The integration of all involved disciplines across the entire engineering life cycle is considered as a key element for improvements but requires appropriate conceptual support. Mechatronic objects provide such an approach. A criteria catalog for an assessment-based qualitative evaluation of respective engineering artifacts was developed, which aims to support characterizing, comparing, and improving mechatronic objects. In addition, it allows identifying directions for engineering improvements. In order to align future research efforts with industry needs, we conducted a survey among practitioners and researchers on their estimations regarding the potential of the mechatronic object concept and the implementation of selected criteria. This paper provides the results and insights from this survey and suggests a roadmap in order to improve mechatronic engineering.

Prototyping aims at transferring the costs from the operation and maintenance phase to earlier phases and to reduce the total software costs over the entire software life cycle. Experience has shown that prototypes are indispensable vehicles for obtaining valuable information and feedback in early phases of software development. The usefulness of prototyping has already been demonstrated in the field of business applications, where mostly user interface prototypes have been developed to specify and validate system requirements. This paper focuses on distributed process control systems. Developing prototypes is not easy in this field due to the special properties of such systems, e.g., real-time capability, distributed entities, elegant exception handling and recovery strategies, easy integrati...

There are different approaches to software development processes—more traditional approaches following and extending the spiral model (e.g., the Rational Unified Process—RUP) and more agile approaches such as Scrum, that try to integrate ideas from extreme programming (XP) and extreme modeling. Regardless of the software development process, the application of contract and scenario techniques is possible in all major tasks involved with software development (analysis, design, implementation, and testing).

We define different views of the term “type” and relate the type concepts of typical programming languages (e.g., Java) to syntactic and existential abstract types; that is, to types that are defined by sets of function signatures. Typical object-oriented programming languages are less flexible, as subclasses must have identical method signatures, although this is not necessary from the point of view of subtyping (contravariant argument types and covariant result types would be possible). At the behavioral level, algebras and axioms are important. They allow us to specify and prove the behavior of a type. We contrast this approach with the assertion approach and show the differences between the two formalisms. We also show that the subtyping rules identified for syntactic subtype relationships are also valid in the semantic case, and we present and discuss the axiom-strengthening rules for subtypes in the context of assertions. Additionally, we present some concepts for formulating contracts that have not yet been discussed, as they are not part of typical contract languages, such as Design by Contract in Eiffel or OCL.

There are others who approach the domain more skeptical [2]. Clearly, there is a gap in terms of how Agile is perceived. This gap could be reduced, if proper measures would have been timely employed. Agile maturity assessment models have been helpful in providing means and guidance for reducing this gap. Yet, a detailed look into existing models, comparative studies and literature reviews in the domain suggests that the agile maturity assessment models themselves are far from being mature. Further, the gap between what the proposed models offer and what industry really needs is frequently discussed by those comparative studies. In this study, we reflect on the existing agile maturity assessment models, compare them against a comprehensive set of criteria derived from the literature and from our background in assessing the capabilities of software development organizations. We conclude that none of the analyzed agile maturity assessment models are sound enough to be used in a practical context. Nevertheless, some of the models have interesting elements that can be reused for the development of a new agile assessment model.

An operational quality model often contains a large number of quality aspects and measures; therefore methodological support as well as tool support is necessary to adapt such a quality model to project-specific needs. Based on a general quality adaption framework we have developed a method for tailoring quality models. This method is supported by an accompanying tool. The application of the method and the tool in more than 40 projects proved the practicability of the approach. Nevertheless additional methodological support for deriving quality aspects or quality requirements from (business) goals would be desirable.

However, process improvement methods themselves typically do not deal in detail with the provision of guidance for the derivation of business focused process improvements. Therefore, we provide a best practice-based approach for developing and evaluating systems engineering strategies, based on a conceptual framework for defining and representing such engineering strategies. The resulting engineering strategies are aligned with corporate strategies and business goals. Strategy objects as a core element of our approach can be associated with the process areas and processes of existing process improvement frameworks. The presented approach thus allows that any process improvement action can consequently be systematically aligned with the strategy objects of the developed systems engineering strategies and thus with the business and strategic goals of the enterprise.
