As a TM of fulfillment (SFS, OPUs, and grocery), I have a few tips that help me be more efficient at picking and have a lower INF rate.
1. Use your tools. A.) In ePick: Picture, location, DPCI, text. B.) MyWork to see: Backroom location, additional sales floor locations, last delivery date, last sell date, and quantity. E.G., if you can't find it and it says there are 0 on the sales floor 0 in the backroom (48 on hand) and the delivery date is MORE RECENT than the last sales date, it's probably in the backroom lost on a uboat.
2. What to do when you can't find it and using your tools and eyeballs is failing you: ASK a TM in that area, check reshop, check general area for that type of product, check endcaps and sidecaps in the area in case other locations aren't listed, check near the cash registers (or know what products are pushed there), and check the clearance rack for missing softlines.
3. Talk to your TM and TL. When you finally find that one missing box of Cat and Jack masks in the back, TELL YOUR TMs and TL; they'll be looking for them, too.
4. Ask questions, play with MPM and MyWork.
5. As you walk from one location to another, LOOK AROUND to see what has changed in the store: new endcaps and sidecaps, misplaced or new products, etc.
6. As you approach the product's location, try to see it before you get there.
7. If the barcode can be scanned without touching the product, do that before or as you pick it up.
8. Place all products that need to be prepped on one side of the cart, if possible, to make it easier on preppers.
9. Talk to TMs in other departments and be appreciative of their work and help. A better relationship means they'll be more willing to help you when you need it. Offer to help them in return without being asked.
10. Care about other TMs and their stress.
11. Always be honest, but polite, especially when you fuck up.
