Agree with Go2TL, set workload is a make or break process for Home. You'll always have something to set and you'll always need a plan. If you don't, you'll drown in transition freight, half your endcaps will be dead and the other half will be split between clearance bursting through the seams and ancient or redundant SPLs.
For maintaining ECs, walk every day and make note of which ones need attention. Have your team get comfortable with flexing into ECs or knowing when to set new ones early from the future SPLs workload.
Freight flow is also something you just need to expect to be flexible with. Expect to be bombarded with so much of one department once or twice a week that there's no way your DBOs or regular TMs can handle it alone. Kitchen is a bitch in this regard and they'll just decide to hit you with 3 boats of repacks and 120 cases because product hit discontinue at DC or you've got revisions coming up.
