Software architecture metrics are key to the maintainability and architectural quality of a software project and they can warn you about dangerous accumulations of architectural and technical debt early in the process. In this practical book, leading hands-on software architects share case studies to introduce metrics that every software architect should know.This isn't a book about theory. It's more about practice and implementation, about what has already been tried and worked. Detecting software architectural issues early is crucial for the success of your software: it helps mitigate the risk of poor performance and lowers the cost of repairing those issues. Written by practitioners for software architects and software developers eager to explore successful case studies, this guide will help you learn more about decision and measurement effectiveness.Through contributions from 10 prominent practitioners, this book shares key software architecture metrics to help you set the right KPIs and measure the results. You'll learn how to:Measure how well your software architecture is meeting your goalsChoose the right metrics to track (and skip the ones you don't need)Improve observability, testability, and deployabilityPrioritize software architecture projectsBuild insightful and relevant dashboards

Today's programmers don't develop software systems from scratch. Instead, they spend their time fixing, extending, modifying, and enhancing existing software. Legacy systems often turn into an unwieldy mess that becomes increasingly difficult to modify, and with architecture that continually accumulates technical debt.Carola Lilienthal has analyzed more than 300 software systems written in Java, C#, C++, PHP, ABAP, and TypeScript and, together with her teams, has successfully refactored them. This book condenses her experience with monolithic systems, architectural and design patterns, layered architectures, domain-driven design, and microservices.With more than 200 color images from real-world systems, good and sub-optimal sample solutions are presented in a comprehensible and thorough way, while recommendations and suggestions based on practical projects allow the reader to directly apply the author's knowledge to their daily work."Throughout the book, Dr. Lilienthal has provided sound advice on diagnosing, understanding, disentangling, and ultimately preventing the issues that make software systems brittle and subject to breakage. In addition to the technical examples that you'd expect in a book on software architecture, she takes the time to dive into the behavioral and human aspects that impact sustainability and, in my experience, are inextricably linked to the health of a codebase. She also expertly zooms out, exploring architecture concepts such as domains and layers, and then zooms in to the class level where your typical developer works day-to-day. This holistic approach is crucial for implementing long-lasting change."From the Foreword of Andrea GouletCEO, Corgibytes,Founder, Legacy Code Rocks

This open access book provides an overview of the dissertations of the five nominees for the Ernst Denert Award for Software Engineering in 2022. The prize, kindly sponsored by the Gerlind & Ernst Denert Stiftung, is awarded for excellent work within the discipline of Software Engineering, which includes methods, tools and procedures for better and efficient development of high quality software. An essential requirement for the nominated work is its applicability and usability in industrial practice.The book contains five papers that describe the works by Jannik Fischbach (Netlight Consulting GmbH and fortiss GmbH), who won the award, entitled Conditional Statements in Requirements Artifacts: Logical Interpretation, Use Cases for Automated Software Engineering, and Fine-Grained Extraction, Christian Kirchhof's (RWTH Aachen University) From Design to Reality: An Overview of the MontiThings Ecosystem for Model-Driven IoT Applications, Sven Peldszus's (Ruhr University Bochum) research about Security Compliance in Model-driven Development of Software Systems in Presence of Long-Term Evolution and Variants, Florian Rademacher's (RWTH Aachen University) work on Model-Driven Engineering of Microservice Architectures, and Alexander Trautsch's (University of Passau) Usefulness of Automatic Static Analysis Tools: Evidence from Four Case Studies.The chapters describe key findings of the respective works, show their relevance and applicability to practice and industrial software engineering projects, and provide additional information and findings that have only been discovered afterwards, e.g. when applying the results in industry. This way, the book is not only interesting to other researchers, but also to industrial software professionals who would like to learn about the application of state-of-the-art methods in their daily work.
