Robotic Process Automation (RPA) is kind of a confusing term. It's not about physical robots--instead, it refers to software bots that streamline repetitive and tedious processes in the workplace. Something else to note: RPA is the fastest growing segment in enterprise software, according to Gartner. As a result, the mega tech operators are looking at the market. SAP, for example, has acquired Contextor to bolster its efforts.
