for Trustworthy Software

For many years I have studied the major approaches for achieving
quality. Not just software quality, but quality of building anything.
Something that I have often wished for is an approach that integrates
all of these great concepts in one place
- not necessarily a unified process, but at least a big toolkit. I
think I have seen my wish realized in this book.
The main premise of this book is that software development and
manufacturing actually have more in common than many people have
believed in the past, and that like manufacturing, the place to improve
software quality is
"as far upstream as possible." This book has a framework of tools,
techniques and methodologies for developing robust software that is
based on the work of the quality gurus and companies worldwide. The
authors call this blend, Design For Trustworthy Systems (DFTS).
The book is divided into five sections:
Section 1 is a great background discussion that compares and contrasts
the most popular life cycle methodologies. This section has a good
discussion of software metrics and how to measure and compute the
financial impact of software quality.
Section 2 presents the tools and techniques for trustworthy software
and is the heart of the book. Interested in orthogonal arrays and
Taguchi methods? You’ll find an entire chapter on the topic.
Section 3 shows how to apply the tools and techniques early in the
Section 4 discusses how to implement these approaches in your
Section 5 has six major case studies of organizations that have
successfully implemented these techniques.
If you are looking for a book to dig deeper on software quality - more
than just testing
- this is a great book for that purpose. Each chapter has exercises,
review questions, discussion questions and projects.
Although this book has many great techniques and approaches for
developing and delivering trustworthy software, the authors make clear
that it takes more than just good approaches to deliver quality
software. They address why software quality is still lacking, even
though we have a great deal of knowledge and experience of what it
takes to achieve quality.
To quote from the book, "A breakthrough
quality never happens by itself. Neither is it the result of
incremental learning from your past experiences alone or because
everyone works harder and faster...It is invariably the result of
fundamental and irreversible changes directed by the CEO and the top
management team. These changes are planned and transformative as
opposed to haphazard and incremental. At the end of all the talk, it is
all about leadership."
I highly recommend this book to software quality leaders and
practitioners who want to go deeper in their understanding of what it
takes to build and deliver trustworthy software, and how to transfer
those practices to their organization to gain competitive advantage by
serving their customers better.
