Abstract: This study is an application of Measurement System Analysis (MSA) technique to improve measurement system and create standardized work instruction. This analysis is to decrease and control the variance of measurement. MSA consists of section; section 1 is variable MSA that includes of 2 subsections. The first is analysis of location variation which consider on bias, stability and linearity. Second is the analysis of width variation which considered on repeatability and reproducibility. Section 2 is attribute MSA with consider on operator effectiveness, false alarm and miss rate. The result show that the variable MSA is within criteria and able to control ability of measurement. For the Attribute MSA there is ongoing problem which needs to be improved. Consequently, there is need for more root cause analysis by Fish Bone Diagram. It appears that operator has judged by referring a sample that the customer provided. That is not sufficient to obtain the effective accuracy. This result was conducted to take the action by settle limit sample in the process in order to reference defect sample. As a result, screen effective score is increasing from 40% to 90% and attribute screen effective score is increasing from 35% to 85%. There is improving the operator effectiveness and to be under acceptance. However, this study also improves variable MSA by creating the standardized work instruction to apply on QA final inspection process and this will extend to related process.
