Abstract: "Functionally is a measure of how well a system does the work it was intended to do, but functionality is not all that matters in software development. Properties like interoperability, modifiability, and portability also matter as much as functionality does. These properties are determined primarily by the software structure -- or the software architecture. While many structures can satisfy functionality, few can satisfy the required functionally [sic] and the quality attribute properties needed in a system. Achieving quality attributes in a predicable [sic] way can only be accomplished by deliberately selecting the appropriate structures early in the development process. This is a radical departure from high speed, lightweight programming methodologies (e.g. XP) that focuses on functionality and prescribes writing software until a product emerges -- architectures also emerge in this paradigm. Emergent architectural structures may or may not meet the expectations of the broader stakeholders. Other methods espouse high ceremony processes and heavy emphasis on document production. The Architecture Centric Development Method (ACDM) can be differentiated from these extremes in that ACDM places the software architecture at the center of a development effort rather than software processes. Like architectures in the building and construction industries, ACDM prescribes using the architecture design to drive not only the technical aspects of the project, but also the programmatic issues of a development effort as well. ACDM weaves together product, technology, process, and people into a cohesive lightweight, scaleable development method."

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.

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.

Modern-day projects require software and systems engineers to work together in realizing architectures of large and complex software-intensive systems. To date, the two have used their own tools and methods to deal with similar issues when it comes to the requirements, design, testing, maintenance, and evolution of these architectures. Software and Systems Architecture in Action explores practices that can be helpful in the development of architectures of large-scale systems in which software is a major component. Examining the synergies that exist between the disciplines of software and systems engineering, it presents concepts, techniques, and methods for creating and documenting architectures. The book describes an approach to architecture design that is driven from systemic quality attributes determined from both the business and technical goals of the system, rather than just its functional requirements. This architecture-centric design approach utilizes analytically derived patterns and tactics for quality attributes that inform the architect’s design choices and help shape the architecture of a given system. The book includes coverage of techniques used to assess the impact of architecture-centric design on the structural complexity of a system. After reading the book, you will understand how to create architectures of systems and assess their ability to meet the business goals of your organization. Ideal for anyone involved with large and complex software-intensive systems, the book details powerful methods for engaging the software and systems engineers on your team. The book is also suitable for use in undergraduate and graduate-level courses on software and systems architecture as it exposes students to the concepts and techniques used to create and manage architectures of software-intensive systems.

Agile software development approaches have had significant impact on industrial software development practices. Today, agile software development has penetrated to most IT companies across the globe, with an intention to increase quality, productivity, and profitability. Comprehensive knowledge is needed to understand the architectural challenges involved in adopting and using agile approaches and industrial practices to deal with the development of large, architecturally challenging systems in an agile way. Agile Software Architecture focuses on gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox. Readers will learn how agile and architectural cultures can co-exist and support each other according to the context. Moreover, this book will also provide useful leads for future research in architecture and agile to bridge such gaps by developing appropriate approaches that incorporate architecturally sound practices in agile methods. - Presents a consolidated view of the state-of-art and state-of-practice as well as the newest research findings - Identifies gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox - Explains whether or not and how agile and architectural cultures can co-exist and support each other depending upon the context - Provides useful leads for future research in both architecture and agile to bridge such gaps by developing appropriate approaches, which incorporate architecturally sound practices in agile methods

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.
