Impact of the implementation of the Lean Six Sigma process within Moroccan environmental SMEs

Lean Six Sigma is a management approach used to improve the efficiency, quality and performance of processes within companies. When applied to environmental businesses in Morocco, Lean Six Sigma can bring several significant benefits. Lean Six Sigma aims to eliminate waste, inefficiencies and non-essential processes. By applying it to Moroccan environmental companies, it is possible to optimize operations, improve productivity and reduce costs. That can contribute to more efficient use of resources and better management of projects. Environmental companies have the primary mission of minimizing their impact on the environment. Applying Lean Six Sigma can help identify sources of pollution, reduce waste, improve energy efficiency and promote sustainable practices. That helps build their environmental credibility and meet stakeholder expectations. Lean Six Sigma emphasizes customer satisfaction and product or service quality. By integrating this approach, Moroccan environmental companies can improve their production processes, eliminate defects and errors, and provide better quality products and services to their customers. That can promote customer loyalty and increase their competitiveness in the market. The application of Lean Six Sigma within environmental companies in Morocco can bring significant benefits, such as improved operational efficiency, reduction of environmental impacts, improving the quality of products and services, strengthening the culture of continuous improvement and developing employee skills. This is the case that we have dealt with in This article in order to measure the Impact of the implementation of the Lean Six Sigma process within Moroccan environmental SMEs. By adopting That approach, Moroccan environmental companies can strengthen their competitiveness, environmental sustainability and ability to meet stakeholder expectations

Shainin methodology: An alternative or an effective complement to Six Sigma?

Purpose: The purpose of this paper is to provide a brief overview of Six Sigma and Shainin RedX (R) methodology and to propose the modification of Six Sigma methodology in order to achieve the improved efficiency of DMAIC in the diagnostic journey using some of the approaches of Shainin RedX (R) methodology. Methodology/Approach: The diagnostic journey of Six Sigma has been revised by bringing key elements of Shainin RedX (R) methodology into DMAIC: task domain character of the method, focus on the dominant root-cause, use of the progressive elimination method and the application of a problem-solving strategy. Findings: This paper presents a proposal of DMAIC framework modification using selected tools and procedures of Shainin RedX (R) methodology in the diagnostic phase. Research Limitation/implication: Although the improved methodology is used in the environment of the automotive supplier, in this paper, practical examples are not included in order not to violate the licensing rules applied by Shainin LLC. Originality/Value of paper: The contribution of this article is the proposal of modified methodology, which should improve the effectiveness of problem-solving.Web of Science192311

Analisis Pengendalian Kualitas pada Produk Batang Rokok Sigaret Kretek Mesin (SKM) Menggunakan Metode Six Sigma dengan Pendekatan DMAIC di PT. XYZ

This study aims to determine the causes of defects in Kretek cigarettes at PT. XYZ, and how to minimize defects in Kretek cigarettes using the DMAIC approach at PT. XYZ. Data analysis was performed using the six sigma concept, which includes DMAIC. The research results are (1) the causes of defects or defects consist of 4 factors: humans, methods, materials, and the environment. The human factor is that operators leave the machine during production fatigue and lack concentration. The method factor is not checking raw materials and the lack of instructions. Material factors include raw materials or materials of poor quality with the category of non-sticky glue and dislodged filters, and for environmental factors, there is engine noise and ambient temperature. (2) The results of the analysis of the DPMO Sigma Quality Level and Process Capability values for cigarette stick products with an attribute defect in the form of non-sticky glue produce an average DPMO value of 550716.8432 with a sigma level of 1.38. In contrast, the attribute defect in the form of Dislodged Filters produces an average DPMO value of 234511.2977 with a sigma level of 2.23. These results are categorized as low process capability, so their performance needs to be improved. Thus, recommendations for appropriate corrective actions are given, namely by providing training and training to workers. They offer directions in strengthening SOPs for checking raw materials, improving the quality standards of raw materials received, and equipping workers with equipment such as masks and ear plugs as well as higher concentrations during the production process so that defects can be minimized

The properties of the three-nucleon system with the dressed-bag model for nn interaction. I: New scalar three-body force

A multi-component formalism is developed to describe three-body systems with nonstatic pairwise interactions and non-nucleonic degrees of freedom. The dressed-bag model for $NN$ interaction based on the formation of an intermediate six-quark bag dressed by a $\sigma$-field is applied to the $3N$ system, where it results in a new three-body force between the six-quark bag and a third nucleon. Concise variational calculations of $3N$ bound states are carried out in the dressed-bag model including the new three-body force. It is shown that this three-body force gives at least half the $3N$ total binding energy, while the weight of non-nucleonic components in the $^3$H and $^3$He wavefunctions can exceed 10%. The new force model provides a very good description of $3N$ bound states with a reasonable magnitude of the $\sigma NN$ coupling constant. The model can serve as a natural bridge between dynamical description of few-nucleon systems and the very successful Walecka approach to heavy nuclei and nuclear matter.Comment: 26 pages, Latex, 7 figure

Challenges and success factors for implementation of lean manufacturing in European SMES

Small and medium-sized enterprises are crucial to value creation in the European economy. The SMEs need continuous improvement initiatives to stay competitive. However, SMEs are less likely to implement lean practices compared to larger companies. Limited research exists on the factors that are vital for succeeding with Lean implementations in SMEs. A case study of Norwegian and Belgium SMEs has been conducted in the European research project ERIP (European Regions for Innovative Productivity). Six critical success factors are suggested, which correspond well with previous research: 1) Ensure strong management involvement. 2) Develop thorough employee participation. 3) Allocate sufficient time for preparing the organisation. 4) Focus on creating motivation to complete initiatives. 5) Build competence internally in the organisation. 6) Establish a performance evaluation system

Tools to measure the technological capabilities of the aerospace industry

Purpose: The following article describes steps along with a mathematical model to determine the technological capability of the aerospace industry of Mexicali in the area of design (ICTD) and manufacturing (ICTM). Design/methodology/approach: This model was performed by weighted variables using factor analysis to identify technological capacities of Small and medium-sized enterprises (SMEs) and compare them with those that must be accomplish to become suppliers for transnational industry (TNCs). Findings: The results suggest that SMEs must realize a comparative table QFD of their current capabilities and the requirements established by transnational corporations, to create a strategic plan that includes; certifications (AS 9000, NAP CAP, Belts, ISO, Six Sigma), software acquisition and updated equipment necessary for reducing the technological gap. Additionally, it is recommended the integration of clusters of enterprises SMEs for the strengthening of technological capacities. Originality/value: Up to we know, there is not similar model for measuring technological capabilities of aerospace industry.Peer Reviewe
