When you prepare for the unknown you do two things in combination; you clean up the mess and you build pure and simple, open structures that give the right level of flexibility. This will never happen by accident. You will need an architecture tailored for this purpose.
If you are just aiming for goals and strategies with your architecture, you will slow down the change process. If you do not want to slow down the change process, you must in addition also prepare for the unknown.
Are you an architect? If you are – what is your goal? All architects, whether they design buildings, cities, landscape, or enterprises, must work towards a goal.
