The general approach in business to product development, product improvement, innovation and quality control is firstly to copy what works for other people.
It is only when you are:
(a) Already copying worlds best practice.
(b) Producing a world class internationally competitive product.
© Have run out of competitors processes to copy.
That you actually strike out into the unknown and through research and development come up with new and better ways of doing things.
Those observations explain why China and so called "Tiger Economies" can post 5+ percent GDP growth for decades….until the day they have exhausted ideas to copy and find themselves doing worlds best practice…then they have to chip away at the R & D coalface with the rest of us developed economies and be satisfied with 3.5% GDP growth if they are lucky.
The idea that CASA meets any of conditions (a), (b) or © is laughably ludicrous. We have **** people using and building **** processes based on **** ideas to produce **** regulations that have no possible basis in international norms that produce **** outcomes. To put that another way, we should be doing stuff exactly like no_one suggests!
I forget who said it: "The Galapagos islands of aviation regulation."
The obvious thing to do is to sit down with the NZ regulations and adopt them with as little change as is humanly possible. This is equivalent to the number one rule of software systems implementation ; "use an international standard package and change your systems to match the software, not the other way around".
