Thank you both for your replies.
I have to admit that I hadn't read those CAPS from the UK CAA. From what I have read from the UK CAA in the past they usually give good direction so I went on to read. The first CAP has been obsoleted from their system, but I was lead to another document that I think is going to prove quite useful: http://www.caa.co.uk/docs/872/SMSGui...anisations.pdf
I totally agree with you Saint Jack, if the management doesn't go with this implementation is going to fail. It is the same as for the Quality System. But for those operators I have in mind I'm not worried.
I have seen a few sites that advertise SMS for sale, but I just can't see it work. Actually those who offer Operations Manuals or Maintenance Exposition are also selling something that will never work. Both manuals, particularly the CAME, have so many particular procedures it will never work to buy and use something of the shelf.
