Nijhuis, S., Vrijhoef, R., & Kessels, J.W.M. (2018). Tackling Project Management Competence Research. Project Management Journal. Vol. 49(3) 62–81.

The vast amount of previous research on project management competence does not provide a basis for educational needs.
Analyzing previous research poses two challenges: the lack of a uniform list of competences, necessitating a taxonomy, and the use
of importance as a criterion, favoring general important competences. Criticality is introduced as the competence a project
manager adds to the team. Validation research using criticality and the taxonomy among experienced Dutch project managers is
more comprehensive and provides a lesser focus on general important competences than previous research. Criticality focuses
more on the essence of the profession.
