This report is an initially study of the whole processes in the manufacturing aims to capturethe current problems into groups of categories and prioritize the problem solving according tothe frequency of the defects detection, the root causes are indentified and assessment ofFMEA on the problems occurrence.Research method is performed by interviewing the key persons who are representatives fromthe units, then use tools of quality improvement to analyze each step (Affinity, Pareto,Ishikawa and FMEA).Conclusion of the study found that Burapha Wood Company is currently facing with threecategories of problem, those are Machinery, Competency, Timber Drying and others with thelist of problem are consisted.The Two sided planer machine is a first prior to be undertaken of solution. Where the rootcauses are ignorance of workers not follow the machine’s instruction in such of reset themachine before operating and the record form has not filled when problems occurrence.The processes where the company has to focus is on the Two sided planer machine which is ahighest prioritized by pareto diagram based on FMEA analysis, but considering with thepotential and possibility of solution Burapha Wood Company must intend on timber drying.These problems are partial platform of improvement of manufacturing quality to get a COCcertification.
