Hospice,

Do you actually trust all the manuals around ?

Most of them are'nt worth the paper they are printed on.

LOL!

Prabhakar,

The Thing is Technology here has come a long-long way since those days when Planes crashed in the Real World(during Demonstrations).

However,that does'nt mean that Problems still don't happen-For instance in the case of Aircraft(remember all the problems that the 787 faced last year)??

It also does'nt account for Purposeful errors/cost-cutting which impacts on product performance(just like GM has recently faced).

Nimantha,

Now however,Thanks to Static Analysis Tools(from Coverity for instance) we are able to catch a signficant degree of Bugs in the Development Phase itself.

That's the Good thing.Sure there will always be some which escape onto the Deployment Phase-But then that's unavoidable currently.

You won't get 100% success with any Tool out there.

@Hospice: Yes certain bugs you cannot catch during the development stage. Most of the bugs will get caught once its being deployed and being in –use

"So the alternative is to put the product on the road and monitor its performance continously in real life situations and keep fixing the bugs."


Even tough it is impossible to catch all the bugs during the development phase, product safely laws recommend manufacturers to provide safety information - including studies or tests - that indicate whether a product meets the requirements defined in the consumer product safety act..

The problem with the Testing is that, whatever testing you do in the lab, it never really tests the real life situations to the fullest.

So the alternative is to put the product on the road and monitor its performance continously in real life situations and keep fixing the bugs.

Any kind of qualification tests to get safety certification may not bring out all the bugs that could be potentially hazardous in the real life situation.

 So like in Drug qualification tests , we need some gunea pigs who will be the first users of a newly devloped technology. 

 

Remember those airplane crashes at the beginning of the airline industry - without them we would not have come so far!
