Description
A Comprehensive Process for Defining Software Architectures That Work
A good software architecture is the foundation of any successful software system. Effective architecting requires a clear understanding of organizational roles, artifacts, activities performed, and the optimal sequence for performing those activities.
With The Process of Software Architecting, Peter Eeles and Peter Cripps provide guidance on these challenges by covering all aspects of architecting a software system, introducing best-practice techniques that apply in every environment, whether based on Java EE, Microsoft .NET, or other technologies. Eeles and Cripps first illuminate concepts related to software architecture, including architecture documentation and reusable assets. Next, they present an accessible, task-focused guided tour through a typical project, focusing on the architect's role, with common issues illuminated and addressed throughout. Finally, they conclude with a set of best practices that can be applied to today's most complex systems.
You will come away from this book understanding
The role of the architect in a typical software development project
How to document a software architecture to satisfy the needs of different stakeholders
The applicability of reusable assets in the process of architecting
The role of the architect with respect to requirements definition
The derivation of an architecture based on a set of requirements
The relevance of architecting in creating complex systems
The Process of Software Architecting will be an indispensable resource for every working and aspiring software architect-and for every project manager and other software professional who needs to understand how architecture influences their work.

Reviews / Votes
"The role of software architect has really come into its own in the last few years and is now recognized as a key determinant of project success. However, even today there is little common understanding of how to do the job: analyze requirements, understand concerns, evaluate alternatives, and construct and document an architectural description that is fit for purpose. Eeles and Cripps have filled this gap in their useful and practical book. The material is clearly and simply laid out, and follows a logical progression from inception through delivery, with tasks and work products clearly explained and illustrated using a real-world case study. This is a vital handbook for everyone from brand new architects to seasoned professionals."-Nick Rozanski, coauthor of Software Systems Architecture
"If you need a thorough and authoritative reference for a complete software architecture process, then look no further. Peter Eeles and Peter Cripps have produced a definitive guide and reference to just such a process. Being precisely defined using a metamodel, illustrated with a realistic case study, and clearly related to key standards such as UML, RUP, and IEEE 1471, the process presented in this book provides a valuable guide for those developing software architectures for large projects. I have no doubt that it will become a valued reference for many software architects."
-Eoin Woods, coauthor of Software Systems Architecture
"Eeles and Cripps distill years of experience into a single guide that helps the reader understand not just what architects produce, but how they produce it. The Process of Software Architecting is a very practical guide filled with lessons learned and pitfalls to avoid. Practicing architects will want to refer to it as they hone their skills, and aspiring architects will gain key insights that otherwise could take painful years of experience to acquire."
-Bob Kitzberger, program director, Strategy, IBM Software Group
"For most of my career in this field, software architecture has had the feel of being a black art that only a select few gurus and wizards had a talent for. This book follows on from industry best practice and a wealth of author experience to bring solutions architecture into the realms of being a true engineering discipline. Now I have a real guide I can pass on to new practitioners, a guide that embodies what used to require years of trial and error."
-Colin Renouf, enterprise architect and technology author, vice chairman, WebSphere User Group, UK
