Dear all,

These considerations might seem trivial or too evident to make them but I thought that they might clarify my opinion regarding periodical reviews.

While in Mumbai and hearing comments regarding the reviews, and in particular de discussion on periodical reviews and on demand reviews, I started thinking on the objectives of a review.  Why do we review?

A review of a structure, an organization or a process it’s not necessarily to change it.  A review allows you to verify that what you are reviewing is functioning as desired, fit for purpose, that you are obtaining the results as designed and if there is a way to improve it.  

Of course if you detect a problem, being that something is not working as it should or the results are not what was expected, then a review may be needed to detect the causes of the problem.

It is preferable to solve any problem that might arise before they happen, this is the reason why I think that the reviews should be, in general, periodical and not on demand.  An on demand review is required when a problem or an issue is detected, a periodical review may allow you to detect the problem or the issue before it happens and prevent it from happening.

Best regards,
