Even though there are many different definitions of competencies, the following two definitions are appropriate given the international nature of the projects analyzed in this paper. Competencies for project management can be defined as the knowledge, aptitudes, attitudes, and behaviors that are needed to carry out a piece of work that has a definite starting and end point (Boyatzis, 1982, 1996). Competency represents the ability to demonstrate appropriate behaviors in the application of relevant knowledge and skills in order to achieve effective performance in the context of a specific project (Hager & Gonczi, 1996).
