One of them, I would say, is about the operationalization of the building versus the construction. How can we do that better? We had a model. When it was developed it was that we finish the building—the construction, the structure and so on—and then we integrate the technology and the testing. We accelerated that process toward the end of the project, when we started to do it in parallel to basically shorten the time to operationalize and make the building fully operational. I think it's a qualified success, but I think we have learned that, if we want to do that and do it in a more serial manner, the way that we do the project—we've discussed it often amongst ourselves—is by zone. We need a clean zone before we start doing the technology.
