Abstract
The objectives of this research were 1) to investigate fermented tea leaf production processes and system by applying the Lean Thinking method to designate value-added activities as well as to eliminate wastes of the tea, and 2) to propose ways to increase production efficiency of fermented tea leaf producers at Tambon Papae in Mae Taeng District, Chiang Mai Province. The population consisted of 43 tea growers at Pang Ma Kluay village. The data were collected by group discussion and in-depth interview and observation with tea growers and group leaders in order to obtain two-way information. The research instruments consisted of the in-depth interview and the structured questionnaire. The content analysis was used to analyze the qualitative data and the analytic induction was used to analyze the data from the in-depth interview and observations. The quantitative data were analyzed to improve the production processes and the value stream mapping was utilized to examine the production efficiency. The analysis of the current status of the production processes revealed that there were wastes in the production system. The wastes included waste, unnecessary processes and waiting time. These wastes were eliminated by the operation guidelines after implementing the lean instruments. It was found that the total time from the entire processes could be reduced from 121,819 minutes (2,030.32 hours) to 121,762 minutes (2,029.36 hours) and labor force could be reduced from 26 to 22. In conclusion, the application of the value stream mapping management to the agricultural industry could increase the efficiency of the production processes and it could be applied well
