Marketing for the Developing Company (RLE Marketing) [PDF ebook] 

This book takes the reader through the underlying theory of marketing and applies it to the developing business. Research and analysis, testing and product planning follow, and lead on to more practical advice on small company sales organisation and control, advertising and promotion. Many practical examples of industrial and consumer goods marketing are given, and technical ‘jargon’ has deliberately been avoided to ensure a straightforward presentation of marketing facts.
