Perhaps you can think of building a product this way, but the vast majority of products are businesses and you certainly can't build a business this way.
My take on the iterative process of building a product business would be more like this:
Research → Ideas → Idea → Confirm → Design → Code → Launch → Customer → Customers → Support → Marketing → Customers → Tweak (Code?) → ReLaunch → Support → Marketing → Customers
