In this book, first published in 1971, the author develops and tests a productivity system based on Added Value as the measure of company income and output. The theory behind the system is that the behaviour of a company can best be explained in terms of its need to create an income. From this, it follows that its effectiveness depends on the efficiency with which it uses all the resources at its disposal to create this income. If it is accepted that the need is to create an income, then the efforts of the employees, the objectives of individuals, the pricing procedures, and the control systems must be co-ordinated to achieve this end. This title will be of interest to students of management, economics, and business studies.
