Perhaps Mr. Brouillard can complete my answer.
In my case, the first obstacle is culture.
It's that fear of change that I think we see. People like what they have and they prefer that we just continue to allow them to do that. I often speak in analogies. There's too much customization. Everybody gets a custom suit, rather than being willing to go in and buy one off the rack that mostly fits. They're attached to their custom suits. We have to break that culture down.
For us to work, we want to work at speed at scale. That requires standardization. That requires departments to let go a little bit. It also requires us to actually make it work. Our track record in the past hasn't been the best. We've had some significant challenges, but I think we've shown through the pandemic and others that by simplifying, by standardizing, we can move at speed at scale, and there are real benefits.
I do feel that we are breaking down the cultural resistance.
