Lean production is a well know managerial framework for optimization of organizational processes through waste elimination and cost reduction. Though many researchers pointed to the similarities between lean production and total quality management they do not usually proceed to conclusions about the possible impact of lean production practices on quality issues. The article undertakes the comparative theoretical analysis of lean production and TQM on two levels – on the level of general theoretical principles and on the level of the practical tools and techniques. The authors conclude that lean production practices not only can but should lead to the improvement of the quality of processes and products. The empirical analysis of the results of lean production improvement initiatives in 74 Russian companies leads to the same conclusion. The survey of the participants of lean production introduction projects in Russian companies shows that the number of the defects detected and corrected on the later stages of the value streams in these companies decreased. Hence, lean production can be considered as a set of tools not only for cost reduction but also for quality enhancement.
Rework remains a significant problem for construction projects. It is widely recognized that the cost of rework can have an adverse impact on project budgets and companies' performance. The issue of rework costs in construction projects can be addressed by the implementation of learning practices pertaining to quality management. However, the number of empirical studies that have sought to determine the impact of learning practices on reduction of amount of rework is limited. The research presented in this paper tries to analyze the correlation between the extent to which learning practices are implemented in companies and the impact on the rework costs reduction. Using a questionnaire survey, the data was obtained from 30 construction companies from Russia. The findings show the notable negative correlation between the extent of learning practices implementation and the changes in the costs of rework. The fuller the learning practices are implemented, the more the rework costs reduction occurs. At the same time, the extent to which the learning practices are used in Russian construction companies is from low to moderate. Therefore, the learning activities in the area of quality management should be fuller implemented in order to reduce the rework costs and ultimately improve projects and companies performance.
