Book Description
Software Engineering significantly matured in the last decades, but still many projects suffer from delays, exceed their budget, do not reach their quality goals, or even fail. We experienced that many industrial projects suffer from a misalignment of software architecture and software project plan. Other engineering disciplines like manufacturing put specific focus on aligning product design and production plan to prevent problems during production. In this thesis, we introduce the alignment of software architecture and software project plan as a new quality property of software called producibility and propose a method to analyze the producibility of a software product. The producibility analysis method semi-automatically detects critical architectural elements and project planning elements like work activities, iterations, or assigned resources that are supposed to cause delays or effort overhead during realization of a software product. In an industrial case study, we identified more than 90% of critical elements up-front. We determined based on estimates of the project team that we could have saved 29% of time in the first of two iterations.

Book Description
To fully leverage the value of software architecture in enterprise development projects, you need to expressly and consciously link architecture with project management. This book shows how, drawing on powerful lessons learned at Siemens, one of the world's leading software development organizations. The authors offer insight into project management for software architects, insight into software architecture for project managers, and above all, insight into integrating the two disciplines to maximize the effectiveness of both of them. Learn how to develop cost and schedule estimates for development projects, based on software architecture; how to clarify architecture so projects can be more effectively planned and managed; and then how to use architecture to organize, implement, and measure the project iteratively as work progresses.

Book Description
Architecture-centric development is a novel software paradigm that uses software architecture as a centerpiece to drive other development activities, such as program development and testing. Existing studies in this area are limited to the conceptual analysis of architecture-centric development. In this project, we propose to perform an empirical study based on an existing architecture mapping approach. To that end, we used a video game application as a case study. We recovered and developed an architectural model for this game application using the ArchStudio and xMapper software toolset. We made some modifications to the game using the architecture-centric approach. The result shows that architecture-centric development is applicable to the implementation of a real software system and can automatically maintain architecture-implementation conformance. The study allows us to further analyze architecture-centric development practically for other different applications. The architecture-based system that we developed can also facilitate the future research of software architecture.

Book Description
This cumulative habilitation thesis, proposes concepts for (i) modelling and analysing dependability based on architectural models of software-intensive systems early in development, (ii) decomposition and composition of modelling languages and analysis techniques to enable more flexibility in evolution, and (iii) bridging the divergent levels of abstraction between data of the operation phase, architectural models and source code of the development phase.

Book Description
This open access book presents the outcomes of the “Design for Future – Managed Software Evolution” priority program 1593, which was launched by the German Research Foundation (“Deutsche Forschungsgemeinschaft (DFG)”) to develop new approaches to software engineering with a specific focus on long-lived software systems. The different lifecycles of software and hardware platforms lead to interoperability problems in such systems. Instead of separating the development, adaptation and evolution of software and its platforms, as well as aspects like operation, monitoring and maintenance, they should all be integrated into one overarching process. Accordingly, the book is split into three major parts, the first of which includes an introduction to the nature of software evolution, followed by an overview of the specific challenges and a general introduction to the case studies used in the project. The second part of the book consists of the main chapters on knowledge carrying software, and cover tacit knowledge in software evolution, continuous design decision support, model-based round-trip engineering for software product lines, performance analysis strategies, maintaining security in software evolution, learning from evolution for evolution, and formal verification of evolutionary changes. In turn, the last part of the book presents key findings and spin-offs. The individual chapters there describe various case studies, along with their benefits, deliverables and the respective lessons learned. An overview of future research topics rounds out the coverage. The book was mainly written for scientific researchers and advanced professionals with an academic background. They will benefit from its comprehensive treatment of various topics related to problems that are now gaining in importance, given the higher costs for maintenance and evolution in comparison to the initial development, and the fact that today, most software is not developed from scratch, but as part of a continuum of former and future releases.

Book Description
Abstract: "The Rational Unified Process (RUP) is used broadly by software developers. This technical report fits the Carnegie Mellon[registered trademark] Software Engineering Institute's (SEI's) architecture-centric methods into the framework of the RUP. These methods include the Architecture Tradeoff Analysis Method[registered trademark], the SEI Quality Attribute Workshop, the SEI Attribute-Driven Design method, the SEI Cost Benefit Analysis Method, and SEI Active Reviews for Intermediate Design. Since the key process milestone of the Elaboration Phase of the RUP is a completed architecture, the architecture-centric methods appear early in the process during the first two phases (i.e., Inception and Elaboration). This report presents a summary of the RUP and then examines the potential uses of the SEI's architecture-centric methods."

Book Description
This is a practical guide for software developers, and different than other software architecture books. Here's why: It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face. It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties. It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts. It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail. It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.

Book Description
Verifying the security posture as a system evolves is indispensable for building deployable software systems. Traditional security testing lacks flexibility in (1) providing early feedback to the architect on the ability of the software to predict security threats so that changes are made before the system is built, (2) responding to changes in user and behavior requirements that could affect the security of software, and (3) offering real design fixes that do not merely hide the symptoms of the problem (i.e., patching). We motivate the need for an architecture-level testing for security grounded on incremental and continuous refinements to support agile principles. We use architecture as an artifact for initiating the testing process for security through subsequent and iterative refinements. We extend the use of implied scenario to reveal undesirable behavior caused by ambiguities in users’ requirements and we analyze detection their security implications. This approach demonstrates how architecture-centric evaluation and analysis can assist in securing systems developed using an agile development cycle. We apply this approach to a case study to evaluate the security of identity management architectures. We reflect on the effectiveness of this approach in detecting vulnerable behaviors and the cost-effectiveness of refining the architecture before vulnerabilities are built into the system.
