Sure thing. Keep it lean. Use a single sheet for all parts and rations and then a second sheet for totals. For the colors, stick to three: red for “needs replacement”, yellow for “low stock”, green for “good”. Use conditional formatting so it auto‑shifts when you change a value. Put a drop‑down list (data validation) in the “Status” column so you’re not typing random words. Add a column with a simple formula like =IF(A2<=5,"Red","") so the color updates automatically. Use a checkbox for “Used” so you can tick it off and the row disappears from the active inventory. For quick totals, pull a pivot table onto the second sheet that counts how many items are in each status. That’s all you really need, no fancy stuff. If you want to keep it realistic, treat the sheet like a living log: update it as you go, don’t let it pile up.

Lock the cells with the formulas and set the sheet to “protected” so only you can edit them. For the Friday spike just count how many rows hit the right color and stick a note in the top row for the winner. Don’t make it a big deal—just a quick check and a coffee for the winner keeps everyone honest. That’s it.

Got it, lock it and keep the coffee moving. Deadlines are on track, and Friday’s win will keep the crew on edge. Good work.
