It was always the plan to bring things together, but just like the structure, it needed to be separate for a while for good reasons. We couldn't pick at store level the full Supercenter for a while. It's a lot harder to receive an e-commerce order and pick a toy at Christmas on time than it is to pick the strawberries every day, because you know where they are.

As it relates to brick-and-mortar, we've seen it all and done it all. We operate around the world in different formats, different brands. We've got large stores, small stores, all these different formats. So we know that space pretty well, but the e-commerce business was different.

There are all these things that add up into this business that's Walmart that keeps it really interesting. At the root of it all, though, it's a people business and it's a merchandising business. Today, it's increasingly a technology business. The supply chain is critical, of course, and real estate still plays a key role.

Always thinking about the customer value proposition is including price, assortment, experience, and trust, and all of those have been changed by technology and been changed by e-commerce, and so leading up to the moment when I took this role, there was an understanding that we needed to invest in e-commerce, grow e-commerce, but we didn't take it seriously enough.

The stores are an asset, and they have a great assortment in them and they're close to people. Being within 10 miles of 90% of America is a huge advantage, especially with fresh food at a good price. But we must also, if you think long-term and you think about what the company wants to accomplish, you must have a big and important first-party e-commerce business, and you must have a marketplace, and the things that go along with the marketplace.

By the time we got to 2020, we had leaders that had a stronger digital acumen, e-commerce set of capabilities and beliefs.
