  abstract     = {{The software specification acts as a bridge between customers, architects, software developers and testers. If information gets lost or distorted when building this bridge, the wrong system will be built or the system will not be built in time and budget–or both! Standards and recommendations give advice on how to structure specifications or check software-engineering artefacts with reviews or inspections. But these constructive and analytical approaches are not well integrated with each other. Moreover, they are often too generic to efficiently support the specification of particular system types. In this paper, we present the integrated “specification framework” of Capgemini sd&m. It consists of our specification method for business information systems (BIS) and its concerted analytical counterpart, the “specification quality gate”. Since this framework is tailored to the specification of large BIS, it allows a quick ramp-up phase for software engineering projects without the need for extensive tailoring or extension.}},

  abstract     = {{Visual Process Pattern (VPP) is a visual language to describe constraints on the behavior of UML Activities. They have been developed for the sake of formulating and verifying requirements on business process models (with Activities being one possible description language). In the VPP approach, a visual pattern is translated into an LTL formula, which can then be verified against a transition system describing the behavior of the Activity under consideration. In this paper, we aim at generalizing VPP. We show how to formulate patterns more generally, using either concrete or abstract syntax of the behavioral model under consideration. Additionally, we describe how these more general patterns can be verified against a model’s behavior.}},

  abstract     = {{Business-driven development favors the construction of process models at different abstraction levels and by different people. As a consequence, there is a demand for consolidating different versions of process models by detecting and resolving differences. Existing approaches rely on the existence of a change log which logs the changes when changing a process model. However, in several scenarios such a change log does not exist and differences must be identified by comparing process models before and after changes have been made. In this paper, we present our approach to detecting and resolving differences between process models, in the absence of a change log. It is based on computing differences and deriving change operations for resolving differences, thereby providing a foundation for variant and version management in these cases.}},

In a case study, the Use Case Point (UCP) method was applied to 15 commercial software development projects. The estimated efforts were compared with the incurred project efforts. We measured a standard deviation of 42 %. This is not acceptable for industrial usage. Therefore, we propose appropriate improvements of the Use Case Point method leading to significantly higher estimation accuracy with only 20 % standard deviation. The contribution of this paper is a detailed description of the improved Use Case Point method.}},
