“…Snee (2010) defines Lean Six Sigma as a business strategy and, at the same time, a methodology that increases the process performance. Vinodh et al (2014) and Youssouf et al (2014) define Lean Six Sigma as a combination of tools and techniques that reduce variability and build on Six Sigma tools and methods for eliminating waste and added value. LSS is a method of improving quality and profitability based on mastering the stability of the process, and it is also a management style that is based on a highly regulated organisation dedicated to project management.…”

Most small and medium-sized enterprises in the furniture industry use simple partial approaches to improve or manage production processes. The article aims to present research results focused on continuous process improvement through the implementation of Six Sigma (SS) and Lean Six Sigma (LSS) concepts in furniture production. Their impact on the performance via the level of the ROE (Return on Equity) indicator was evaluated using statistical methods of Chi-square test and Cramer's contingency coefficient. The results of the research showed that furniture enterprises that had implemented selected methods of quality management reached a medium level of ROE values. The absence of a more comprehensive approach to managing the performance of processes was the impulse for a model creation based on the interconnection of SS and LSS concepts. The model should a practical use of appropriate methodologies and procedures in the management of furniture production processes, as well as in their optimisation. A thorough analysis of nonconforming products performed in furniture manufacturing processes transformed into SS and LSS metrics and the implementation of the model in the enterprise led to reduced process waste by reducing the number of non-conforming products, reducing the cost of such products, and increasing the capability of critical processes. Implications for Central European audience:The combination of theoretical knowledge in performance management and quality of production processes and practical knowledge from the real implementation of methods and tools for continuous improvement of production process capability in the company proved to be a good basis for creating a model within SS and LSS. These facts have contributed to the development of scientific knowledge. The presented application of methods and tools within SS and LSS will provide instructions for the use of new management methods. The specific outputs of the research work improve defining problems, measuring process parameters, analysis of measured data, improving furniture production processes.

Nowadays, the development of ICT devices is growing very rapidly. Many companies and governments invest a lot of funds on the ICT side to optimize and cut operational costs as effectively and efficiently as possible. This paper discussed the issue of the maintenance of ICT equipment in the Indonesian constitutional court which is spread in 42 locations throughout Indonesia. The current problem is that there is no maintenance of ICT in the Constitutional Court of the Republic of Indonesia in 42 cities throughout Indonesia, so it is difficult to overcome the technical problems that occur. In this paper, Six sigma is combined with several decision-making methods to minimize technical disturbances in the ICT device to the right selection of vendors to carry out the ICT maintenance. The proposed method that we did to optimize maintenance services using a hybrid DMAIC six sigma which then improved the quality of analysis using brainstorming and decision making on the best vendors using AHP. The hybrid of six sigma is very instrumental in reducing the weakness of six sigma which forces the process of monitoring diligently and continuously. This research yielded better service quality compared to the current system for maintenance ICT at the Indonesian Constitutional Court.

“…Six sigma is now a widely used and well accepted method which can eliminate root causes of the unwanted variations and provides good control of the process. The main focus of six-sigma is on process control, continuous improvement, customer needs, statistical analysis and business growth [2][3][4][5][6]. Most widely used approach of the six sigma is DMAIC cycle i-e Define, Measure, Analyse, Improve and Control is a five-step six-sigma improvement model adopted by manufacturing and service organisations to improve their current capacities of existing processes [7][8][9][10][11][12].…”

All over the world six sigma is being adopted as a quality improvement approach towards zero defects. Unfortunately, the adoption of the six sigma methodology in manufacturing companies is very rare in developing countries due to different challenges and Pakistan is standing in the same row. This article demonstrates the practical use of various six sigma tools throughout Define, Measure, Analyze, Improve and Control (DMAIC) cycle by conducting a case study of manufacturing company in Pakistan. The potential problem was the external leakage defect in refrigerator during its production. The goal of this project was to identify critical root causes of external leakage and eliminate them with the help of six sigma DMAIC methodology. Project charter, Pie chart, Bar chart of faults, Suppliers Input Process Output (SIPOC), Voice of Customer (VOC) and flow process map were used to define the problem, its scope and process routing. Pareto chart was used to identify sub defects and sigma level was calculated for the existing process. Feed rate, capillary action of filler material, cleanliness, visual inspection and unsuitable heat input were the major causes of external leakage, identified by cause and effect diagram. Cause and effect matrix was developed to rank the identified causes. Further, DoE was performed to improve the process by conducting different alterations in the parameters. In order to control the process, FMEA sheet was prepared to sustain the process improvements. The FMEA control plan needed to be revised at specific time intervals to attain continuous process improvement. External leakage defect was reduced by 30% and service call rate (SCR) was improved with lower complaints from customers.
