I'll go back to my colleagues, and ask them to expand on this, because they are leading the effort.
We're talking about 500,000 orders per year, 460 million items. There is complexity in the amount of materiel we're talking about. There is complexity in the number of locations from which it is managed. There is complexity in ensuring we have one system, from ordering to delivery, and performance metrics rather than the multiplicity of systems we use now.
We have decided to understand the problem before we rush in, and try to fix it. There have been attempts in the past, and those attempts have only looked at one or two aspects of the complexity, the range and depth of the problem. If we're going to do this, we're going to do it right. We have committed to timelines, and firm milestones on when things are going to get done, and we're happy to report back on those.
Troy, would you like to add anything else?
