Need to know: most profitable products

What is the most profitable product and how much revenue did it generate in the last financial year?
Why you need to know
It is incredibly important for HR to know and understand the company's most profitable product(s), as you will need to be mindful of any impact that suggestions you make will have on the product or the way in which it is managed or run. Knowing not only what the product is, but also how much revenue it generates will help you understand what relative importance you should place in terms of your strategies and suggestions on the team that are responsible for delivering it.
