To deal with this problem Gotterbarn has devised a 'software development impact statement." This forces developers to identify anyone who could possibly be affected by a technology change, and for all combinations of project sub-taskers and stakeholders to ask: 'Could this development cause harm to this group of people?'

Too often developers are 'solving their problem, not your problem," said Gotterbarn.

'You're professionals,' he told the audience. 'When designers say, 'Do it this way' and you don't think that way will work have the courage and professionalism to tell them you think they're wrong.'
