I'm Jon Coppeard, and I'm a seinor software engineer at Symbian.
For me software craftmanship is about always trying to produce the best quality software you can, so regular automated testing is something that's really proved is value in projects I've worked on. This is something that I think becomes more important as the size and complexity of the systems that you work on increases.
I'm interested in learning about all aspects of the development process however. Agile methods seems to be getting a lot of attention recently, and I'm interested to find out what experiecnce people have had with this kind of approach.
