How to count, examples, etc. For small company not more 10 people right now (designers, developers, managers).
They use the term KRA for key results areas. Here's one reference from them but you should also browse around their blog and podcasts. There is a bunch of good information there.
Chris Locurto also has a bunch to say regarding KRAs: http://chrislocurto.com/?s=KRA
Hope that helps.
