Based on the viewpoint of project managers with regards to diversity, this paper used a phenomenographic method. Fifteen project managers were interviewed. The latter focused primarily on the variety of techniques, rather than on varieties of any other kind. This view of diversity extends beyond those angles generally taken in the literature on the theme which in most instances refer to diversity as based on gender, race and disadvantaged ethnic and minority groups. Additionally, the study brings to light the fact that diversities of knowledge and behavior are as beneficial for the development of projects. Furthermore, communication and the role of the project manager were raised as mitigating factors when it came to diversity. And, lastly, the conclusion arrived at was that project managers have similar discourses which correspond to the recommendation of the main project management manuals. These discourses and forms of expression are in most cases ready-made.
