It is almost impossible to convince Camp One that its own intuitive thinking is problematic (at least, that is our experience). Suggestions that the customer's needs should be better understood, or that estimates should be created and risks assessed before commitments are made, are seen as luxurious or theoretical approaches. Camp One is sure that "This is the way we must work," and perceives that Camp Two has an easy life in an easy industry.
Camp One does change when it sinks under the weight of over-commitment and there are no longer any alternatives other than to plan and make sound commitments that customers can trust. Another situation that appears to cause the tide to change is the introduction of a new senior manager that insists on raising the bar someone typically from Camp Two.
