For one bridge there should not be more than 4 participants in one team.

Material:
? 2-4 large buckets of Lego building bricks (2 for each team)
? Two tables that can be placed in a way that there is up to 150 cm
distance between them (the width of the river)
Schedule:
? 30 minutes for planning and prototyping (prototyping)
? 5 minutes for the final build from scratch (construction)
? 20 minutes for summary and discussion

Variant V1: Changing Requirements (ideal for software engineering and project
advancers and experts). Split the prototyping phase in two 15-minute parts:
? 15 minutes: Start with a 50 cm river to let the team come up with the
the wrong design.
? After 15 minutes introduce the new requirement of 150 cm
Variant V2: Team Competition - Set up two teams in the same room (ideal for
managers, in particular global software engineering project managers). Let the two
teams start and end at the same time (Of course, you need more lego material for
this variant!)
Assign bonus – points:
? 60 pieces = 100 Points when the bridge lasts one minute
? 1 point more per piece that was not needed of 60 peaces
(53 peaces needed ? 7 points, 66 peaces ? - 6 points)
? 1 point for each peace the bridge could hold during the stress test
