A product line for workflow management systems
This paper presents an ongoing research on the development of a component-based product line architecture for workflow management systems. The research includes a process to design the proposed product line, the population of the product with components, the product member production process, architecture evaluation mechanisms using architecture description languages and support tools, a variability management process and the development of case studies to evaluate each proposed technique

A component-based product line architecture for workflow management systems
This paper presents a component-based product line for workflow management systems. The process followed to design the product line was based on the Catalysis method. Extensions were made to represent variability across the process. The domain of workflow management systems has been shown to be appropriate to the application of the product line approach as there are a standard architecture and models established by a regulatory board, the Workflow Management Coalition. In addition, there is a demand for similar workflow management systems but with some different features. The product line architecture was evaluated with Rapide simulation tools. The evaluation was based on selected scenarios, thus, avoiding implementation issues. The strategy that has been used to populate the architecture and experiment with the product line is shown. In particular, the design of the workflow execution manager component is described

Software test automation : a design and tool selection approach for a heterogeneous environment
textThis report describes a design approach for implementing a software test automation solution that can accommodate existing test processes in an organization. The process of implementing a software test automation solution is a large undertaking and requires careful planning to avoid unsuccessful implementations. This report outlines a design that can integrate with existing business and development processes in an organization, and recommends automation and development frameworks for achieving the test automation goals.
Considerations for a heterogeneous test environment with varying types of supported operating systems, such as Windows and Linux, and multiple test execution environments, such as Java and .NET, have been made in this design and in the tool selections for the system implementation. The report also describes some of the challenges and caveats of automation in a heterogeneous environment along with recommended solutions to these challenges.Electrical and Computer Engineerin

Systematic evaluation of software product line architectures
The architecture of a software product line is one of its most important artifacts as it represents an abstraction of the products that can be generated. It is crucial to evaluate the quality attributes of a product line architecture in order to: increase the productivity of the product line process and the quality of the products; provide a means to understand the potential behavior of the products and, consequently, decrease their time to market; and, improve the handling of the product line variability. The evaluation of product line architecture can serve as a basis to analyze the managerial and economical values of a product line for software managers and architects. Most of the current research on the evaluation of product line architecture does not take into account metrics directly obtained from UML models and their variabilities; the metrics used instead are difficult to be applied in general and to be used for quantitative analysis. This paper presents a Systematic Evaluation Method for UML-based Software Product Line Architecture, the SystEM-PLA. SystEM-PLA differs from current research as it provides stakeholders with a means to: (i) estimate and analyze potential products; (ii) use predefined basic UML-based metrics to compose quality attribute metrics; (iii) perform feasibility and trade-off analysis of a product line architecture with respect to its quality attributes; and, (iv) make the evaluation of product line architecture more flexible. An example using the SEI’s Arcade Game Maker (AGM) product line is presented as a proof of concept, illustrating SystEM-PLA activities. Metrics for complexity and extensibility quality attributes are defined and used to
perform a trade-off analysis
PuLSE-I: Deriving instances from a product line infrastructure
Reusing assets during application engineering promises to improve the efficiency of systems development. However, in order to benefit from reusable assets, application engineering processes must incorporate when and how to use the reusable assets during single system development. However, when and how to use a reusable asset depends on what types of reusable assets have been created.Product line engineering approaches produce a reusable infrastructure for a set of products. In this paper, we present the application engineering process associated with the PuLSE product line software engineering method - PuLSE-I. PuLSE-I details how single systems can be built efficiently from the reusable product line infrastructure built during the other PuLSE activities
Creative products in international trade statistics
Changes in international statistics relating to the methods of classifying trade transactions in goods and services are analyzed in the further part of this paper. The author of the study makes also an attempt to evaluate if these changes are aimed at increasing the inclusion of embodied services and services delivered electronically into the value of international trade in services.Celem publikacji jest wykazanie, iż większość produktów wytwarzanych przez "przemysły kreatywne", to w rzeczywistości kreatywne usługi zawarte w towarach, a w międzynarodowej wymianie produktami kreatywnymi dominują produkty usługowe. W dalszej części publikacji analizie poddano zmiany w statystykach międzynarodowych, dotyczące sposobu klasyfikacji transakcji w handlu towarami i usługami. Autor publikacji podejmuje również próbę oceny tych zmian, pod kątem tego czy zmierzają one w kierunku zwiększenia stopnia włączenia usług zawartych w towarach oraz usług przesyłanych w formie sygnału elektronicznego do wartości międzynarodowego handlu usługami
