Very true. But not just the Treasury. There is a notorious cadre at AbbeyWood who think System Integration is an unacceptable risk and have been known to demand cancellation if it is even mentioned in supporting papers. I know one guy who took over a project and promptly waived the contractual requirement to integrate complex systems, thinking this constituted risk mitigation. He still paid the contractor in full, who of course were delighted. (The subsequent Board of Inquiry wasn't told this). Those who think it unavoidable know not to mention the dreaded phrase.
