This article deals about the application of the Six Sigma methodology by using modern methods in various stages of the DMAIC improvement model. The change management of business processes in terms of quality is determined by the correct choice of methods and tools for reducing discrepancies and non-productive costs. The evaluation of selected processes of furniture production through defects per million opportunities, efficiency, capability and sigma level before the change and after the change in the quality process provides relevant information for ensuring continuous quality improvement. Implementation of assessing changes in the process is a source of information for continuous improvement of process performance. Keywords: Processes, quality improvement, Six Sigma, DMAIC, changes in processes.

296 Background: Initiating a new clinical trial is burdensome and complex. The time to activate a clinical trial can directly affect the ability to provide innovative, state-of-the-art care to patients. We sought to understand the process of activating an oncology clinical trial at a matrix National Cancer Institute-designated, comprehensive cancer center. Methods: A multidisciplinary team of stakeholders within the cancer center, university, and affiliate hospitals held a retreat to map out the process of activating a clinical trial from packet receipt to enrollment of the first patient. We applied classical QI and Six Sigma methodology to determine bottlenecks and redundancies in activating a clinical trial. During this process, particular attention was paid to time to pass through each step and perceived barriers and bottlenecks were identified through group discussions. The time to activation was measured from the day the trial packet was received until the time when the trial was open for enrollment. Results: The process map identified 66 steps with 12 decision points to activate a new clinical trial. The following two steps were instituted first: 1) allow parallel scientific committee and institutional review board (IRB) review and 2) allow the clinical research coordination committee to review protocols for feasibility and university interest separate from the IRB approval process. These changes resulted in a mean time-to-activation change from 194 days at baseline to 135 days after these changes were implemented. The committee continues to track the activation time and this frame work is used to identify additional improvement steps. Conclusions: By applying quality improvement methodologies and Six Sigma principles, we were able to redesign redundant aspects of the process of activating a clinical trial at a matrix comprehensive cancer center. This was associated with a reduction of time to activation of trials. More importantly, the process map provides a framework to maintain these gains and implement further changes.

Purpose The purpose of this paper is to study the anodising process of a portable amplifier production process to identify and eliminate the sources of variations, in order to improve the process productivity. Design/methodology/approach The study employs the define-measure-analyse-improve-control (DMAIC) Six Sigma methodology. Within the DMAIC framework various tools of quality management such as SIPOC analysis, cause and effect diagram, current reality tree, etc., are used in different stages. Findings High rejection rate was found to be the main problem leading to lower productivity of the process. Four types of defects were identified as main cause of rejections in the baseline process. Pareto analysis resulted in detection of the top defects, which were then analysed in details to find the root cause of the problem. Further study resulted in finding improvement measures that were discussed with the management before implementation. The process is sampled again to check the improvements, and control measures were established. Practical implications The study provides a framework for implementation of DMAIC Six Sigma methodology for a manufacturing firm. The results presented are based on the data collected from the shop floor. Results and findings of the study were implemented for quality improvement of the process. Originality/value The study is based on an original research conducted with the objective of quality improvement in the anodising process of the production process. Besides presenting an approach to DMAIC Six Sigma methodology, an application of the current reality tree tool for root cause analysis is presented, a tool used limitedly in the Six Sigma studies. The tool finds its uniqueness in its ability to address problems relating multiple factors than isolated factors.

Six Sigma Methodology

Six Sigma is one of methodologies of the quality management for the process improvement. It can be used in manufacturing companies, in order to achieve certain criteria established by management or customer requests. Six Sigma is based on the assumption that opportunities for success are hidden in every process and it gives the company a common tool for defining of corporate objectives. Implementation of this methodology lies in the integrated approach in solving the problems of business processes, which can represent significant benefits in production processes as well as various non-production processes. Six Sigma is based on the principle of measuring, monitoring and controlling processes with possible application of statistical methods, different tools and techniques. If the Six Sigma methodology is used properly and rationally, companies can save considerably with this effort the measurable financial resources. Its application leads to a cost reduction in inefficient processes, contributes to the production quality, better performance and to the satisfaction of internal and/or external customers.The objective of the paper is to present base theoretical aspects of Six Sigma framework and its principles. Followed with methodology of Six sigma and in addition is addressed a concrete application for statistical process control of the lacquering process within silencers manufacturing for a company in the automotive industry. The practical contribution of the project provides an improvement of the process, which means to improve the product quality, achieve cost reduction and better customer satisfaction.

Abstract Introduction/Objective DMAIC (an acronym for Define, Measure, Analyze, Improve and Control) refers to a data- driven improvement cycle used for improving, optimizing, and stabilizing business processes and designs. Our goal was to utilize DMAIC principle of six sigma quality to improve histology slide quality. Methods/Case Report We “defined” the problem as suboptimal quality in endometrial biopsy slides (defects). Utilizing the DMAIC principle and adhering to a strict timeline, the defects found during baseline slide quality review were “measured” by linking the defects to specific histology competencies, which were addressed systematically for process improvement (PI). After PI, a follow up review (“improve” and “control” phases) was carried out to identify measurable outcomes as a testament to quality. Results (if a Case Study enter NA) During the problem “measurement” phase, the defects found in the baseline review of 175 slides were linked to four specific histology competencies (fixation, embedding, cutting, and staining). Processing was excluded as it is completely automated and standardized. Our analysis showed that 83.3 % of defects were linked to embedding (“tissue too dispersed”). As embedding competency depends on the size and nature of the tissue (e.g. mucus and blood admixed with tissue), grossing competency was also addressed along with embedding at the respective workstations. Recommendations were offered to the grosser, embedder, and cutter to reduce variables during the “improvement” phase. Follow up review was done on 196 slides. The number of defective slides decreased and the defects that linked to “tissue too dispersed” had an overall improvement of 91.3%. Once the PI is proven to be effective, in service to histotechnology personnel biannually were also offered during “control” phase. Conclusion We have demonstrated successful methods for improving histology slide quality utilizing DMAIC principle of quality improvement by six sigma methodology DMAIC principle can be creatively adapted in laboratory practice management to enhance quality.
