I just signed the Manifesto for Software Craftsmanship:
As aspiring Software Craftsmen we are raising the bar of professional software development by practicing it and helping others learn the craft. Through this work we have come to value:
Not only working software,
but also
well-crafted software
Not only responding to change,
but also
steadily adding value
Not only individuals and interactions,
but also
a community of professionals
Not only customer collaboration,
but also
productive partnerships
That is, in pursuit of the items on the left we have found the items on the right (indented) to be indispensable.
I think this is an important addition to the Manifesto for agile Software Development.
