Recent attention has turned toward developing early-career project managers, though research in this area remains in its early stages. As a result, project-based organizations often lack evidence-based strategies for fostering essential skills in their junior project managers. This chapter explores the first phase of a study aimed at understanding how early-career project managers are supported in developing three critical work-readiness attributes: decision-making, critical thinking, and confidence. These skills, identified by the global Project Management Institute, are crucial for early-career project managers. The study conducts a systematic literature review of four major project management journals—Project Management Journal, the International Journal of Project Management, the International Journal of Managing Projects in Business, and Project Society—to examine current research on these attributes. While all three skills are acknowledged as important, few studies specifically address how they can be developed, particularly in early-career professionals. The study found that confidence can be enhanced through feedback and organizational support initiatives such as mentoring and training. Research on critical thinking was limited, though one study highlighted the potential benefits of Tai Chi-based communication exercises. Decision-making was the most prominent attribute, with strategies such as gamification, professional development programs, governance structures, and emotional intelligence training aiding its development.
