Inside Office 2016

Among the new additions in Office 2016 is one called Delve. "Delve will help individuals, teams and organisations to be more effective at work by understanding their reach and impact, time allocation and network," according to Kirk Koenigsbauer, corporate vice-president for Office. Microsoft claims Delve helps users discover the information that is likely to be most interesting. "You don't have to remember the title of a document or where it's stored. Delve shows you documents no matter where they're stored in OneDrive for Business or in Sites in Office 365," the company said.

People can also see colleagues' profiles, or edit their own. "Your profile is like an electronic business card you share inside your organisation," Microsoft explained.

One of the challenges for businsses is knowledge management - keeping track of who knows what. If it is widely adopted, Delve could offer a way for businesses to capture this knowledge.
