Evaluating the performance (timing behavior, throughput, and resource utilization) of a software system becomes more and more challenging as today's enterprise applications are built on a large basis of existing software (e.g. middleware, legacy applications, and third party services). As the performance of a system is affected by multiple factors on each layer of the system, performance analysts...
Current service platforms, e.g. Cloud solutions, do not adequately address the requirements exposed from certain kind of services like real-time services. Infrastructure as a Service Platform (IaaS) supporting these service requirements, such as quality of service of the resources provided, heavily depend on measurements in order to be able to verify that the quality of service as contracted in a...
Service Based Applications (SBA) running in distributed and heterogeneous environments are subject to varying constraints that can lead to fluctuations in the quality of the application. We propose a solution in the form of a distributed framework for adaptation to improve in a autonomous way the quality delivered by those applications and to maintain it above a minimum level. This framework, named...
In this paper, we offer an approach for performing an organization-wide earned value analysis by taking advantage of the hierarchical structure of the GQM+Strategies grid. The merger enables us to create an integrated hierarchy of business goals, value goals, and strategies for achieving those goals and to monitor and evaluate those goals at all levels. It provides a means to expand the definition...
For monitoring, controlling, and improving software development projects, project and quality managers need tool support to analyze engineering processes within development environments. Unfortunately, technical and semantic gaps between the engineering tools and related data models make it hard to observe and analyze the implemented tool-based engineering processes. In this paper we build on a service-oriented...
Software cockpits (software project control centers) provide systematic support for monitoring and controlling the activities in a software development project. Important aspects are to track progress, to visualize team performance, and to provide feedback about the quality of delivered results. Therefore, software cockpits integrate and visualize data from various data sources such as project plans,...
