Having worked at PwC I think their employee portal tool called coyo has several benefits beyond just creating an internal community within our firm - The best thing though was being able achieve some of what we've been trying with other providers via Coyos capabilities which includes 1) better file sharing 2).
faster response times 3.) more customizability 4.). I like how quick we can add new pages or sections via our dashboard as well has easy navigation throughout all of my content! There really isn't anything i dislike about coyo atm but maybe there should be more options added into their site so they are creating an extension/addon where other users could use them too? It would just make things easier instead only having 1 user base using everything which makes life hard when trying multiple people with different needs working through each section etc..
