The study of service value networks adds a new dimension of investigation to industrial systems: human networks. Existing literature shows humans hyper-network to co-create value within and outside of the traditional structures of an organization or an extended enterprise – such as social networking for innovation and e-commerce for supply chain. S...

Service in knowledge-based economies represent a new mode of production: value co-creation between customers and providers. This mode inflates as the digital connections of persons, organizations, and resources reach every corner of the society. Hyper-networks result, representing the eco-system of the collection of such connections. The Internet i...
Article
Full-text available
The basic model argues that Digital Connections Scaling (DCS) of customers, providers and/or resources is a fundamental way to reduce service cycle time and transaction cost, and thereby to improve service quality and productivity. Digitisation makes entities connectable, and scaling decreases the marginal cost for the customer and the provider to...

Article
Full-text available
The problem of Database Query has always been considered from the user’s side. That is, the databases are always treated merely as the object of search, rather than being a subject or willing participants of an information exchange. This paradigm works when all participating databases belong to a single authority (such as a company) under which the...
