15-Minute Scoring
Win or Loss on Every Interval

FAQ
Common Questions
What is drive-thru speed of service (SOS)?
Speed of service is how fast your drive-thru serves each car, usually measured as average seconds per car or a win rate against a target time. It's one of the most important levers for throughput and sales in a QSR.
How does Zairo measure SOS?
Zairo scores every 15-minute interval as a win or loss against your SOS target, then breaks performance down by day part and identifies your weakest hour with a specific recommendation to fix it.
Can I see SOS by day part and hour?
Yes. Zairo reports SOS per 15-minute interval and rolls it up by day part (breakfast, lunch, afternoon, dinner, late), and it pinpoints the single weakest hour of the day.
Do I get alerted when SOS misses target?
Yes. Zairo fires a critical SMS alert the moment speed of service misses target by 10% or more, so a manager can react during the shift rather than reading about it the next day.
