ABSTRACT
The construction sector is an immensely important industrial sector in terms of
economic and social impact and also employment facilities. Nonetheless, much
research has pointed out a gap in terms of labor productivity, quality, performance and
responsiveness to customer needs when compared with other large industrial sectors;
sectors that have recently experienced huge gains and cost reductions via methods like
Lean Six Sigma.

This paper presents a case study research which aimed to identify the potential Lean
Six Sigma implementation level in construction companies and expected benefits from
its use. Interviews were conducted in three companies in order to find out their
readiness for a lean management innovation. One of the companies was selected for
further study due to the suitability of its organizational structure and innovative
strategy to lean six sigma principles; and their interest in this study. The results of the
case study are analyzed and recommendations are made in the light of Lean Six Sigma
facts and principles.
