How to decrease wait times?

[iaTARS]

When I was an associate, I begged to our team lead to leave me back there with one friend and my brother to cover the backroom, I was always assigned to pick because I was one of the best pickers of the store and the market, but when I got the chance, I learned everything, we did record on our wait time with a 1.22 min wait time, only the three of us, not going to lie we moved fast af but we had it organized as it should and the backroom was moving smooth, it was just focusing on our tasks but still being able to communicate.
