The algorithm behind the components is the same as the one the Facebook social network uses.What is different is that the entire network exists within a member company. Catching up with long-lost classmates, sharing videos of piano-playing cats and swapping memes with friends is not part of the Facebook At Work experience.One reported feature unique to Facebook At Work is the alleged potential to use artificial intelligence to determine employee sentiment. This would make it possible for Facebook @ Work to learn how employees feel about topics within a company and share that information with company officials.A New Monetization PlanWhile specifics on the subscription charge are not available, the rumor mill reports that companies (no size restriction) will be able to sign up next month and use the platform for several months for free.Afterward, companies that stay on board will be charged a set fee per month for each “seat.” Facebook hopes the new revenue stream will be more reliable than what comes in from advertising on the social platform.There Will Be PartnersTechCrunch reported that Facebook plans to launch integrations or partnerships with other SaaS tool providers such as Asana, a Web and mobile app designed to help enterprise teams track their work.Familiarity May Breed SuccessFacebook At Work’s strength may lie with its familiarity. Millions of people know how Facebook works and how to negotiate its various components.By using the same algorithm and similar tools, albeit with different names, Facebook could virtually eliminate a learning curve for the new platform.An October launch of Facebook At Work would dovetail with Microsoft Corp.’s (NASDAQ:MSFTC) closing down of Yammer, set for January 2017. Microsoft plans to integrate Office 365 Groups with its current Yammer network.Facebook, however, could see and seize the opportunity to use its familiar interface to syphon off former Yammerers to Facebook At Work.Security MattersThe use of a self-contained platform guarantees companies privacy and security, something social Facebook can’t promise or deliver.Features such as single sign-on (SSO) secure identity management and the fact only employees of the member company can see work posted on that company’s platform enhance the secure environment.Related: HOW MUCH TIME SHOULD I INVEST IN MY PORTFOLIO?Chances Facebook At Work Will WorkWhether Facebook At Work will take hold remains to be seen.
