Implementation of Lean Six Sigma to Improve Cement Production Process

Concrete is the most widely used building material nowadays. Its properties greatly depend on the proportions and properties of its constituents. Cement is the major component of concrete. In 2011, the global cement market size was about 237.15 billion U.S. dollars; expected to be 394.35 billion U.S. dollars by 2016 (66% growth). Such enlargement in market size can tell better about the importance of cement. The hypothesis testing causal research had used to establish cause-and-effect relationship between implementing Lean Six-Sigma Methodology and improve the performance of cement production process through case study, including data collection and analysis at ＂ABC Company＂. By using of (DMAIC) which is a Six-Sigma approach, it gives a specific sequence of steps that should followed to define, measure, analyze, improve and control the production process. The implementation of Lean Six-Sigma Methodology improved product quality and increased the production rate in ＂ABC Company＂. This experience can expanded in other cement industry sites.
