The last 3 days I had the pleasure of attending an Architecture Workshop hold by Stefan Toth (@st_toth). We were designing and building a Lego Mindstorm ball path in 3 iterations.
He challenged us with difficult requirements, time restrictions, risk based priorities and much more. The team had great fun and learned a lot about the daily architecture work on the way.
Thanks, Stefan!
P.S.
