Public Private Partnership (PPP) mode is a strategic step to boost infrastructure development in an economy. However, the achievement of this strategy depends upon the stress of its Critical Success Factors (CSFs). This research investigates the CSFs for PPP infrastructure projects in India. Using Principal Component Analysis (PCA), the study finds the factors-lack of community participation, lack of political will and absence of good governance-that delay the projects and make them financially unviable. © 2017 Taylor & Francis Group, London.
