The present paper discusses the results of a research project going on at Politecnico di Milano, aiming at analysing the idiosyncrasies of Six Sigma implementations in Italian companies. In particular, the project addresses the following research questions, regarding the approach of Italian companies towards Six Sigma: are Italian companies implementing Six Sigma exactly as it was originally co...

Abstract Quality control is a strategy to measure the ability of production process. In addition, it can identify factors that cause non-standardized products. Currently, crab products packaged in cans are great demand by foreign countries. One companies produce these PT Sumber Mina Bahari. Indonesia, many process for export buyers. For this reason, quality needed so product compete with other ...

The Decision On Belief (DOB) control chart is a univariate that was initially introduced as solution to the problem of less than optimal limits from shewhart attribute diagram, especially C. new scheme based on DOB calculation step , can change data which not normally distributed into normal distribution, then diagnose quality process errors. . defines belief or an assumption in observation vec...

There has been considerable number of papers published related to Six Sigma applications in manufacturing and service organizations. However, very few studies are done on reviewing the literature of Six Sigma in all the areas including manufacturing, construction, education, financial service, BPOs and healthcare etc. Considering the contribution of Six Sigma in recent time, a more comprehens...

This research examines the application of the Six Sigma methodology to a business problem that emerges with an information technology (IT) solution as the best alternative. A Time/Leave Reporting Process, which supports the payroll function, is investigated using Six Sigma methodology. This case application serves to demonstrate the Six Sigma approach to business process problem solving. One ad...

Purpose-The purpose of this paper is to propose a robust ‘observation’ procedure drawn from the social science research literature for adoption in a Lean Six Sigma project setting. A case study illustrates the application of the proposed observation procedure in a Lean Six Sigma project undertaken in a European airport to improve process speed and reduce variability. Design/methodology/approach...

Six sigma is new to construction sector and this philosophy is to reduce the defects in the construction. The aim of this study is to evaluate Six Sigma as a process improvement method within construction sector. In order to improve the process in construction it is important to understand the factors affecting the construction process and analyze the factors for the construction improvement. I...

Affinity Diagram – A tool used to organize and present large amounts of data (ideas, issues, solutions, problems) into logical categories based on user perceived relationships and conceptual frame working. Often used in the form of “sticky notes” sent up to the front of the room in brainstorming exercises, and then grouped by facilitator and workers. Final diagram shows relationship between the...
