Thank you for your question.
It's a very interesting question, in my opinion. I believe that in the past, we were focusing solely on scheduling cost risks. Everything was about “give me the perfect plan, contain the costs”. We weren't behaving in an agile way, and we weren't focusing on the outcome risks.
Through the pandemic, we still managed cost, but we were far more aggressive on schedule. We didn't wait for the perfect schedule. We focused on the cost of not doing something, and that forced us to accelerate. I will be very candid. The early days were bumpy. They were messy. They were not perfect, but twice a week, we would literally sit down on the network and say, “What did we do on Sunday night? How did it work? Let's make changes on Wednesday.” We iterated quickly to fix our mistakes, to make things better faster. If we can continue to behave that way, I think we will be able to keep up this pace.
