You live in a volatile, uncertain, complex and ambiguous world.
Your customers’ needs and wants will continue to change and evolve.
So what can you do?

Business growth, a key process owned and led by the CEO or Managing Director; and cannot be delegated.
1. Leadership

Type of your leadership
Your team
Involving them in developing strategy as well as subsequent execution

You will have to aspire to transformational leadership. You used to simply tell people what to do and they would have got on with it (mostly, as they were generally self-motivated).
You might have either done all the processes in the business before being promoted or you have grown the business from its formation. However, often your team know more about a process than you do and so they have the answers (not you).
You need to work with the team for getting the best out of them.
