For many years, those in the operations management community have debated the boundaries between manufacturing and service, recognising that the distinctions between them are becoming increasingly blurred. In business, this blurring is becoming more pronounced, especially with the emergence of new forms of contracting, often enabled by developments in information technology. Here we can see trends to offer a complete product and a one-off service (as in design and build in construction), and the trend to design/develop/make and operate a product, facility or service through-life (as in 'power by the hour' contracts in aerospace). In each of the papers in this e-book the challenges inherent in operationalising the product-service construct are explored, and strategies for enacting the approach are identified or constructed.
