Description
Real-time and embedded systems face the same development challenges as traditional software: shrinking budgets and shorter timeframes. However, these systems can be even more difficult to successfully develop due to additional requirements for timeliness, safety, reliability, minimal resource use, and, in some cases, the need to support rigorous industry standards.
In Real-Time Agility, leading embedded-systems consultant Bruce Powel Douglass reveals how to leverage the best practices of agile development to address all these challenges. Bruce introduces the Harmony/ESW process: a proven, start-to-finish approach to software development that can reduce costs, save time, and eliminate potential defects.
Replete with examples, this book provides an ideal tutorial in agile methods for real-time and embedded-systems developers. It also serves as an invaluable "in the heat of battle" reference guide for developers working to advance projects, both large and small.
Coverage includes
How Model-Driven Development (MDD) and agile methods work synergistically
The Harmony/ESW process, including roles, workflows, tasks, and work products
Phases in the Harmony/ESW microcycle and their implementation
Initiating a real-time agile project, including the artifacts you may (or may not) need
Agile analysis, including the iteration plan, clarifying requirements, and validation
The three levels of agile design: architectural, mechanistic, and detailed
Continuous integration strategies and end-of-the-microcycle validation testing
How Harmony/ESW's agile process self-optimizes by identifying and managing issues related to schedule, architecture, risks, workflows, and the process itself

Reviews / Votes
"Regardless of your perceptions of Agile, this is a must read! Douglass's book is a powerful and practical guide to a well-defined process that will enable engineers to confidently navigate the complexity, risk, and variability of real-time and embedded systems-including CMMI compliance. From requirements specification to product delivery, whatever your modeling and development environment, this is the instruction manual."-Mark Scoville, software architect
"This book will provide you with the framework of agile development for real-time projects ranging from embedded systems to web-based, data collection applications. I wish I had this book three years ago when we began a real-time, embedded drilling control system project, but all my engineers will be getting copies now that it is available. And, for my academic colleagues, this is the perfect book for graduate seminars in applied software development techniques."
-Don Shafer, chief technology officer, Athens Group; adjunct professor, Cockrell School of Engineering, The University of Texas at Austin
"We have used Dr. Douglass's books on real-time (Doing Hard Time, Real-Time UML, and Real-Time Design Patterns) for years. His books are always informative, accessible, and entertaining. Real-Time Agility continues that tradition, and I can't wait to introduce it to my colleagues."
-Chris Talbott, principal software designer
"Until now, agile software development has been mostly applied within the IT domain. This book breaks new ground by showing how to successfully traverse the perceived chasm between agility and real-time development. Although embedded systems impose challenging constraints on development teams, you can always benefit from increasing your agility."
-Scott W. Ambler, chief methodologist/Agile, IBM Rational; author of Agile Modeling

Person
Bruce Powel Douglass is chief evangelist for IBM Rational, a leading producer of tools for real-time systems development. He contributed to the original specication of the Unified Modeling Language and is former co-chair of the Object Management Group's Real-Time Analysis and Design Working Group. He consults to many companies and organizations on building both small- and large-scale, real-time, safety-critical systems. He is the author of several books showing how to apply software development best practices in real-time and embedded systems development, including Doing Hard Time, Real-Time UML, Real-Time Design Patterns (all from Addison-Wesley) and Real-Time UML Workshop for Embedded Systems (Elsevier).
