“…Second, in this measurement stage, defects per million opportunities (DPMO) and Sigma Quality Level are calculated to measure the performance process based on the number of defects per million opportunities (Girmanová et al, 2017). The following is the calculation with Excel software to evaluate DPMO (Erdoğan & Canatan, 2015) and a sigma level based on the following formula (Hernadewita et al, 2019), namely:…”

The research was conducted at PT. XYZ where there were defect problems in bed series products so that additional time is needed to repair a product. One way to make improvements and improve quality in a production process is the Six Sigma method with the stages of DMAIC. The results of the calculated average of DPMO values and Sigma Level have the result 58558.56 and 3.07 which are still not good because still far from 6 sigma. After that analyzing the root causes of defect product problems, then the priority problem is carried out using (RPN) where the highest value is at the assembly work station because the material that has been used up in the warehouse has an RPN of 405 so that it becomes a top priority for repairs. With the standardization and documentation, proposed improvements that have been given then the possible defects of Electric Lovina Bed 3 Motor will be reduced.

“…In this study, three DSS frameworks were reviewed and compared to provide the baseline structure for the integration of quality management tools into continuous process improvement at clinics. These were the benchmarking framework [20], multiple criteria decision analysis (MCDA) [21], and Six Sigma [19], [22].…”

“…Six Sigma is a methodology that can be applied to processes to eliminate the root cause of problems through problem-solving and improvement techniques [22]. In order to achieve the goal of Six Sigma, the 'define, measure, analyse, improve, and control' (DMAIC) methodology must be implemented to ensure the continuous improvement of processes through continuously reducing errors [19].…”

Product quality is an important factor that underlies the consumer's decision to choose the desired product and service. Quality can initially be determined by the company, but in subsequent developments, quality planning must pay attention to the wants and needs of consumers. In providing excellent service to customers, the company needs to apply the concept of lean thinking, intending to reduce waste. A methodology is needed that can reduce product variations, and production process errors with the Six Sigma methodology. The second application is often called Lean Six Sigma. This paper aims to improve the quality of fluid carrier tank products. The number of defective products, mainly on welding, cutting and bending process, so rework is needed that causes companies to suffer losses. The company expects to reduce product defects by less than 5%. The welding, cutting and bending process are the highest contributor to defective products, so that process improvement is limited to these processes. The process of welding, cutting and bending process is considered a major problem, so the main concern for quality improvement is for the main problem. Sigma, the initial welding, cutting and bending process in sequence is quite good. The target to be achieved is to increase the sigma value of both processes. The alternative is chosen, namely creating and supervising SOPs, and training to improve the skills, knowledge, and abilities of each employee. These alternatives can increase the sigma value from the initial conditions from 2.93 to 3.20. The increase in sigma value indicates a decrease in the level of defects per million opportunities (DPMO).
