The paper builds on a larger research study looking at developing a best practice framework for PPPs. An approach that is widely discussed in PPP literature and helpful in determining factors that exerts the biggest influence on PPPs success is the idea of critical success factors (CSF).

The main goal of the research is to enhance understanding of which factors are perceived as critical to the success of PPPs by different stakeholders groups on different stages of project life cycle. To examine perception of CSF within different stakeholder groups for PPPs a questionnaire template was conducted.
