During the last thirty years, a wide range of product companies throughout the Western economies have considered moving into or setting up service businesses. Some have rejected the idea after careful consideration, some have wandered into competitive services without any real idea of what is involved and others have deliberately executed a carefully considered strategic manoeuvre. Included in this debate are some of the most famous business names in the western world: Unisys, Ericsson, Michelin, Nokia and HP. For IBM it was Lou Gerstener’s “big bet”; at GE it was one of former CEO Jack Welch’s “four major strategies” and, at General Motors, the financial services arm was its most profitable business for many years.Yet very little has been published on this profound transition. As a result, myths and idiocies abound. Some routinely claim that the “evolution from products through services to solutions” is inevitable. Others think that manufacturing is being outsourced to China and India while American or European teenagers face a career in hamburger stalls. The truth is much more fascinating.To succeed in a service business, most functions of a product company need to change. Operations, management, recruitment, finance, sales, new product development and marketing must all be adjusted. So the move into service therefore involves huge risk caused by disruptive and radical change.What has pushed realistic business people in such widely different industrial sectors to take so large a risk? Does their experience contain lessons or warnings for others? Is the trend likely to continue and affect other parts of the world as their economies develop? Will India, China or other developing economies need to learn how to export service once their manufacturing industries mature?
