In chapter 1 of the book the author has discussed some principles of management. Many managers, particularly senior
executives, are certainly concerned with these areas exclusively. In chapters 2 to 5, he discusses topics from areas of management called functional areas, viz., marketing, financial, personnel and
materials. It is at the functional level that management expertise has to be married to technical expertise, and functional technical knowledge is as important as managerial skill. This book amply
proves that golden rule.
