Agile! The Good, the Hype and the Ugly

A few years ago I became fascinated with agile methods: with the unique insights they include; with the obvious exaggerations and plainly wrong advice they also promote; and perhaps most of all with the constant intermingling of these two extremes.

I decided to play the game seriously: I read a good part of the agile literature, including all the important books; I sang the song, became a proud certified Scrum Master; I applied many agile techniques in my own work.

The book mentioned above is the result of that study and experience. It is both a tutorial and a critique.

The tutorial component was, I felt, badly needed. Most of the agile presentations I have seen are partisan texts, exhorting you to genuflect and adopt some agile method as the secret to a better life. Such preaching has a role but professionals know there is no magic in software development.  Agile! describes the key agile ideas objectively, concretely, and as clearly as I could present them. It does not introduce them in a vacuum, like the many agile books that pretend software engineering did not exist before (except for a repulsive idea, the dreaded “waterfall”). Instead, it relates them to many other concepts and results of software engineering, to which they bring their own additions and improvements.

Unfortunately, not all the additions are improvements. Up to now, the field has largely been left (with the exception of Boehm’s and Turner’s 2005 “Guide for the Perplexed“) to propaganda pieces and adoring endorsements. I felt that software developers would benefit more from a reasoned critical analysis. All the more so that agile methods are a remarkable mix of the best and the worst; the book carefully weeds out — in the terminology of the title — the ugly from the hype and the truly good.

Software developers and managers need to know about the “ugly”: awful agile advice that is guaranteed to harm your project. The “hype” covers ideas that have been widely advertised as shining agile contributions but have little relevance to the core goals of software development. The reason it was so critical to identify agile ideas belonging to these two categories is that they detract from the “good”, some of it remarkably good. I would not have devoted a good part of the last five years to studying agile methods if I did not feel they included major contributions to software engineering. I also found that some of these contributions do not get, in the agile literature itself, the explanations and exposure they deserve; I made sure they got their due in the book. An example is the “closed-window rule”, a simple but truly brilliant idea, of immediate benefit to any project.

Software methodology is a difficult topic, on which we still have a lot to learn. I expect some healthy discussions, but I hope readers will appreciate the opportunity to discuss agile ideas in depth for the greater benefit of quality software development.

I also made a point of writing a book that (unlike my last two) is short: 190 pages, including preface, index and everything else.

The table of contents follows; more details and sample chapters can be found on the book page listed above.
