The CPGs winning in retail right now have stopped treating on-shelf availability as a scorecard metric and started using it as a commercial lever - and it all starts with three questions most teams never think to ask.
While most CPGs track on-shelf availability, few can explain how those measurements connect to the trade investments, promotional decisions, or pricing moves. That gap between tracking a metric and using it to make better commercial decisions is where a lot of value can get lost.
The CPGs winning in retail today have figured out something different. They're using OSA as a commercial intelligence tool. They're asking harder questions about what their product availability information actually means for decisions about where to invest, what to promote, how to price, and where they have real negotiating power.
We spoke with commercial leaders who have taken the first steps on this journey. They shared three questions they're asking themselves - the ones that separate companies using OSA strategically from those just reporting on it.
Red flag: You know your overall OSA is 90%, but you don't know whether you're consistently understocked on some items and overstocked on others.
The real cost: Over-availability and under-availability create very different business problems, but most aggregate metrics treat them as equivalent. Under-stocking loses you sales, damages retailer relationships, and trains shoppers to buy competitors. Over-stocking ties up working capital, creates markdown pressure, accelerates obsolescence in seasonal categories, and fragments your inventory across customer accounts where it's not needed.
A category manager we spoke with discovered this the hard way: "We had healthy average OSA numbers, but when we looked at bias, we realized we were consistently over-forecasting demand for a particular set of items in a key midwest region. We had excess inventory sitting across stores, slowly moving at markdown. We were chasing OSA improvement that could actually hurt margin. Once we proactively collaborated with the retailer to fix this, we could reduce safety stock and achieve the same product availability targets with less inventory investment."
This matters even more during promotional windows. You might plan for a significant demand lift during a promotion, but if your forecast bias is consistently high, you will over-produce. You're spending on trade spend to generate demand you can't actually sell. Conversely, if you're biased low, you will run out of stock during the promotion window - the worst time to have poor product availability, because you've paid for the visibility and lost the sale.
Red flag: You're tracking OSA at the category level, but promotional decisions, pricing moves, and inventory investments are made at a much granular level. The measurement and the decision don't match.
The real cost: OSA can look healthy while individual stores run out of stock or pile up excess inventory. You might show 92% product availability across a retailer overall, but your “A” items could be at 78% in key stores while your “B” items sit at 98%. One of the reasons for this is you're measuring at the wrong level to inform the decisions you're actually making.
The pressure to get this right is growing. Retailers increasingly expect CPG support tailored to store format and local demand. A 90% OSA across your entire retailer base tells you nothing about whether you can reliably serve a high-volume urban format versus a small rural location. Aggregate-level OSA measurement can't support store-specific commercial strategies.
Red flag: Supply chain and commercial operate with different priorities and visibility into OSA. They're not aligned on what matters most.
The real cost: When supply chain and commercial operate in siloes, they make decisions based on different information at different times. Commercial launches a promotion based on forecasted demand. Supply chain executes based on an outdated forecast. Shelves are empty during the promotional campaign - the worst time to have poor product availability. You've paid for the visibility and lost the sale. Excess inventory piles up afterwards. Both teams blame each other, but the real problem is they were never on the same page to begin with.
On-shelf availability only creates commercial value when it influences how you make key decisions.
If your measurement approach doesn't reflect how promotional plans are built, pricing is set, and retailer negotiations are conducted, improving OSA scores won't improve business outcomes. Here are three things to focus on:
1. Prioritize what matters. Focus OSA improvement efforts on items, accounts, and time periods where product availability would actually drive commercial outcomes.
2. Connect to business outcomes. Track whether OSA improvements translate to lower inventory, higher sales, better margin, or stronger retailer relationships.
3. Break down silos. Make OSA a shared language between supply chain and commercial.
When these three things come together - OSA becomes your competitive advantage.
