Thank you for taking the time to write about how effective change occurs - and is also sustained. I remember a presentation I attended on this topic where they showed those silos as you mentioned. It was a relatively new concept at the time, but so important to our working together to stop being so territorial and come together with shared knowledge. Teams work so much better, gaps are closed, and goals can be accomplished when knowledge and processes are shared. I was born with the idea that if I learn something new I have to share it so others can learn it too.
