The 2004 Indian Ocean Tsunami triggered sig-nificant destruction to housing and related infrastructures across various coastal districts of south India.Research shows that tsunami reconstruction projects in Kerala experienced different degrees of success and failure.On this background,this study explored factors that con-tributed to the successful implementation of tsunami housing projects in Kerala by (1) consolidating various critical success factors (CSFs) for post-disaster recon-struction (PDR) projects under "project management suc-cess traits" through content analysis of existing literature;(2) deriving a conceptual model that envisages project success in PDR contexts;and (3) assessing the impacts of those success traits on tsunami housing projects using confirmatory factor analysis.Necessary data were gathered through a survey of various stakeholders involved in tsu-nami reconstruction projects in Kerala using structured questionnaires.The research revealed that PDR project success is attributed to critical dimensions of project management such as institutional mechanisms,recon-struction strategies,project implementation,and stake-holder management.A conceptual model with the interplay of project success,success traits,as well as their CSFs identified the project management actions that must be monitored during reconstruction.Since the project man-agement approach is widely recognized for PDR projects,these success traits hold huge potential for effective orga-nization and management of housing reconstruction pro-jects.The study also helped to identify project management traits that need improvements for the successful imple-mentation of post-disaster housing projects in Kerala.Thus the research findings can serve as a foundational study for formulating project management strategies appropriate to PDR projects in Kerala.
