Leadership, alongside material, technological and know-how resources, is the mix that generates growth and innovation. Of all of them, leadership is the critical one for building resilience against a growing number of disruptive factors. At the same time, leadership is rarely a single function, which creates a need for harmonisation and compatibility in how top management teams are built and how they operate. By understanding differences in personality, function, style and communication preference, and by pointing the team at something higher than its KPIs, management teams become genuinely symbiotic organisms.
