To my knowledge, reviewing is not considered part of a job description. Reviewing generally falls into the category of "research" and is thus the responsibility of the individual customer. The value of good reviewing needs to be brought to the attention of all stakeholders involved. Some people think that reviewing is paid work. I also learned that some people think reviewing is not much work. However, depending on the kind of product, it can be a lot of work. I think the basic principle of having independent and objective reviewers is imperative to a honest review.
