“…Avunduk (2019) performed a process improvement on the pet blow molding machine using the Lean Six Sigma method. This work and financial gain contributed to the company's long-term environmental sustainability goal and the vision of a more livable world with less energy consumption [6]. Sevgili and Antmen (2019) aimed at lean production by using value stream mapping in a metal processing factory and minimized intermediate stocks due to process improvement, shortened the production flow time, and increased the daily production amount [7].…”

Today, motorsports is one of the sports branches with the world's largest audience and fan base. The production techniques of the tires used in these organizations are an indispensable factor in order to be the pioneer of the sector. In this study, SWOT Analysis and Failure Modes and Effects Analysis were performed for two different production lines, and the superiority of the lines against each other was evaluated. The process to be improved on the excellent line was determined as a result of brainstorming by an expert team. After the changed parameters, the effects on the final product and the process were evaluated. The study was concluded by determining that all the changes made do not constitute an obstacle to the continuity of the process and the quality of the final product. Time analysis was made by video recording the process whose cycle time changed. As a result of the calculations made after the time analysis, the annual tire gain was calculated as 7299.

“…Moreover, the researcher observed that LSS is also used in critical issues such as the development of data-based process management systems. Avunduk (2019) performed a process improvement application by following the DMAIC stages in a study in which a company operating in the beverage bottling industry applied LSS techniques to reduce energy use in its production processes. Within the scope of this particular study, the maximum energy consumption point was determined by analyzing energy usage, and due to the project-oriented nature of LSS, the entire application was performed on the PET bottling process, which consumes the most energy.…”

Purpose 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. Design/methodology/approach 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. Findings 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. Originality/value 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.

Plastik ürünlerin imalat sürecinde kullanılan yaygın yöntemlerden biri de enjeksiyonla kalıplama yöntemidir. Enjeksiyonla kalıplama sürecinde aralarında karmaşık ilişkiler bulunan parametrelerle birçok performans göstergesinin olması, süreci daha karmaşık hale getirmekte ve son ürünlerin kalitesini büyük oranda etkilemektedir. Endüstride ortaya çıkan sorunların çözümü için görünür nedenlerinden çok kök nedenlerine ulaşılması, doğrudan üretim kalitesini ve rekabet gücünü etkilemektedir. Genel hataların belirlenmesi ile hataların zamanında önlenerek sonraki üretim süreçlerine yansıması engellenebilir. Bu nedenle üretim süreçlerinde makinelerde planlı bakım sürecinin oluşturulmasının yanında, proses kontrolü ve optimizasyon tekniklerine de gereksinim vardır. Bu çalışmada, pet şişe üretim endüstrisinde meydana gelen hatalı ürünlerin sayısının azaltılması amacıyla çözüm teknikleri geliştirilmiş ve üretim hattına uygulanmıştır. Üretim hattında yapılan düzenlemeler sonrasında, hatalı ürün oluşumunda ve iade miktarında iyileşme sağlanmıştır. Bu yaklaşım ile karmaşık endüstriyel üretim ortamının esnek olarak yönetilebilmesi için hataların süreç içinde belirlenerek üretimden kaynaklı sorunların azaltılabileceği öngörülmektedir. Ayrıca işletmelerin üretim maliyetlerinde elde edilecek önemli azalmalarla rekabet gücünün de artacağı düşünülmektedir.
