As systems grow increasingly large, complex, and costly, software architecture becomes ever more crucial. Software Systems Architecture, 2/e, is the leading practitioner's guide to designing and implementing effective information system architectures. Authors Nick Rozanski and Eoin Woods have systematically updated their highly-praised first edition, while retaining the clarity, accessibility, objectivity, and practical focus that have made it indispensable to working architects. Rozanski and Woods focus on real-world issues, superbly blend business and technical concerns, and offer insights that are relevant in all environments, regardless of methodology. Their extensive updates to this edition include:

• A new System Context Viewpoint, added to the authors' well-received architectural metamodel
• Expanded discussions of using architectural principles to provide traceability and expose decision-making rationales
• A discussion of how agile development and architecture can work together
• Updated, expanded description of enterprise architecture
• Expanded discussion of relationships between requirements and architecture
• New "Questions for Discussion"
• Updated bibliography and reading lists
