Tracks credentials easily, great visual Org Chart, all information is housed in one system (recruiting, timesheets, paystubs, tracking FMLA, employee portal, benefits, credentials, position information).
We now use one system when we previously had 5. Employees can update their own information. Recruiting is tied to position control, which cuts out constant tracking and miscommunications about how many positions are open. Real-time. Workflows save us from a lot of "signatures" we had to get for everything.
