new tech training

hi everyone, new rxom here. i recently hired a new tech and looking for some insight. what do you guys think the best way to train a tech is? have them learn outwindow first or fill station?

when i was trained, i learned to fill first and familiarize myself w ic+ by looking up patients to change mfg and pfl etc. but that was at a different volume store. my new store is tier 5. any advice would be appreciated
