Foundations of Software and System Performance Engineering

The absence of clearly written performance requirements is the cause of much confusion and bad software architectures. This book's coverage of performance requirements engineering and domain-specific performance metrics at every stage of the software process addresses the problem. Application of the principles in this book will considerably mitigate the risks that performance post to the success of a software system and lead to a better quality product with wider acceptance.

• Focuses on the #1 cause of software project failure or cancellation: poor performance
• Covers the entire software lifecycle: requirements formulation, architecture specification, design, and functional and performance testing
• Introduces best practices for writing performance requirements, and linking downstream decisions to them
• Reflects the author's unsurpassed experience as both a practitioner and researcher, in environments including Siemens, AT and T Labs, and Bell Laboratories
