Implementing and Applying Six Sigma in Construction

Abstract

Although Six Sigma has been implemented in the manufacturing and other services industries, it is still a relatively new concept in the building industry. This paper described the Six Sigma concept as a quality initiative that may be applied in the building industry. The principles, methodology, and metrics of Six Sigma are first discussed. The implementation phases as well as the training programs required are explained. A case study of how Six Sigma was pioneered in an organization in the building industry is presented. The findings suggest that management initiative and support, relevant training, appropriate selection of pilot projects, and commitment by team members are crucial for the successful implementation of Six Sigma in the organization. The application of Six Sigma for improving the quality of internal finishes during construction is also explained. Improvement measures taken by a contractor helped to raise the sigma from 2.66σ to 3.95σ for quality of internal finishes.
