I just came back from Nohau's seminar about QA/QC, and it was a good experience. It's nice to attend a seminar, that's free and not just a presentation of software, but also tries to raise the general knowledge level of the audience. If you haven't introduced QA/QC measures in your organization, yet, you should seriously be considering doing that.
I noticed, that most speakers were asserting that good quality requires the use of agile software development techniques. It's nice to see the software development business maturing.
