    This study identifies and prioritizes critical success factors (CSF) based on the implementation of Lean Manufacturing for Thai SMEs. After review of International research papers, 12 CSFs were selected and categorized into four resource types from the lens of Resource-Based View (RBV) Theory. These are Organizational, Technology, Human and Financial Resources. Interviews and surveys with Lean experts experienced in SME consultation were carried out to answer the proposed research questions. Analytical Hierarchy Process (AHP) is then applied to prioritize the relative importance of the CSFs. The results show that "Technology resource" is the most important to enhance implementation of Lean in SME organizations. This indicates the knowledge of production technology is a prime key to support process improvement according to Lean methodology. This study contributes to the existing body of knowledge by evaluating and prioritizing CSFs reflecting by grounded theory and expected outcomes at firm level from experts' experience.

    This paper aims to improve a production process of a laser computer mouse by using the Six Sigma DMAIC Methodology. This study focuses on the functional test procedure because of its lowest yield. The regression analysis and two-level factorial design of experiments is employed in order to determine the optimal conditions of parameters. By operating under these resulting conditions, yield of the functional test procedure increases from 96.2 to 98.6%. © 2013 Springer-Verlag Berlin Heidelberg.
