... Over time, publications on the combination of both concepts began to appear (Shafer & Moeller, 2012;Swink & Jacobs, 2012) and the concept of Lean Six Sigma (LSS) emerged. Moreover, attempts to effectively combine them by using their positive features took place in various enterprises (Anchanga, 2006;Muzaffer et al., 2016;Sharma, 2003;Thomas et al., 2009), and the conducted research showed positive economic effects in various countries (Bożek & Hamrol, 2012) and various sectors of the economy -e.g. in services (Schnellbach & Reinharta, 2015;Urban, 2016). ...
Motivation: For a long time, new strategies, concepts and solutions regarding both process management in enterprises and managing the supply chains have been presented in the literature and implemented in business practice. They are to be an alternative to existing concepts. Considerations regarding these concepts focus on the speed of adaptation to changing conditions in the environment, flexibility, diversification and reducing the risk of disruption. The justification for the implementation of new solutions are the conditions and challenges in the environment of enterprises, especially the Covid-19 pandemic, but also economic crises, wars, terrorism, natural disasters, changes in energy prices. An example of such a concept is the Agile strategy. According to some authors, this strategy is a competitive concept to Lean Management. Other authors believe that they are complementary and that there are opportunities to combine them and thus achieve a synergy effect.Aim: The aim of the article is to compare the effectiveness of Lean and Agile process and supply chain management strategies in conditions of environmental instability, based on literature review and own research.Results: Lean and Agile strategies can be combined to some extent. In addition, such a combination may prove to be more effective and more resistant to interference than using “clean” strategies. The result of proper application of both strategies are lower costs, better product quality, higher level of logistics service, greater customer satisfaction and employee involvement, and thus the trade-up effect.

Concept of Six Sigma is comprehensive for finding the appropriate strategy as of the industry can run as efficiently as possible and survive in an economic wave currently under challenging times, including the tourism industry, which is the object of this research. These papers examine an overview of the empirical study of relationships between six sigma strategies toward tourism industry performance. For many countries, tourism is seen as one of the instruments for developing country because it can trigger new economic activities. Tourism also has assertive economic impact on the balance of payments, unemployment, GDP, and profitability. Unplanned and uncontrolled tourism growth has an impact on financial sustainability. The methodology used in this research is quantitative by distributing an online questionnaire consisting of 16 statement items with a five-point Likert scale. The sample size used for this research is 300 tourism service providers in 10 of the city in Indonesia, which is the leading destination for tourists. This research was processed using smart PLS 3.2.9 analysis tools and methods research in this study using Structural Equation Modeling (SEM), namely the equation model with a variance-based approach or modeling component-based structural equations. The findings from this study indicate that the latent variable models are involvement and top management commitment, training and education, cultural change, industrial infrastructure, and teamwork has a fit outer model relationship (> 0.7) between latent variables and indicators of efficacious Six Sigma implementation in the tourism industry in Indonesia. However, top management commitment and industrial infrastructure have a low t value, so of course, this is a challenge and input for developing the tourism industry in Indonesia in the future.

Investments in innovation and quality management systems have long been presented as tools that can boost organizational performance. In Brazil, empirical, systematic, and rigorous research on such relations on such relations is still scarce. Given this context, this study sought to verify, using multiple linear regressions, how investments in innovation, and adoption of the six sigma methodology and ISO 9001 certification, impacted the financial performance, in terms of profitability, of the 101 Brazilian publicly traded companies comprising the study sample in fiscal year 2019. Regression results shows evidence that Brazilian publicly traded companies are having little success in regards to financial results by their six sigma efforts, and that R&D efforts and ISO 9001 certification exert positive and significant impact on profitability, via the ROA index. The interaction between ISO 9001 and R&D came close to significance, indicating a possible synergistic effect to be tested in future studies. Besides contributions to the entrepreneurial field, aiding companies to direct their efforts toward initiatives capable of positively impacting profitability, such findings also help advance academic knowledge.

... Basically, it is one of the recent continuous improvement approaches applied in the best-in-class companies. The application of Six Sigma is increasing and expanding from manufacturing into all company activities, including services, transactions, administration, research and development, sales and marketing, and notably into the customer-direct sectors (Ertürk et al., 2016). ...
Six Sigma is a realistic approach to enhancing a business's performance by reducing the variability of the process outcomes. The techniques of Six Sigma involve the application of the DMAIC phases to existing processes to improve them. However, there is a reticence and fear of implementing the DMAIC method. This is true, especially in the case of small and medium-sized businesses. To fulfil this gap, the paper targets at collecting data and forming a comprehensive, fitted framework to support the implementation of Six Sigma method within SMEs, relying on a documentary research approach, using an adapted interview, a model, and many practical cases. The Framework has valorized the all Six Sigma journey in SMEs and was tested and validated separately through practical studies and by proponents from leading practitioners and specialists.
... The literature reflects the wide use of SS and the impact it has on businesses. According to Ertürka, Tuerdi and Wujiabudula [6], SS has the potential to improve the competitive advantage of an organisation; and a further conclusion from an empirical study was that the application of SS resulted in an increase in organisational performance. Gupta and Schultz [7] suggested that it is advisable for small of SS implementation and the training costs to make SS work. ...
... The adoption of SS helps businesses to gain financial benefits and improve their productivity and customer satisfaction [1]. Several researchers identified a common benefit of an increase in the bottom line in companies that successfully implemented SS [6,11,[15][16]. Some researchers have also agreed, on the basis of research findings, that SS has had a positive impact in the service industry [17][18][19][20]. Anthony [1] identified the potential benefits to be effective decision-making by management owing to the availability of data and facts, a reduction in misdirected problem-solving efforts and costs, a better understanding of the needs and expectations of customers, and efficient and reliable internal operations, leading to a greater market share and satisfied shareholders. ...
The quest to improve customer satisfaction is one of the core aims of businesses in the competitive global market. This paper aims to apply the principles of Lean Six Sigma for continuous improvement in a small enterprise in the service industry in South Africa. A case study approach was used to carry out the investigation using the Lean Six Sigma ‘define measure analyze improve and control’ (DMAIC) approach. Data collection was done in a face-to-face interview and brainstorming session with the business owner and consultants. Observations and a time study were also used to collect additional data. The results showed a lack of knowledge and awareness of Lean Six Sigma among the business owner and the consultants. The commitment to and engagement of management in the project contributed positively to the implementation of the DMAIC approach. The process improvement changes were applied over a period of three months, after which the process performance was reviewed. The case study resulted in a 60.3% reduction in total non-value-added time and an increase in both the value-added time (53.85%) and the amount of uptime (10.74%). Furthermore, downtime was also reduced (47.7%). This study shows that the application of the Lean Six Sigma tool could solve the challenges of productivity and waste in a bookkeeping and tax consulting SME in the Gauteng province with a direct implication for operational efficiency and customers’ satisfaction.

... Other approaches to a successful management system exist. However, the introduction of the Six Sigma method in the 1980s resulted in significant improvements, especially in the areas of reliability, service quality, and overall management (Ertürk, Tuerdi, & Wujiabudula, 2016). Six Sigma was initially used to improve industrial operations Currently, Six Sigma is use to improve marketing, purchasing, billing, invoicing, insurance, human resource and customer, the Six Sigma approach is also being used in call answering functions with the goal of constantly reducing defects throughout the organization's processes (Patil & Inamder, 2014). ...
A r t i c l e i n f o The goals of this research were to identify problems, find solutions and implement DMAIC to improve the high defect rate in the weaving process that was causing high operation cost at a wire harness tape manufacturing in Thailand. In this study, qualitative research was used with samples collected, and the paper gives an insight into the 16-week journey of applying a DMAIC (Define-Measure-Analyze-Improve-Control) of Six Sigma framework to achieve reducing defects in the weaving process. The study utilized the Six Sigma tools such as brainstorming, SIPOC, affinity diagram, Isikawa diagram, Pareto chart and checklists. As a result, the root cause of significant defects were first, the human problem was defined, human error, no motivation, not enough training. Then an improvement plan was constructed, that included training of SOP, ISO 9001:2015, and CTQs. Next, the problem with machines were defined such as machines were not in the appropriate condition causing them to breakdown and shortages of spare parts to fix the machines. Implementing the preventive maintenance, daily checking, and monthly scheduled maintenance will stop these issues from occurring. Last, the raw material issue, which lacked full inspection, lack of vendor site inspection, and lack of qualified products, the issues can be prevented by implementing a system of value chain management and supplier relationship management with vendor site inspection planning. The ISO 9001:2015 is the significant tool implemented to ensure the company meets quality control and quality assurance. In the end, the desired achievement to reduce 6% to zero defect rate was achieved. The value of this study presents an industrial case that demonstrates how the deployment of Six Sigma and DMAIC can assist manufacturing productivity to achieve quality improvements in their processes.
