Honestly, I've found just acknowledging the hard work and effort they've put in, while in an all team context, is more rewarding than a trinket. The best reward you can give is your respect and appreciation, especially if given publicly, signaling that you value that person. You'll be a stronger team if you can show true appreciation for one another. (PS: Take the team out for beer too, obviously :) )
Agreed. As a few individuals have really make some big impacts I have been sure to thank them personally for working hard and helping us hit our date. I intend to thank the team publicly as well once we are live but I guess I was looking if there would be something in addition to verbal praising that would be meaningful.
Sorry, by publicly I meant in front of the rest of the team, not like in a blog post (which could be nice as well). Really you want to make them feel like a highly valued member of the team.
