What a futurist does depends on the futurist. Futures thinking comes in many flavours depending on the type of work done, methods used, industry and functional focus.
The one thing that brings great futurists together is that they systematically, methodically and also creatively seek to understand the future and then make a difference to their context of focus.
Depending on the context and the problem setting this understanding then leads to more hands-on work relevant to that context.
The context could be in design, product, strategy, vision, research and many other areas of human effort to turn good understanding to decisions right now.
Without foresight you are left behind and eventually no longer have a purpose nor a seat at the table. It is a fact and now so obviously displayed in the world of business that it beggars belief why every business does not have a futurist working with them.
See you in the future.
