Hansson advised that developers be open to changes in requirements. "What I realize is most developers really treat requirements as stone tablets," with commandments to follow, even developers using more flexible agile programming methodologies, he said. "There's not been a whole lot of talk in my mind about maybe you shouldn't accept these stone tablets."

To express his view that programs do not always need the most elaborate solution, Hansson compared the situation to different varieties a chocolate. Someone might do just fine with a piece of Twix chocolate even if the requirements called for fine Belgian chocolate. "Just giving them a Twix every now and then is going to be so much faster and cheaper," he said.
