Successfully delivering Solutions via Patterns   In Patterns-Based Engineering, two leading experts bring together true best practices for developing and deploying successful software-intensive systems. Drawing on their extensive enterprise development experience, the authors clearly show how to deliver on the promise of a patterns-based approach—and consistently create higher-quality solutions faster, with fewer resources.   Lee Ackerman and Celso Gonzalez demonstrate how Patterns-Based Engineering (PBE) can help you systematically overcome common obstacles to success with patterns. By bringing discipline and clarity to patterns usage, their techniques enable you to replicate your success broadly and scale patterns to even the largest projects.   The authors introduce powerful ways to discover, design, create, package, and consume patterns based on your organization’s experience and best practices. They also present extensive coverage of the nontechnical aspects of making patterns work, including a full chapter of guidance on clearing up misconceptions that stand in your way. Coverage includes   Using patterns to optimize the entire development lifecycle, including design, coding, testing, and deployment Systematically managing the risks and economic returns associated with patterns Effectively implementing PBE roles, tasks, work products, and tools Integrating PBE with existing development processes, including eXtreme Programming, Scrum, and OpenUP Using Domain Specific Languages (DSLs) with patterns   Whether you’re an architect, designer, developer, analyst, project manager, or process engineer, Patterns-Based Engineering will help you to consistently derive greater business value and agility from patterns.
