I am working on an inventory management software. At times, when users add a batch or products or transfer items around, they would have a confirmation page to confirm their action.
For example, I added 50 products, each in a list form stating the price and everything. I press next, and it gives me a summary of the number of products I added, the total cost and etc. But all these information can be seen from the previous page. Should there even be a confirmation page? Or should it just automatically add everything?
The confirmation page (for me) might be an overview of their actions. Maybe they intended for 50 products but they accidentally pressed 500 in the previous page. One of my developer argues that users can always check for confirmation before proceeding, making the confirmation page useless.
"Every page should provide some kind of value or else take it out". What kind of value does the confirmation page provide?
