Almost all doctors including clinicians need to have an idea about the principles of management. Most doctors have the responsibility for using of resources; leading teams or are involved in the supervision of colleagues. In addition most doctors work in managed systems. Doctors are both managers and are managed. Doctors use resources and play a role in setting priorities, developing policies and making other management decisions. In addition many doctors are working as mangers and executives themselves. Management is defined as getting things done well through and with people, creating an environment in which people can perform as individuals and yet co-operate towards achieving group goals, and removing obstacles to such performance. This book is about a useful set of principles for doctors who manage and non-mangers doctors also.
