Abstract

The objective of this research is to study the problems, obstacles and improve the production process using lean concepts by focusing on eliminating waste and reducing lead time of the production process. The research takes the first step with studying workflow of each process in order to create a value stream mapping of the current situation. Next, the researcher analyze the process in each activity to identify waste and determine solution by using cause and effect diagram , the 5W+1H (What, Why, Where, When, Who, How) and ECRS techniques (Eliminate, Combine, Rearrange, Simplify). After the improvement, the result of this research found that the number of manufacturing process is decreased by 17.78 % and lead time is reduced by 9.69%.
