A white paper can wear many hats, and address different types of audiences.
As a technical resource, it can share functionality of a piece of software. It can also deliver highly technical information to architects and developers in a deep meaningful way. Or it can inform B2B buyers about the features of a big-ticket piece of industrial equipment, running into the millions of dollars.
But whatever piece of high-tech equipment it discusses, a technical white paper shares features and links them to real business benefits. Benefits the reader will enjoy once he owns your product or service.
