Another article in ComputerWorld "IBM: Tapping Employee Brain Power" led to Tony Karrer's blog entry and Paul Coyne's comment.

From the ComputerWorld article "Armed with the freshly-minted corporate values, senior management charged business unit managers to find and close the gap between those values (three corporate values mentioned above this) and actual business practice. To help with that, IT rolled out in October 2004 a so-called jam - a worldwide brainstorming session that Truskowski describes as 'a blog on steriods'.".
...
"A top-rated idea from the 2004 jam was a program in which employees can anonymously rate their bosses."
...
"Another tool for harvesting ideas is the Technology Adoption Program, or TAP, an initiative aimed at the company's new goal of fostering innovation".
