Weekly roundup: Agile Day insights

You always learn something new at conferences. The most valuable insight I got from the Italian Agile Day, held last friday in Genoa, was:

Building construction as a metaphor for software development is a frequent misunderstanding. In construction, you have an architect for the design phase and hundreds of workers for the actual construction. In software, the deliverable of the design phase is the source code, and the construction consists in an automated build. Therefore, you have no workers, and everyone is an architect. -- from the keynote of Paolo Perrotta
