A process improvement methodology for effective implementation of value stream mapping integrated with foreman delay survey

摘要

Construction wastes, whether product or process, have escalated drastically in Indian construction context and have unfortunately become inevitable. To overcome a lot of inefficiencies in the traditional system, lean concepts have been introduced. Lean construction method is considered as the fundamental principle in identifying and minimizing the various wastes involved in the construction, yet faces challenges in implementation. This study aims to assess the process improvement methodology developed for value stream mapping. The aim also extends to further determine its applicability and develop the utilization of VSM as a prominent lean tool in the Indian construction industry. In addition, foreman delay survey helped to broadly identify the hidden wastes in order to get better insights for this research. With the involvement of industry practitioners in our study, it proved in an increase of 25% in the productivity. The paper successfully managed to build a better workflow and information-flow reliability, which helped reduce non-value added time by a significant amount.
