Determine who your user is

The first and biggest question you need to ask, before designing a product that can be used by everyone is 'whom are you building for?'

When building their AstroBot Amazon made a list of potential user groups: software developers, business analysts, data scientists, designers, researchers, marketers. The product team reached out to potential users in those roles and spoke with them about their pain points and needs. 

On the basis of those conversations, the company determined that software developers were most likely to use the product.
