I have been reading a book called:
‘Plundering the public sector – How New Labour are letting consultants run off with 70 billion of our money’ by David Criag and Richard Brooks which I find very worth reading especially for me details of the expensive failures of various government IT projects and how the same mistakes were made again and again. But the book also goes much further than just mistakes made to detail how Consultants often act against the interest of government departments they give advice to; all backed up with quotes from those involved and from wide range of reports and sources.

One could make a good set of check lists for those in organisation that are undergoing process/organisation and information system changes, from examples featured in this book.
