This Book is primarily focused on the educational needs of technical people such as engineers, technologists, scientists and technicians. Young engineers often find themselves in control of people and resources soon after they start their careers. Some may find themselves in a supervisory, management or entrepreneurial role much sooner than they would have imagined. Most engineers cannot escape involvement in commercial or administrative dealings with customers, suppliers, contractors, accountants and managers. For these and many other reasons, some engineering programmes include modules on communication, administration, engineering economics, supervision and management.
