I approach the work like this and appreciate others who do, but it doesn't scale. It's engaging and fun and can produce more elegant, attentive, humanized work. But larger technology organizations (or organizations pursuing larger projects) need to draw on engineering and factory models to meet their software development needs the same way that IKEA and GM draw on them. Just like in software, there are still countless master woodworkers and master mechanics who bring beautiful attention to their craft, but there is also a scale where that approach is simply not suitable. The different scales coexist and even comingle, and they're all valid.
