I have a google alert that tells me when people write about 360 degree feedback.  It throws up some really interesting articles from people I would never come into contact with otherwise.

Over the break, I read this post on "are you measuring the things that really matter".  Within it is a section on supervisors.  It is a great insight into how supervisors (team leaders in may organisations) are the key to an organisation improving.  I used to manage a call centre and this is a mantra in those organisations.

I really like Mel's focus in this article and he highlights how simply 360 degree appraisal can be used as a method of getting feedback from direct reports (supervisees in his terminology).
