The architecture of Lego

Some years ago I was asked to explain the concept of a product line architecture for some students that had not heard of the concept before. They were not very familiar with terminology used in the field of software architecture either so I had to do it on a basic level.

I decided to use an example outside of the software domain, namely the Danish toy system of Lego, since everybody in Sweden played with Lego as a kid. I guess the example looses it's pedagogical value if the audience has not seen Lego.

I did some revere engineering to identify architectural strategies and quality attributes. Pictures in the presentation are stolen from unknown internet sites...
