In this paper we present a national project located in the area of computer aided testing and certifying (CATC) of physical devices. The objective of this project is to develop an Information System that supports the various activities of different user groups in a German federal institute of weights and measures. We decided to use formal methods right from the beginning of the project. Our approach is based on the formal object oriented specification language TROLL. Starting point of the development is an abstract model of the organization which will serve later on as a formal basis for implementation. We present parts of this specification and its relations with the underlying formal semantics. The experiences we made so far are rather positive and we expect further effects in the future.

The focus of this paper is on the modeling of application and business process in Cooperative Information Systems. Such processes use several resources and services to achieve a common, global system goal. We integrate the proposed concepts into the framework of a formal object-oriented specification language (TROLL). The goals of our approach are to provide additional modeling support for business and application processes, to explain these processes in the underlying framework and to couple tightly the modeling of global processes and the modeling of structural aspects of the system.
