This is possibly the worst textbook ever published in the English language. Massively overlong, extraordinarily tedious, strewn with numerous spelling and proof-reading errors, endless duplication, reams and reams of text without any bullet-points, paragraphs or diagrams. It frequently just cuts and pastes secondary material in without providing any commentary or context so that the reader can understand the relevance of the material or why he or she should bother to read it. The author frequently name drops other writers, again without explaining who they are or why we should regard them as a competent authority. Most of the business examples in the text seem to have been provided by the Daily Mail.
I can't believe that the UK Institute of Internal Auditors would have this book as their standard textbook for the MIIA course. Students of Internal Auditing would be much better advised to use the Tolley Corporate Governance Handbook, or indeed almost any other book.
