Very Interesting,
Then why not adopt a system used in another southern hemisphere member country like for instance Australias CASA. It would be alot cheaper and easier to implement and I believe that you might find same "quality concepts" as possible in their operations ? Traceability, customer service, excellence, reliability, safety, etc. That you are looking to implement in South Africa.
But I guess you already know that don't you!!!!!!
Keep It Safe!!!!
