In social networking applications it's pretty obvious that the profile page tells others who a user are, and what her views are. That's how Facebook originally started its service: a users wall. When it was changed to a common flow there where protests (as always when there is a change).
But what about your work? At the corporate intranet there is usually a space where users can present themselves, store their files and keep track of tasks. In Microsoft Office 365 this is devided between OneDrive for Business and Delve. But the question is why it exist? Is there a need for a profile page (app) at work? Or is it there just because companies want a more "social networking" environment? Is it driven by user needs or company goals?
