Six-Sigma Based Approach for Productivity Improvement in Construction Projects

In order to improve the productivity of construction projects and achieve reliable workflow, it is necessary to quantify the eventual goals for the target process assessment. This research explores the feasible solutions for the construction performance improvement by use of the six-sigma principle, which provides appropriate boundaries of controlling critical sources of the variability. Then, a case study is performed with an aid of a simulation tool toward the end of this paper.
