In recent years organizations of all kinds have learned that project working, once considered significant only for engineering and construction companies, can help to ensure that the intended benefits of business change will be realized in full and on time. This development means that more people than ever before need to understand the basic process, language and purpose of project working. That awareness is important not only for those actually engaged in project work, in all sectors of industry and commerce, but also for senior managers, project sponsors and the other stakeholders. The fourth edition of Essentials of Project Management is the junior complement to Dennis Lock's comprehensive, successful and encyclopaedic textbook, Project Management (now in its Tenth Edition). Essentials provides a concise, straightforward account of the principles and techniques of project management, designed to meet the needs of the business manager or student. Using examples and illustrations, the author introduces the key project management procedures and explains clearly how and when to use them. The Essentials of Project Management remains the ideal first text for anyone new to project working or students studying project management as part of a wider business qualification or degree.
