Description and importance of Inverted Doughnut model by Charles Handy:
A representation of how individuals and organizations can better manage change and focus on innovation. Unlike a real doughnut with an open center and solid material around it, the “inverted doughnut” has material at the core and empty space surrounding. The core represents the essential requirements of the job or project, the tasks and responsibilities that must be performed. The space beyond the core is the foundation for career growth and a high performance organization. It highlights the opportunity for initiative and creativity, going beyond what must be done, adding unique value and overachieving.
