The skill sets that make a person an effective leader have been studied for decades and the findings show us that the foundational skillsets (building blocks) remain unchanged. Leadership at its essence is about mobilizing people in an organization around common goals to achieve impact, at scale. Harvard Business Review wrote the Leadership Handbook guide which took into account interviews from successful leaders across industries and sought prevalent themes throughout several decades of their own internal research in which they revealed 6 foundational building blocks. These same foundational skillsets are mirrored in Wiley’s findings which included a review of contemporary research and thought leadership in this field plus internal data spanning 20 years.
