I know almost no one does this, but I find it so strange given what we know about domain knowledge that it wasn't the natural solution to teach a bunch of the catalog staff PHP and make them the foundation of the ecommerce staff. You had people in there with 3-30+ years experience of knowing the ins and outs of Sears logistics, the product lines, the sales techniques, and the brand. They couldn't learn how to work a Wordpress site? Make a theme? Is it really always faster to take web devs and teach the entire rest of the domain to them? I wonder what it would do to the inertia and political gamesmanship issues (not to mention retention!) if a company gained the reputation for continuously training employees and executives to keep up with the latest and greatest, that if you were innovative and took initiative you would be ahead of outside hires for new, desirable roles.
