S Jaclean is a Japanese owned company that specializes in massage chairs, health, and wellness items. The company has 13 branches in the United States and has accrued approximately 200 employees within the last 40 years. After the COVID-19 pandemic, the company experienced a fluctuation of employees and was unable to retain them. The company has faced major backlash from employees that feel as though they lack training and a system to operate efficiently. The purpose of this project is to set the framework for decreasing the employee turnover rate and increasing productivity by implementing continuous improvement solutions. These solutions include the implementation of a training development plan, systematic checklists, documentation maintenance, emphasis on safety equipment, research on Department of Transportation (DOT), and optimizing the company equipment. Within the training development plan, continuous improvement tools were included like Standard Operating Procedures (SOPs), mistake-proof techniques, instructional videos, quizzes, and 5s improvement plans. Overall, the implementation of these strategies not only resolves immediate issues but also fosters a culture of continuous improvement and long-term competitiveness in the market.
