One of the initial starting points was for the concept to be reusable, both in idea and actual construction. It was also important for it to have a bold design element, the diagonal cut, so that it remains immediately recognisable even if the material and colour changes.
Another aspect of the design was for it to make use of the skilled workers at Mitab for the construction. I believe that everyone involved in the project shared the opinion that for the design to be good it would need to be clever.
