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.

Why’ Business ‘What’ Information Information systems Technology infrastructure ‘How’ ‘With what’ To answer the first question: IAF was originally designed to support the creation of architectures for Capgemini’s business. Capgemini’s business is all about business and technology transformation. So the topics we need to address are: 1. The structure of the business itself, otherwise we will not be able to understand which technology is needed to support or enable the business; 2. The way in which the business wants to process its information, as information processing is what the supporting technology does; 3.
This has been solved by the introduction of domains. A group of services is a component for which a solution as a whole exists, and that can function as a whole. In general each architecture will only contain one group for each required set of services. 11 Policy and Collaboration Contracts To create an architecture that works, there has to be a balance between supply and demand. In other words, the services have to be able to supply what the service consumers demand from them. An example will clarify the importance: If a pizza restaurant can bake 10 pizza’s a time, and it receives one customer that orders 8 pizzas, all is fine.
Actually this way of documentation can be used to describe functional and nonfunctional aspects of anything. The service describes what can be delivered (functional aspects) and how it should behave (non-functional aspects). The collaboration contract describes the way in which it is to be delivered in terms of the communication mechanism to be used and the syntax and semantics of how it can be requested. The communication mechanism effectively defines how fast, how secure, how often etc things can happen.
