ABSTRACT
Although technology is being gradually incorporated in construction processes, the industry is still driven largely by the human factor. All levels of the supply chain are peopledependent: designers, contractors, subcontractors, and suppliers all interact to take a construction project from the owner’s project requirements (OPR) to the finished product. Improving performance, therefore, secures the greatest return on investment by addressing the human element. Performance improvement initiatives in construction encompass a wide range of alternatives. These include total quality management, Kaizen, Six Sigma, ISO 9000, and more recently, lean construction.
