Francisco Inchauste unpacks the difficult process of designing simple products in Simplicity Isn’t Simple. He explains that simplicity isn’t just something you start tacking on towards the end of a project:

It still amazes me how many people ask for simplicity but don’t realize this phase of the design has passed when they’ve already listed out what they want it to do, or in the case of a Website, tell you what needs to be on the homepage.

True simplicity starts at conception. It’s infused into the being of the creators, and by proxy, in the soul of every product they design.

He also outlines some practical strategies for creating simple products.
