This work is part of a series of management-training texts allying student-centred learning to core business knowledge. Each text provides a complete resource for managers, trainers and students of business who are studying at NVQ levels 4 and 5. In each of the main functional areas of business the books take a highly-developed activity-based approach to learning and link key generic management skills to underpinning knowledge and concepts. Using a wide range of examples and cases, this book is designed to enable managers to develop, implement and evaluate a business policy which should help them to achieve their organization's goals. It should also allow both the student and the manager to understand the interaction of the external and internal business environment.
