Example use cases
Seasonal sell-through acceleration check
“I've got 8 weeks of sales data for my product — each week shows units sold and how many days were in that observation window. Can you run an ordered trend analysis on the unit sales velocity to see if the sell-through rate is speeding up heading into the holiday season?”
New product launch velocity monitoring
“We launched a new SKU 10 periods ago and I want to know if unit sales velocity is trending up or down. Here are 10 rows of sold units and observed days — please do an ordered trend analysis so I can decide whether to increase our reorder.”
Comparing velocity across store formats
“I have 5 observation periods from a pilot retail program, each with total units sold and days of observation. Run an ordered trend analysis on the sales velocity so I can report to my team whether the rate of sales is improving or declining.”
