Implementing Six-Sigma in an Organisation-Strategy

Hi all

I am a Snr Statistician for a phar. company and am interested in a strategy for implementing 6-sigma throughout the organisation.

Firstly i need to get a good grip.understanding of 6-sigma and am thinking of becoming accrediated as a Black Belt.

Does anyone have a plan-of-attack (i.e., strategy) of implementating  6-sigma in an organisation.

Is there a general recommended framework?

Comments/suggestions are most welcome.

Kind regards
