This is an excellent practical guide. It combines a genuinely systemic understanding of the design process with clear, comprehensive and extremely well-organized advice on every aspect of design and implementation. There is a wealth checklists and tools, all carefully framed within explanation of the place of each in the whole. Each chapter ends with a self-check, a list of do's and dont's and a 'bare bones' summary.
The book is written primarily for HR practitioners but will be equally valuable for line managers and for consultants.
