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...

This paper first enlists the generic problems of alloy wheel machining and subsequently details on the process improvement of the identified critical-to-quality machining characteristic of A356 aluminum alloy wheel machining process. The causal factors are traced using the Ishikawa diagram and prioritization of corrective actions is done through process failure modes and effects analysis. Proce...

The fast changing economic conditions such as global competition, declining profit margin, customer demand for high quality product, product variety and reduced lead– time etc. had a major impact on manufacturing industries. To respond to these needs various industrial engineering and quality management strategies such as ISO 9000, Total Quality Management, Kaizen, Just–in–time manufacturing, E...

The objective of this paper is to optimize sales lifecycle performance at United Biosource Corporation through the Six Sigma DMAIC methodology to produce fact based, and data driven approaches with reduced process inconsistency. This methodology was applied to identify inefficiencies within the current sales lifecycle process, including excessive data collection and workflow activities. Evaluat...

Six Sigma Methodology which was developed in 1980`s at Motorola (USA) has recently caught up with time in improving quality in large and as well as medium sized industries. Here, we are talking about the concept of six sigma & its implications in several fields. After going through the paper the reader will become fully aware of six sigma methodology as to how it optimizes the manufacturing wit...
