You are provided with the abstract of a scientific paper and the abstracts of the papers it references. Your task is to write a Related Work section for the main paper. This section should concisely summarize and integrate the key points from the cited abstracts, reflecting how they relate to the main paper's contributions and context. In your summary, use numerical citation markers like [1], [2], etc., to refer to the corresponding papers.

Main Abstract:
Economic models of quality assurance can be an important tool for decision-makers in software development projects. They enable to base quality assurance planning on economical factors of the product and the used defect-detection techniques. A variety of such models has been proposed but many are too abstract to be used in practice. Furthermore, even the more concrete models lack an integration with existing software development process models to increase their applicability. This paper describes an integration of a thorough stochastic model of the economics of analytical quality assurance with the systems development process model V-Modell XT. The integration is done in a modular way by providing a new process module - a concept directly available in the V-Modell XT for extension purposes - related to analytical quality assurance. In particular, we describe the work products, roles, and activities defined in our new process module and their effects on existing V-Modell XT elements.

[1]: This paper generalizes our previous work on optimal and adaptive testing to consider a more general scenario of software testing resource constraints. The assumption is that software testing must be stopped once the allowed testing resources are used up. The contributions of this paper are as follows. First, we show that software testing with fixed resource constraints can be handled in the framework of the controlled Markov chains (CMC) approach to software testing. Second, an algorithm is adopted to reduce the computational complexity of on-line decision making in optimal and adaptive testing. Finally, the simulation results presented in this paper further confirm the effectiveness of the idea of adaptive testing in particular, and that of software cybernetics (which explores the interplay between software and control) in general.
[1] propose a method of optimal and adaptive testing with cost constraints. They discuss that it is effective to adapt testing and to explore the interplay between software and control. However, their model does only consider testing and is not explicitly integrated in a complete process model.
