Developing Workforce Capability in the Context of HR Ecosystem Learning
Human Resource Management Journal, EarlyView.ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed
