Amazon is dominant not just in the world of retailing, but in the world of product management.
Amazon has idiosyncratic ways of doing things, and one of the approaches that has the most enthusiastic adherents is the PR FAQ.
This is a real Amazon PR FAQ for "Prime Pantry" and it adheres to the Amazon required format.
Here are some unofficial descriptions of the PR FAQ format.
Write an "Amazon" PR FAQ for a new product. (You need not hew exactly to Amazon's rules -- see in particular the notes in Robert Munro's article about possible deviations.)
You may pick any product that does not yet exist in the form you envision. That is, this could be a new product you are working on, one that a friend you know is working on, or one that you have been thinking about.
If you really can't think of a new product, then write a PR FAQ for an EMBA program that is based on a global cohort. That is, the cohort of students in the program normally reside in many different countries (such that physical colocation every other weekend would be impossible, and with a benefit proposition that includes the global diversity of the cohort).
