whats your process? im at a 6am store too and at first we struggled with it but we got it down. we have troubles now, but flow has shrunk to less than 10 people and sadly our hours have dropped so they cant hire. this why we have issue with coming clean.
things we did though that made a difference.
-have 5-6 people on the line for a half hour then send them to the floor.
-the etl or team lead need to be at the line and the other pushing where the wave begins so people dont slack.
-reduce your pullers, we had 6 then were down to 3, BUT market pulls the pfresh batches, and the backroom opener helps out too.
-if the first step wont work, then have fewer in at 6, and more in at 6:30. the first team to come in gets the truck going, the second half comes in when boxes are on the floor and has no down time at the start.
-only priortize the areas that are on the perimeter of the store, and then do the middle last.
-finally, keep the wave together and dont spread out too thin! you might think by hitting more areas you are getting more done, but really sprinkling here or there doesnt wet the garden.
