Purpose -An industrialized building system (IBS) is regarded as an effective residential building system that provides several benefits, including high quality, low cost, short time, good flexibility, reduced waste, and strong environmental performance. This system is considered to be valuable in promoting sustainable practices in China, where plans for urbanization have been established. However, the adoption of IBS in China is extremely limited. Potential risks exist and affect the attitudes of practitioners toward the use of this system. The purpose of this paper is to prioritize and analyze these risks and to develop corresponding strategies for mitigating these risks in China. Design/methodology/approach -In total, 24 risks that inhibit the implementation of IBS in China are identified through literature review and examined through interviews for consistency. A questionnaire survey is conducted to quantify the significance of these risks. Cronbach's coefficient α is employed to measure the internal consistency among the risk factors. The survey results are further analyzed using three case studies. Findings -The top five risks identified are "poor cooperation between multi-interface," "inappropriate design codes and standards for industrialized buildings," "lack of management practices and experiences," "enormous difficulty in achieving return on high initial investment," and "lack of a quality monitoring mechanism for the production process." The findings emphasize the government's leading role in promoting the new building system in its introduction and enforcement of adequate policies and regulations. Practitioners are also instrumental in establishing proper understanding and knowledge of IBS and its application. Originality/value -This study bridges the knowledge gaps on risk identification for implementing IBS in China. The findings provide practitioners and decision makers with valuable references for adopting adequate risk management methods and policies to promote IBS in China.

The research instrument is a tool used to collect data or measure objects of a research variable. To obtain the correct data for the conclusion that is in accordance with the actual situation, then required a valid instrument and consistent and appropriate in providing data of research result. Instrument reliability tests to include test-retest, equivalent, and internal consistency. Internal consistency tests have several testing techniques depending on the type of instrument. Testing techniques included split half test, KR 20, KR 21, and Alfa Cronbach. The value of the validity and reliability of an instrument is influenced by the measured subject, the instrument user, and the instrument itself. Sehinggga, validity and reliability must always be tested before the instrument is used.

“…• Q-squared for the predictive validity of the survey from a nonparametric perspective; acceptable Q-squared values, and their R-square values, must be greater than 0. • Cronbach's alpha and compound reliability index for internal variability of the latent variables; internal validity can be estimated based on the variance or correlation index between the items of a latent variable [61], and acceptable values must be greater than 0.7. • Average variance extracted (AVE) for the convergent validity of the items in the latent variables; acceptable values must be greater than 0.5.…”

Featured Application: The findings in this research allow managers to know quantitatively the importance of preventive maintenance in an adequate performance of total productive maintenance and productivity benefits in a production system, allowing them pay attention on those activities that are more important.Abstract: The present research proposes a structural equation model to integrate four latent variables: managerial commitment, preventive maintenance, total productive maintenance, and productivity benefits. In addition, these variables are related through six research hypotheses that are validated using collected data from 368 surveys administered in the Mexican manufacturing industry. Consequently, the model is evaluated using partial least squares. The results show that managerial commitment is critical to achieve productivity benefits, while preventive maintenance is indispensable to total preventive maintenance. These results may encourage company managers to focus on managerial commitment and implement preventive maintenance programs to guarantee the success of total productive maintenance.
