This assessment is built on two established followership frameworks:
Kelley, R. E. (1992). The power of followership: How to create leaders people want to follow, and followers who lead themselves. Doubleday.
Chaleff, I. (1995). The courageous follower: Standing up to and for our leaders. Berrett-Koehler.
Both frameworks are presented as taught in:
Northouse, P. G. (2025). Leadership: Theory and practice (10th ed.). Sage. (Chapter 13, "Followership")
