QUALITY ASSURANCE INVESTIGATORS: NRI wants to improve methods for quality assurance investigations. Our belief is that our methods work well in any context, but we would like to find-out more from investigators in the field. We will use the information to improve our existing methods, particularly 3CA and ECFA+, to create new methods, and to move towards software implementation of methods. If you are able to co-operate, please contact us by email or via our mailing list. Thanks!
