On-shelf availability
Measure how often products are on the shelf when customers look, and the sales lost.
Operations & supply chainRetail & ecommerce
How it's worked out
- OSA = available checks ÷ checks
- Checks spread across the day and week
NoteMany out-of-stocks are “phantom”: stock in the back room or system. Check replenishment from store to shelf.
