What would happen if unfair or inaccurate reviews were left? Since the transaction can’t be reversed a person could be subject to abuse and unfair reviews which would affect their image. How’d you stop something like this from happening?
Such problems can be handled with a proper incentive plan. If vendor and supplier both give their view on a scale of 1-5 and then reviewers give their feedback we can get an understanding of how the reviewers rate and use data to develop a quality score of reviewers. This is a very simplistic solution to a complex question, but I am quite sure Daniel and his team will be working something much more sophisticated.
