Designs suffer from
- Too many – often wrong – assumptions are made
- Quick – often uninformed – decisions made
- Trade-offs with the decisions often not understood
Challenging these should be part of the behaviour.
People need to appreciate that they are working in a shared environment.
They should not feel interrogated or confronted, it should be natural, and they should feel comfortable discussing these.
Make it part of every design discussions.
Make time for it.
Make it part of the culture.
