In this paper, we survey Six Sigma in Korea company real fields. Six Sigma itself are developed depend on each company culture and strategy. Our country has been more than 10 years since introduced Six Sigma in our country. Each company which work six Sigma are developed differ way depending on his company situation. Our country Six Sigma in our country is necessary to survey and analysis. Firstly, we survey how to use Six Sigma. Next, we survey to find success factor and failure factor by reports published by company and papers by published in journals.

Many 6‐sigma innovation companies are obtaining ISO9000 series or ISO/TS16949 certifications. However, not many of them have considered the integrated management of ISO/ TS16949 at the time of 6‐sigma introduction. ISO/TS16949 focuses on the process of an overall company. In particular, APQP (Advanced Product Quality Planning) requires that from the beginning all the planning should have a clear quality planning business process. Each company can decide the best course of action to suit its individual needs. Lean DFSS in 6‐sigma offers the concrete development steps of the product development process. And if analyses of Input, Output, Target, Process, KSF, KPI, and FMEA is done in each process and clearly defined in APQP, mutual organic and effective systems can be initially achieved.

To deal with the present situation and recover after the COVID-19 pandemic, construction firms are required to recognise the trends in construction supply chain management (CSCM) for the upcoming years and determine the appropriate practices towards the trends for the improvement of construction activities in terms of strategy, tactic and operations. This paper aims to recognise key trends in CSCM and uses these trends as strategic criteria for the evaluation and prioritisation of lean construction (LC) tools at different project phases including design and architectural engineering, planning and control, on-site construction and safety management.

The integrated analytic hierarchy process–Delphi method is used to collect and analyse the data from construction experts to evaluate the importance levels of the CSCM trends and recommend the appropriate tools for LC practices to improve project performances.

Seven key CSCM trends are identified: lean supply chain management (SCM), supply chain (SC) integration, SC standardisation, SC problem-solving, SC information-sharing, SC flexibility and SC sustainability. Based on these trends, a set of prioritised lean tools are suggested for LC practices, in which “virtual design construction” (VDC) and “last planner system” are considered as the central tools. These two LC practices can be integrated with other effective tools to support the strategic, tactical and operational targets in construction supply chain (CSC) projects.

This study gives the managerial implications by developing an application framework of LC practices for CSC projects. The framework promotes “VDC” as a strategic tool for the phase of design and architectural engineering and considers “last planner system” as the central LC practice for the phase of project planning and control. The framework also focuses on the improvement of efficiency in construction operations by taking into account the aspects of on-site collaboration, problem-solving, improvement and safety.

Up to date, there is still a lack of researches in classifying and prioritising the significant LC tools for each project phase to deal with CSC issues in both breadth and depth. Thus, this study is performed to provide construction managers with the awareness of CSCM trends on which they can focus to have strategic criteria for selecting LC practices to improve CSC performances.

The purpose of this study is to present the academic pattern of project-based studies on the Lean Six Sigma (LSS) approach in a comparative manner in the context of Turkey.

Focusing on the context of Turkey, a detailed search was conducted at the National Thesis Center of Turkey, and on Google Scholar between November 28 and December 15, 2021, using the keywords “Lean Six Sigma” and “Lean 6 Sigma” in both Turkish and English. As a result of this search, no conference proceedings on the subject were found. However, 25 postgraduate theses and 19 articles were accessed. It was determined that ten of the 19 articles were produced from these theses. It was observed that nine of the 25 postgraduate theses contained conceptual analyses. At this point, it was concluded that the project-based theses conducted in the context of Turkey provided the necessary representation on the subject. Therefore, the 16 postgraduate theses that had been accessed constituted the sample of the study. These 16 theses were subjected to a comprehensive evaluation with the systematic analysis design, with descriptive content analysis being used as the data analysis tool of the research. In this context, the theses were examined using parameters such as type, number, year, university, institute, department, discipline, original language and title of advisor. Other parameters used were purpose, industry, duration, team, results, tools and techniques of the LSS projects mentioned in the theses.

It was determined that the number of postgraduate theses on LSS was low in number, with only one study having been performed at the doctoral level, and most studies having been produced in 2019. In addition, it was observed that the subject had been studied by different universities, institutes, disciplines and departments with the LSS spreading to different academic disciplines. Most of the relevant theses were written in Turkish, and it has been determined that these theses were mostly carried out under the supervision of academicians with the title of assistant professor. It was also found that the purposes of the theses, the tools used throughout the process and the results obtained were per the LSS spirit. On the other hand, it was determined that the duration of the project and the composition of the team members would vary due to the diversity of features that make the internal dynamics of the projects clear.

The research revealed the academic pattern of the project-based studies on the LSS in the Turkish context. The use of systematic review design and descriptive content analysis as data analysis tools in the research is an important initiative. While the uniqueness of the studies carried out on such a practical subject cannot be discussed, the holistic approach of these studies increases the contribution value of the research. At this point, this study is considered to be especially valuable for an understanding of LSS research in country-specific conditions. In this aspect, it is an aim of the aforementioned research to become a resource for researchers and practitioners interested in LSS, with this research providing a basis for making contextual comparisons in the future.

A comprehensive approach to quality goal setting is presented that is consistent with Motorola's six‐sigma metric development. In particular, process mean shifts are determined and incorporated into the goal setting process. Methodology includes basic probability theory, statistical control charts, and capability indices. Data for an aircraft part consisting of hundreds of laser‐drilled holes are used to illustrate the procedures. As a result of applying the methods, quality goals are customized based on the number of opportunities for defect, the target end‐product quality level, and the mean shift shown to exist for the processes involved in the product's manufacture. The methods described overcome the mistakes implicit in blindly conforming to the standard six‐sigma goal of 3.4 defects per million.

First impressions are not always everything but they do count significantly in many business contexts. If not, then why would most retailers invest so much energy to make their shop windows appear as attractive as possible? Online companies face a similar challenge to entice the customer. Only in their case for shop window read website. Since it is the primary communication channel between online traders and their current and potential customer base, a high quality site is imperative. To strike the right chord with site visitors, companies need to focus closely on key aspects relating to content and design. The overall objective should be to make the website accessible, easy to use, interesting and fast.

Companies implementing total quality management initiatives need to ensure its full integration across the entire organization. In‐depth training can inform employees and prepare suitable candidates for project leadership and other key roles. Practitioners should adopt a systematic approach to risk assessment. Close monitoring of events impacting across the whole value chain can enable critical early detection of impending threats.

Provides strategic insights and practical thinking that can have a broader social impact.

The aim of the research is to use an integrated approach – simulation and Six Sigma to improve the ambient air quality.

Integration of simulation and Six Sigma DMAIC methodology in a foundry had been used to improve the ambient air quality. Various elements of the Six Sigma toolkit such as Cause and Effect diagrams and Failure Mode and Effect Analysis have been used to discover the root causes underlying the problem and prioritize action and incorporate cost‐effective solutions. Simulation has been used to improve and control the environmental efficiency by monitoring the performance of the Venturi Scrubber – the pollution control equipment, by running the model under varying conditions.

The integrated application of Six Sigma and simulation has been successful in reducing particulate emissions from 200 milligrams per cubic meter to less than 20 milligrams per cubic meter and sulphur dioxide emissions from 45 milligrams per cubic meter to less than 4.5 milligrams per cubic meter, thus reducing air pollution.

Air pollution is a burning problem in the present scenario and foundry industries are one of the contributors to air quality degradation. The approach described in this paper is a step towards reducing air pollution due to foundry operations.

Integration of Six Sigma DMAIC methodology and simulation provides a novel cost‐effective strategy for monitoring and reducing air pollution resulting from foundry operations. This paper is useful for environmental division of foundry and other manufacturing industries.
