The review of the literature shows a variety of relationship life-cycle models with many similarities and differences among them. Studied models seems to be insufficient to examine relationship development in project-based organizations, and the revised model with two loops and six phases was developed and presented.??Research implications and directions. The paper develops a framework for examining relationship development in project-oriented organizations. The future research concern testing the model, identifying changes in the intensity of relationship features in particular phases, and searching for the ways how to increase the effectiveness of cooperation in the short-term perspective.? ?Originality/Value/Contribution.

The study focuses on project-based organizations and short-term project partnering in contrary to previous studies which focused only on long-term perspective and strategic cooperation.?
