“…Previous studies have shown that both 8D (Riesenberger & Sousa, 2010;Kaplík et al, 2013) and Six Sigma (Swarnakar, Vinodh & Antony, 2016;Ghosh & Rao, 1996) were highly effective in identifying the root cause of the problem and developing a permanent corrective action accordingly. Generally, 8D is used for less complex problems with quick response time, and Six Sigma -for more complex issues.…”

The current research study aimed to explore the utility of selected problem-solving tools and techniques in root-cause analysis to demonstrate their practical application. An experimental research design adopting a positivist empirical approach with a deductive strategy was followed to assess the effectiveness of a combined (8D & Six Sigma) problem-solving approach in reducing a high defects rate of a mixer shower assembly line. A novel application of the 8D framework in combination with Six Sigma and other analytical tools was found highly effective in reducing the reject rate from 11.84% to 0.11%. Successful identification of the root cause led to the implementation of permanent corrective action ensuring a long-term stable assembly process. The research study provided a problem-solving framework that was found effective in resolving a complex problem and implementing long-term corrective action in an assembly production line. However, this framework can be used in other industries. The research study provides a solution to a high number of leak rejects in a sub-assembly where "O-seals" are used between mating parts. It also provides analytical tools that were found highly effective during the problem-solving process.

“…To address these issues, manufacturers must improve the effectiveness and efficiency of their solutions and production processes through quality assurance efforts using the Lean Six Sigma framework based on the DMAIC (Define, Measure, Analyze, Improve, and Control) process and the PDCA cycle of the ISO 9001:2015 and the Lean 8D method [6][7][8][9][10]. The 8D methodology, also known as the Ford TOPS 8D, was first developed and implemented by Ford Motor in the 1980s Click or tap here to enter text.and has been widely adopted in the automotive industry for problem-solving [11][12][13]. It is still used by many companies.…”

Customer satisfaction is critical for the success of any organization. This case study presents a design company and manufacturing supplier that has received customer complaints about defective temperature sensors and power supply units in maritime vessels. The research aims to identify the root cause of the issue and implement a solution to prevent its recurrence using the Lean Eight Disciplines methodology. This includes: (1) a 5 Whys analysis by a cross-functional team, (2) confirmation of the problem description, (3) containment actions, ( 4) root cause analysis of the occurrence, ( 5) permanent corrective actions, ( 6) implementation of the permanent corrective action, ( 7) actions to prevent recurrence, and ( 8) closure with an 8D report and congratulations to the cross-functional team from the design, engineering, and supplier production sites.This study presents the development and implementation of the Eight Disciplines (8D) investigation tool for addressing issues in the factories and improving the product life cycle in the manufacturing industry. The 8D tool is designed for the cross-functional teams to work together to identify the root cause of problems using the "five whys" method and implement corrective and preventive actions to prevent similar issues from occurring in the future. The novelty of this case study is the development of an 8D analytics template for product managers and practitioners in manufacturing and production companies to use for improving the quality of products throughout their life cycle. The case study also highlights the challenges and opportunities of using the 8D tool for problem-solving, including the high warranty cost and production failures, the unreliability of products and resources, and different scopes of issues. In one example, the 8D analytics template was used to identify a long-term fix for a circuit prone to leakage current by using a different flux chemistry that can be cleaned with a water-based solvent, rather than the traditional "no-clean" solder flux that requires specific solvents for effective cleaning.

“…Manufacturing companies operating in the present conditions are forced to constantly improve their production processes and ensure the quality level of products in line with customer expectations. Many methods and quality management tools are used to carry out the cause-and-effect analysis, including: Ishikawa diagram (more on Ishikawa diagram see [13,14,18]), 8D method (more on 8D method see [12,22,23]) or FMEA analysis.…”

The paper presents the definitions of the term quality quoted in the literature on the subject. FMEA (Failure Mode and Effects Analysis) methodology was presented. A reloading ramp was characterized as the subject of the study. A cause-and-effect analysis of non-compliance in the finished product was performed using the Pareto-Lorenz diagram, Ishikawa diagram and brainstorming. The FMEA analysis of the assembly table indicated the elements of the workstation causing the most frequently occurring non-conformities. Based on the obtained results, corrective actions were proposed to reorganize the assembly station. The implemented activities made it possible to reduce the critical RPN coefficients for the elements of the assembly table and to shorten the time necessary to make one piece of the finished product.
