Brian DeShong has posted some of his "food for thought" on the development process that's behind the scenes of different PHP applications.

Lately I've been doing a lot of thinking on development processes and quality, specifically for large-scale, professional PHP-based projects. [...] Generally speaking, my perception is that software development shops that really care about and emphasize quality have processes that consist of things such as writing use cases, unit testing and continuous integration.

He knows how he feels about all of this, be he wants to hear back from the community. How far does quality assurance go in your group? What kind of time/funding does this involve? Leave him a comment and let him know...
