As the global population continues to grow, efficient construction methods without compromising project quality are needed. This study identified the critical success factors (CSFs) required for adoption of Industrialized Building System (IBS) in Malaysian construction industry (MCI). Preliminary factors influencing adoption of IBS from previous studies were contextually adjusted using pilot study. These factors were categorized into five areas: stakeholder understanding, resource availability, process management, issues and perceptions, and future needs. Questionnaires were then administered to 314 IBS players within MCI followed by data analysis methods. Relative Importance Index (RII) ranked increasing skilled labor, introducing renovation capabilities, and removing negative social perception as the main CSFs for adoption of IBS in MCI. The results of this study will be a guide for construction stakeholders to improve efficiency in construction by introducing IBS in MCI.

随着全球人口的持续增长，需要在不影响项目质量的情况下采用高效的施工方法。这项研究确定了马来西亚建筑业 (MCI) 采用工业化建筑系统 (IBS) 所需的关键成功因素 (CSF)。先前研究中影响采用 IBS 的初步因素使用试点研究进行了上下文调整。这些因素分为五个方面：利益相关者的理解、资源可用性、流程管理、问题和看法以及未来需求。然后对 MCI 内的 314 名 IBS 参与者进行问卷调查，然后采用数据分析方法。相对重要性指数 (RII) 将增加熟练劳动力、引入改造能力和消除负面社会认知列为在 MCI 中采用 IBS 的主要 CSF。
