....management tools directly support high level executives in analyzing and changing the way an orgnaization achieves its goals. Obviously, this requires the representation of non functional goals as well as the representation of the ways how process alternatives contribute to these goals [CKM 91]. Such non functional requirements can emerge from informal or semi formal discussions [HJR90] or they can be axiomatically derived from economic theories, such as the theory of value added chains [PM85] The following figure, expanded from one shown in the chapter by John Mylopoulos (cf. also ....

....for the rest of the discussion we will speak of goal satisficing [42] 3 to suggest that generated software is expected to satisfy within acceptable limits, rather than absolutely, non functional requirements. 2 An earlier version of portions of this and the next section have appeared in [13]. 3 [42] actually uses the term to refer to decision methods that look for satisfactory solutions rather than optimal ones. The term is adopted here in a broadened sense since in the context of non functional requirements, even the notions of a solution or optimality of a solution may be ....

....be generated by the simple example we have been introducing piecemeal. In the bigger picture of information system development, a source object, say a component of a requirements specification, is mapped into one (or possibly several) target object(s) say components of a design specification [13]. The dependencies among these objects are shown through dependency links on the left and right hand sides of Figure 2.1. The use of the goal structure generated by the designer from non functional requirements, possibly with the help of methods, is intended to help her select among alternatives ....

In between, object management tasks such as version and configuration management are the domain of programming in the large [48] Here, we only sketch an in thesmall and an in the many model. In a Telos model used intensively throughout DAIDA [16] [33] programming in the small is understood as a set of interrelated design decisions which transform design objects into other design objects, supported by design tools. Design tools are modeled by the special kinds of design decisions they support. Design goals are a special kind of design ....

....are systematically integrated into the development. They are represented as potentially conflicting or synergistic goals. In one of the top goals of Figure 1, for instance, Security is the sort and Account is the parameter which typically represents information items such as attributes [8, 9]. Now the developer can decompose the goal either on its sort or on its parameter. 2 We used the Subsort method to decompose the goal into three other goals for accuracy (the faithful reflection of information) confidentiality (guarding against unauthorized disclosure) and availability ....

....in the requirements of efficiency (e.g. complexity theory, queuing theory) and reliability (e.g. fault tolerance, formal verification, recovery) has progressed quite far. Recently, some information system specific requirements such as data accuracy and security have also been investigated [Chung et al. 1991, Mylopoulos et al. 1992] A third approach is the half axiomatic, half empirical derivation of non functional requirements from processoriented theories of the firm, such as the theory of Critical Success Factors developed by Jack Rockart at MIT or the theory of value added chains introduced by ....

For a formal specification, we may start with this initial definition: accuracy as a requirement for an 4 This section is adapted from [Chung91a]. information system reflects the faithfulness of the information maintained by the system with respect to the application domain . Unfortunately, this definition is not quite formal: what do reflects and faithfulness mean, and what is information Below we clarify our definitions; in ....

....looks appealing to programmers. The system will be extended with a mapping tool. The aim of the mapping tool is to map the specification of his problem to an expression of the refinement meta language. A such tool will be interactive. Such mapping tools have been developed in other frameworks in [11], 91] for mapping requirements to designs. The system incrementally will increase its programming knowledge. Design decisions will be shifted from the programmer to the system. 7.4 Contributions This thesis presents a new schema based method of programming in logic which advances previous work ....
