Yes I encountered the case and it never worked. It seems very difficult to me to reconciliate approaches (with deficiencies I agree) requesting a complete spec in the beginning, with approaches tending to solve the probleme when and if you encounter them.

I appreciate your input, however, my question addresses a specific situation that some of you may have encountered in practice... It is such practical experience I am interested in... Let me rephrase... I was not very clear/accurate in describing my query... Have you encountered a situation, in industrial practice, in which an organization developing software following an agile methodology has to comply with a safety standard which has specific requirements on the software development process? A typical example of such safety standard, with respect to its requirements on the sw-dev, would be IEC-61508 Part 3 or DO-178...

Definitions always differ among the users of terms. But if the Agile methods being considered do not start with a complete and thorough specification of all the system/software safety requirements before anything else, then the system resulting system/software design will almost surely be less safe than one that does. Whether it coincides with other standards (most of which are very deficient with respect to safety) is not really important, is it?

Do any of you have practical experience with reconciling established agile software development with software safety requirements (e.g. IEC-61508 or DO-178..) ?
