Having ownership of the design encourages a more 'can do' attitude when tackling problems or mistakes that are discovered. Rather than blaming the design/build team for a problem, an operator with a stake in the design and construction of the project is more likely to look for solutions:
"You don't just say, 'Oh, I wish I had an electric socket there'. You say, 'Oh, I should have put a socket there - can I still do that, and what will it take to make the change?' … It's the difference between renting and buying. If you rent a place, you can either put up with not having a socket where you want it, or you have to approach the landlord, and the whole process might take a very long time, and you still might not get what you want. But if you own a place, then it's up to you, and if you decide you can afford to pay a bit more to get an extra socket just where you want it, then you can do that."
