On 23 February, I gave a presentation on Unified Service Theory and perspectives on services as part of a study circle on service systems. Unified Service Theory views services as a special kind of production process where the customer contributes with her resources. This approach contrasts to earlier attempts to distinguish service through special properties like intangibility and perishability. The seminar also discussed additional perspectives on services based on the idea that the notion of service is best explained by identifying and associating a number of related concepts, including service processes, service resources and service agreements.
