Book excerpt: Models that explain what happened, that predict what will happen and that reveal how to get results are described in The Management Models Pocketbook - a practical resource for trainers, coaches and facilitators, and a ready-reference for managers. The range of models described, 10 in total, includes John Adair's action centred leadership model, Bruce Tuckman's team development and behaviour model, Eric Berne's parent-adult-child theory of transactional analysis and John Boyd's OODA decision-making model. There are models too covering delegation, motivation and communications. For each model described, author Mike Clayton outlines the problem that the model addresses, explains how it works (first an overview followed by a more detailed explanation) and uses examples to demonstrate how it works in practice. A diagrammatic view of each model and references to related models add to the practical approach. According to the 5-star review on Amazon: 'This is a brilliant book. The author has clearly and simply explained the models and how they apply to everyday business. A must for every training professional.'
