dnnrly asks: "I work for a company that writes software for the pharmaceutical industry. We have to work in quite a tight regulatory environment because some of our code ends up in the process of drug testing. Seeing as the FDA are quite picky about making sure that there can be no errors in testing new drugs, our clients have strict rules that we must follow for coding. We have to review all of the code that is written, making sure that everything is traceable to a design specification. Where we use 3rd party software/code we have to make sure that it comes from an ISO9000 source. This is a bit of a problem when we would like to use open source stuff in our code. Projects like log4net and NUnit would be tremendously useful in our code but we're not allowed to use them because they don't tick the right boxes. Now, *I* know that these projects (and others) are incredibly stable just because of the volume of use that they have seen but that isn't enough for some people. How can we certify such software?"
