So now that I've worked in both plano and price accuracy I can see how e2e, when fully functional and staffed appropriately, would be preferable to how it's done now.
And it all comes down to plano, at least from what I've experienced. When plano is behind it really messes with flow, who are getting items that should already be out so they start flexing because shelves are emptying due a new pog. Price change swings through that area and it's really hard to find stuff when it's flexed so that metric suffers. Zoning would be super helpful at this point but who am I kidding? If we were there all the time we'd be familiar with the area and could likely find those 1 item price changes among all the mess.
Anyway...
Now, plano finally gets to that area and it's full so it takes longer to set because there is so much to downstock to get started and by this point quite a bit to backstock, taking more time. And the cycle continues because once you're behind how do you catch up??
All that to say that if one team did all those processes (except flow, we need them!) for an area it would make a lot of sense, imho.
