An exercise I do with my graduate students that you can try for your organization is to describe all of the various systems in which you exist. Their answers start with the classroom and move beyond to the higher education system, to legal, natural, family, or body systems, to global economic and financial systems — and they operate in all of them.
So does your organization. So, to get good at strategic thinking, you need to try to understand the way your world works and how that affects you. Because you can’t really know everything, you’ll have to take your best shot at gathering the right information and prioritizing the components of systems that are most likely to affect the way you work now and into the future.
It really does help though to be curious about just about everything.
While you might be an expert in interpreting the particular “business ecosystem’ in which you operate, how well do you understand what is happening culturally or politically that might also influence your future?
Read a lot. Explore new things. Talk to people outside your organization and outside your discipline as well as the people who know your system the best.
