can i ask what way you normally carry out your revalidation review for process and the frequency? Currently we do it every 3 years, it is a paper based excercise reviewing all finished product testing, stability results, change controls, complaints, deviations etc from the previous 3 years - basically a re-hash of the annual product reviews. Would be interested in other ways of looking at meeting this requirement to see if i can make this review more beneficial or at least a bit slicker - thanks
