Service Engineering: Entwicklung und Gestaltung innovativer Dienstleistungen
Die schnelle und effiziente Realisierung innovativer Dienstleistungen stellt zunehmend einen Erfolgsfaktor für die Wettbewerbsfähigkeit von Dienstleistungsunternehmen dar. Dienstleistungen werden in der Praxis jedoch oft "ad hoc", d. h. ohne systematische Vorgehensweise, entwickelt. Das Konzept des "Service Engineering" beschreibt Vorgehensweisen, Methoden und Werkzeugunterstützung für die systematische Planung, Entwicklung und Realisierung innovativer Dienstleistungen.

Additional characteristics of a good network design include obvious and beneficial capabilities: user friendly, use of “state of the practice” rather than “state of the art” technology, upgradeable, secure, predictable, robust, and reliable (Hancock, 1990, pp. 68-69). It should be noted that the above characteristics are not mutually exclusive. Moreover, it is very unlikely for a given network architecture to satisfy all of the above criteria at once and the relative importance of a criterion is a function of several contextual factors.
Table 3 presents a summary of the effectiveness of the four networks in terms of various network architecture dimensions. 7 Three of the four networks – UNCTAD GTPN, Alcatel Telemedicine, and Johns Hopkins global access system—are mainly based on the Internet. The most important component of growth on the Internet is the demand for greater speed in the communications lines that make up the endto-end Internet. Since the basic design of the Internet is remarkably scalable,8 these three networks are likely to perform well on the scalability dimension.
As discussed in the previous section, the first and second level smart cards allow secure ETO, confidentiality, payment information integrity, authentication, etc. The Johns Hopkins Global Access System has similarly taken sufficient measures to ensure the confidentiality of patient records by using the Lucent Managed Firewall. Quality of Services Quality of service provided by a network should be evaluated in terms of customer expectation and the quality of alternative services. Since the networks discussed in this chapter are mainly designed to reach the global poor (or disadvantaged enterprises) who were previously unconnected by any other networks, it is difficult to judge the quality expected by the customers.
