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).
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

not much specific to real time aspect, By
This review is from: Real-Time Agility: The Harmony/ESW Method for Real-Time and Embedded Systems Development (Paperback)
The book's title plays up the real time nature of the coding challenge. Yet a reading shows little that is specific to that aspect. Much of the book's advice could also pertain to more common, non-real time and non-embedded applications.For example, the book suggests frequent, incremental deliveries, including in a 'spiral' manner. This is not that different than other suggestions about agile approaches for a web site application. Amusingly perhaps, while the book talks much about agile, it says virtually nothing about Extreme Programming [XP] or its most 'extreme' aspect, pair programming. If you look up the index, those two entries are only mentioned once in the text, and then only as just those terms, without further elaboration. Whereas around 10 years ago, the term agile often was strongly coupled to XP and pair programming, if not outrightly conflated to those two. Yet possibly the experience of the intervening years has led the author to deprecate the... Read more

This review is from: Real-Time Agility: The Harmony/ESW Method for Real-Time and Embedded Systems Development (Paperback)
Bruce Powel Douglass's Real-Time Agility: The Harmony-ESW Method for Real-Time and Embedded Systems Development comes from a leading embedded-systems consult who covers model-driven development and agile methods, analyzing plans, requirements, and three levels of agile design processes. Examples pack a survey that can serve as a tutorial as well as a developer's reference guide.
