Dr. Bruce E. Winston currently serves as a professor, teaching in the Ph.D. in Organizational Leadership and Doctor of Strategic Leadership programs at Regent University. His paper "The Four Cs of Christian Leadership" creates a beautifully biblical framework for leadership development.
The full paper is available here and is highly recommended reading. But to whet your appetite and send you back for more, here is a section from the conclusion of the paper:
"An organization’s leadership development program may be informed by this paper in that developing leaders should first be filtered/selected by their sense of calling and calling, followed then by education and training to increase their competence. Then developing leaders can receive counseling and education to increase their confidence and finally, developing leaders can be coached, measured, critiqued and developed in character traits."
