The survey asked a lot of questions about which products we've purchased. And that didn't seem necessary.
Why? Because a large company (heck, even a medium sized one) in the 21st century should have ready access to detailed sales data.
The "drivers" and "key performance metrics" of their business...
They should know which products are selling well and which ones aren't. They should know volume and sales $$ data They should know the data by product, by region, by customer type/demographic, by store, or any other data point that's meaningful to them..
So, assuming the above, why would they need to ask customers this information in a survey?
It makes sense for them to ask us about Future purchase preferences, but not about past purchases.
