This study aims to investigate the challenges to the implementation of value stream mapping (VSM) to enhance sustainable construction practices and determines its underlying factorial structure.
This study used a quantitative research approach, using a questionnaire survey to gather data. The collected data was analysed using statistical methods, including mean item score, relative importance index (RII), Gini’s mean and exploratory factor analysis.
This study revealed that language barrier is the topmost ranked challenge to the implementation of VSM in achieving sustainable construction projects. However, resistant to change with an RII of 0.700, when compared with the geometric mean of 0.6966 calculated from the stationary analysis was identified as the most consistent challenge. The research also identified two clusters of challenges: implementation and integration challenges and capacity building and process management challenges.
The research was conducted in Nigeria, specifically in the Federal Capital Territory. Thus, the results may not reflect regional disparities in construction methodologies, obstacles and the implementation rates of VSM in other areas of the country.
The finding of this study underscores the importance of fostering a culture that values innovation and continuous improvement within the construction sector.
This study adopted a robust analytical technique by introducing stationary analysis through the use of Gini’s mean to determine the most consistent challenge of VSM. Furthermore, this research is pioneering as it constitutes the inaugural effort within the Nigerian construction sector to methodically tackle these challenges, providing novel perspectives on the obstacles hindering VSM implementation.
