We use 15Five (employees spend 15mins/wk answering questions, managers spend 5mins reviewing). It's extremely valuable for measuring happiness and weekly goal attainment while soliciting ongoing feedback. What I like most is that it draws information out of those employees who prefer written over face-to-face interactions, and enables me to address 'concerns' before they become 'issues.'<p>15Five trial referral link: <a href="http://ssqt.co/tkdC" rel="nofollow">http://ssqt.co/tkdC</a><p>Edit: How does 15Five compare to Retroospect, now that I see someone from the team is on here?
