At a time of unprecedented workplace flux, leader roles are constantly being redefined, requiring more finely attuned leader mindsets, frames for leadership, and skillsets for moving the dial on individual and organizational sense-making for cultural and institutional excellence. Based on five mindsets – Inquiry Mindset, Humanizing Mindset, Systems Mindset, Entrepreneurial Mindset, and Equity Mindset – the Flux 5 framework teaches leaders to drive adaptive change as a tool of professional and organizational development. Using embedded leader learning activations and organizational practices, the book guides leaders to develop each mindset as they read. The book encourages leaders (and their organizations in diffusion effect) to cultivate a visionary and resonant leadership approach at the intersection of crisis leadership, professional and human development, systems thinking, entrepreneurial leadership, and organizational equity frameworks. Succinct, accessible, pragmatic, and inspiring, this useful guide will grab the interest of leaders, teams, and organizations across sectors, organizational types, and business contexts, and engage professors, students, and practitioners of leadership, management, organizational psychology, and organizational development.
