Developing a digital transformation strategy is one of the current priorities of organizations in the knowledge economy. Digital transformation consists of a restructuring of the business model and organizational processes aimed at delivering value and a better experience for customers, mediated by digital technologies. Digital transformation also involves changes in the behavior and mindset of stakeholders, such as leaders, team members, and even customers. Leaders need to be equipped with the competencies required by the Fourth Industrial Revolution (4IR) to drive a sustainable digital transformation movement. This work presents the Leadership 4.0 competencies involving and mobilizing Knowledge, Skills, and Attitudes and values, which can be used to identify leadership competencies gaps that limit digital transformation in the organizations.
