Anne Koziolek
2012 2012 First IEEE International Workshop on the Twin Peaks of Requirements and Architecture (TwinPeaks)  
It helps requirements analysts and software architects to study the quality trade-offs of a software architecture, and use this information for requirements prioritization.  ...  Quality requirements are main drivers for architectural decisions of software systems.  ...  analysis (step 7) determines the objectives which are actually conflicting so that the DM need to make trade-off decisions.  ...

How the understanding of the effects of design decisions informs requirements engineering

Zoya Durdik, Anne Koziolek, Ralf H. Reussner
2013 2013 2nd International Workshop on the Twin Peaks of Requirements and Architecture (TwinPeaks)  
The contribution of this paper lies in the explicit discussion of the effects of design decisions on requirements engineering.  ...  We define two types of design decisions and discuss their effect on requirements, and in particular on elicitation and prioritisation.  ...  This can lead to the quantitative support of taking trade-off decisions (in particular, trade-off between costs and quality properties or of two antagonistic quality properties).  ...

Autonomous Operations for the Crew Exploration Vehicle — Trade Study Design Considerations

James M. Crawford
2005 AIP Conference Proceedings  
Getting these trade-offs wrong can lead to unnecessary growth in mission cost and risk, and unnecessary decreases in the time the crew has available for core exploration tasks.  ...  The decision of how to distribute control must be based on a complex trade-off between development and validation costs, operations costs, and reliability/risks.  ...  ACKNOWLEDGMENTS The current trade study described here, "Trade Study on Autonomous Operations for the Crew Exploration Vehicle", is supported by the NASA Human and Robotic Technology initiative as part  ...

Optimising multiple quality criteria of service-oriented software architectures

Anne Martens, Franz Brosch, Ralf Reussner
2009 Proceedings of the 1st international workshop on Quality of service-oriented software systems - QUASOSS '09  
However, various degrees of freedom in building a software architecture span a large, discontinuous design space.  ...  The found optimal architectural models can be used as an input for trade-off analyses and thus allow systematic engineering of high-quality software architectures.  ...  Tradeoff analysis Based on the results of our approach, software architects can make well-informed trade-off decisions based on the available possible candidates.  ...

Identifying "good" architectural design alternatives with multi-objective optimization strategies

Lars Grunske
2006 Proceeding of the 28th international conference on Software engineering - ICSE '06  
Architecture trade-off analysis methods are appropriate techniques to evaluate design decisions and design alternatives with respect to conflicting quality requirements.  ...  However, the identification of good design alternatives is a time consuming task, which is currently performed manually.  ...  However, since the search space of architecture decision problems are often overwhelming; the benefit of using evolutionary algorithms as an input for decision making of an architecture trade-off problem  ...

Software Architecture Design Reasoning: A Card Game to Help Novice Designers [chapter]

Courtney Schriek, Jan Martijn E. M. van der Werf, Antony Tang, Floris Bex
2016 Lecture Notes in Computer Science  
Software design is a complicated process, and novice designers have seldom been taught how to reason with a design. They use a naturalistic approach to work their way through software design.  ...  In order to impart the use of design techniques, a card game was developed to help design reasoning.  ...  analysis, risk analysis, trade-off analysis and assumption analysis.  ...
