Isi artikelSix Sigma is typical of the intense effort that world class companies are directing to quality management. It is a well-structured, data driven methodology for eliminating defects, waste, or quality control of all kinds in manufacturing. Six Sigma methodology is based on the combination of well-established statistical quality control techniques and data analysis methods. Statistically, the term Six Sigma defines an optimum measurement of quality: 3.4 defects per million events. To solve the quality problems happened at VARIA Workshop, is used Six Sigma methodology, well-known as Define, Measure, Analyze, Improve, and Control (DMAIC) phases. The DEFINE phase is concerned with the definition of goals and boundaries, and the identification of the problem. In this phase, is used project charter and process flow diagram to identify the problems. The goal MEASURE phase of Six Sigma strategy are to gather information about the current situation, to obtain baseline data on current process performance, and identify Critical To Quality (CTQ) characteristics. With pareto diagram, problems that have the greatest potential for improvement can be focussed by showing relative frequency and / or size in a descending bar graph.The goal of the ANALYZE phase of the Six Sigma quality effort are to identify the root causes of quality problems, and confirm those causes using the appropriate data analysis tools such as Statistical Process Chart (SPC) : Attribute Statistical Process Chart and Variable Statistical Process Chart, significancy test through hypotesis, and process capability analysis. The goal of the IMPROVE phase is to implement solutions that address the problems (root causes) identified during the previous phase (Analyze). Based on the analysis and brainstorming result with production staff, cause and effect diagram is made to illustrate what are possibly causing the problems. From the problem investigation with cause and effect diagram, the element that contribute to the problem tend to be placed in five groups such as : first, the machinery consists of cutting tools setting, machines maintenance, and machines damage; second, the raw material consists of supplier, material handling, and material warehouse; third, work method consists of work standard, shift turn over, and quality control, fourth the employee consists of carefulness, skill, tiredness, team solidarity, and dicipline, and the fifth, the work environment consists of work equipment arrangement, lighting, noise, and air circulation. From the problem investigation, some improvements those address the problems can be proposed. In the CONTROL phase, the results of the previous phase (Improve) are evaluated and monitored continuously.
