Managerial experience
The higher up you are in an organisation, the more important vision and creativity become, but you still must have the skills required to manage and lead well. Some young entrepreneurs start with the vision and creativity and then develop their management skills as they scale their companies; others start with management skills and develop their creative vision as they climb up the ladder. Just like great musicians, all great managers have both creativity and technical skills. And no manager at any level can expect to succeed without the skill set of an organisational engineer.
