The company I work for is very team-centric... every project has a formal team. Everyone on the team seems to be judged by the team's results and not as much if at all on individual contribution to the team, which is often hidden from more senior
We have teams for planning and teams for projects and teams for special projects and teams for weekly/monthly/quarterly activities of all kinds. Teams, teams TEAMS!
In my opinion, the main problem is that because team results are more analyzed than individual contributions, some individuals contribute much less than others. Get enough of these folks on any one team and it can be a nightmare for the one or two people who are left to produce the actual results.
That's a long explanation for needing some ideas for motivating these teams. Some teams are led by me and others I'm just a participant in. Anything you've experienced that works to any degree would be much appreciated. Thanks in advance!
