This work describes a strategy to reduce the cost associated with poor quality, by reducing the parts per million defects by Defining, Measuring, Analyzing, Implementing and Controlling (DMAIC) the production process. The method uses a combination of principles of Six Sigma applications, Lean Manufacturing and Shanin Strategy. The process has been used in analyzing the manufacturing lines of a brake lever at a Connecticut automotive components manufacturing company for reducing the cost associated with the production of nonconforming parts. The analysis was carried out with the help of the data collected on nonconformance parts and the application of phase change rules from DMAIC (+). Data analysis was carried out on statistical process control softwares, MINITAB and SPC XL 2000. Although, the problem of tight bushing existed on only one line of the brake lever assembly, this problem solving approach has solved the tight bushing problems on all assembly and alternates lines in a time- and cost-effective way.

CV Marga Jaya (Pabrik II) adalah perusahaan yang bergerak di bidang pembuatan paving/conblock secara masal. CV Marga Jaya (Pabrik II) selalu berusaha mengurangi pemborosan yang terjadi selama proses produksi paving/conblock. Pemborosan yang terjadi antari lain, adanya produksi berlebih, transportasi, waktu menunggu, dan cacat yang berlebih.  Lean Manufacaturing merupakan pendekatan yang bertujuan untuk merampingkan proses dengan mengurangi pemborosan yang terjadi selama proses produksi. Pendekatan konsep lean manufacturing dimulai dengan membuat big picture mapping, dilanjutkan dengan waste assessment model (WAM), diagram cause and effects, value stream analysis tools (VALSAT), usulan perbaikan waste yang terjadi, dan pembuatan descrete event simulation (DES). Hasil yang didapat bahwa waktu menunggu yang terjadi diperbaiki dengan menggunakan conveyor, produksi berlebih yang terjadi diperbaiki dengan melakukan perencanaan produksi, dan cacat berlebih yang terjadi diperbaiki dengan menggunakan 5W+1H dengan sebelumnya menggunakan konsep lean six sigma dan didapat nilai sigma sebesar 4,31 sigma. Simulasi proses menunjukkan dengan mengurangi pemborosan, kemampuan produksi naik 15,36% (penjemuran 30 hari) dan 147,20% (penjemuran 7 hari).

At the global level, the service industry represents a critical component for the economy and its growth trend is above of the other sectors. This sector alone is responsible for 63% of the gross domestic product and 45.5% of labor occupation worldwide. Despite its role in modern economies, the sector receives very little attention. In the literature, the authors have found the efforts that have been made to increase the efficiency and productivity of this type of organizations: adapting philosophies, tools, and/or techniques that were born to achieve this goal in the manufacturing industry, such as Lean manufacturing, total quality management, six sigma, lean six sigma, among others. The objective of this study is to perform an exhaustive literature review of the critical success factors reported in diverse studies of the implementation of these tools or philosophies in the service sector, as well as their differences, similarities, and results.

Lean Six Sigma is a management focused on quality and productive performance in operating systems. This article discusses the foundations of this methodology through of two different conceptions of management, Lean Manufacturing and Six Sigma. First of the article explain the DMAIC (define measure, analyze, improve and control) and their respective phases, after the Lean philosophy with the sipoc and value stream mapping techniques. The article aims to show integration of these two conception and their results. The methodology consisted in a theory was based on a literature search an exploratory research which consisted of three case studies in differences companies located in Sorocaba, São Paulo. In this article studies the applying of Lean Six Sigma and its results.

This article examines the implementation of continuous improvement patterns and the various continuous improvement (CI) models used in an organization. Despite the size of an organization, the goal is to achieve the maximum profit by pursuing continuous improvement. There are certain models and theories used in organizations for this reason, which include total quality management, business process re-engineering, Six Sigma, and Lean manufacturing methodology. These models are not only concerned with customer retention and profit maximization, but they are also equally effective for the employee's wellbeing. Different methodologies used in continuous improvement processes will help industrial engineers simplify complex tasks by applying CI tools to different situations. However, the key is to understand what tools and models are appropriate for each application.
