The ability it has helped me understand what my team is doing well as opposed having just been told by HR or management that we are great! It also gives you actionable recommendations so when I get back in touch they know exactly where i need help/where improvement needs happening.
Nothing specific but would like better reports coming out which helps us use our time wisely - reporting can be improved if there were some new features added such as graphs etc (which isn't too much work). Great tool overall once implemented correctly will provide good benefits both internally within your own organisation & externally towards customers who want insight about how things are going across various departments.
