Get a few colleagues together, and discuss specifically what your workplace could be like in 2020. Make sure your thinking is really about that future year. What will be true? What do you hope is true about the workplace, the work, and who does it? Who will probably still be there? Will older and younger workers collaborate well? Will age matter? Try to actually describe that future year in some concrete ways to each other.
Finally, you can step back and look at what you came up with. And finally, ask each other what it means today (2011) and what actions you ought to consider. Green Consulting Group and Leading Futurists LLC are ready to help, of course, but you can start this thinking all by yourselves. Give it a try!
