The State of Agile Software in 2018 (martinfowler.com)
On the surface, the world of agile software development is bright, since it is now mainstream. But the reality is troubling, because much of what is done is faux-agile, disregarding agile's values and principles, writes programmer Martin Fowler. The three main challenges we should focus on are: fighting the Agile Industrial Complex and its habit of imposing process upon teams, raising the importance of technical excellence, and organizing our teams around products (rather than projects), he added. An anonymous reader shares his post: Now agile is everywhere, it's popular, but there's been an important shift. It was summed up quite nicely by a colleague of mine who said, "In the old days when we talked about doing agile, there was always this pushback right from the beginning from a client, and that would bring out some important conversations that we would have. Now, they say, 'Oh, yeah, we're doing agile already,' but you go in there and you suddenly find there's some very big differences to what we expect to be doing. As ThoughtWorks, we like to think we're very deeply steeped in agile notions, and yet we're going to a company that says, "Yeah, we're doing agile, it's no problem," and we find a very different world to what we expect.
Our challenge at the moment isn't making agile a thing that people want to do, it's dealing with what I call faux-agile: agile that's just the name, but none of the practices and values in place. Ron Jeffries often refers to it as "Dark Agile," or specifically "Dark Scrum." This is actually even worse than just pretending to do agile, it's actively using the name "agile" against the basic principles of what we were trying to do, when we talked about doing this kind of work in the late 90s and at Snowbird. So that's our current battle. It's not about getting agile respectable enough to have a crowd like this come to a conference like this, it's realizing that a lot of what people are doing and calling agile, just isn't. We have to recognize that and fight against it because some people have said, "Oh, we're going to 'post-agile,' we've got to come up with some new word," - but that doesn't help the fundamental problem. It's the values and principles that count and we have to address and keep pushing those forwards and we might as well use the same label, but we've got to let people know what it really stands for. -
Pragmatic Project Automation
twelve71 (Alan Francis) writes "Apologies in advance for overuse of the word 'pragmatic,' but Dave Thomas and Andy Hunt together form a company called The Pragmatic Programmers, and published a book I'm sure many of you have read, titled The Pragmatic Programmer: from Journeyman to Master. The Pragmatic Programmer (or 'PragProg' as it is usually referred to) is a wonderful grab bag of 'good old common sense,' but its main strength (covering a very broad range of subjects) means that the authors have left a few holes around some important details. To plug some of these holes, and provide a good grounding for those just starting out, they have recently published 'The Pragmatic Starter Kit' - a set of books covering in detail some of the basics mentioned in PragProg." Read on for Alan's review of the latest book in the kit. Pragmatic Project Automation author Mike Clark pages http://www.pragmaticprogrammer.com/bookshelf/index.html publisher Pragmatic Bookshelf rating 9 reviewer Alan Francis ISBN 0974514039 summary Learn to use common, freely available tools to automate build, test, and release procedures.The first 2 (or possibly 3) books are Pragmatic Version Control with CVS and Pragmatic Unit Testing (which is available in Java and .NET flavours).
Pragmatic Project Automation is the latest book in the series and, interestingly, this book wasn't actually written by either Dave Thomas or Andy Hunt, but by Mike Clark (contributor to the 'Bitter EJB' book, editor of the JUnit FAQ, and responsible for the JUnitPerf and JDepend tools). Mike does a great job of ensuring this book fits in with the overall style of the other books in the series.
Up front, in case you're a "cut to the chase kind of guy," this book (and the others in the series) are must-haves and as a consultant with ThoughtWorks I'll have a set ready to distribute whenever I start working with a new client team.
Content The book helps the reader build a Java project slowly over the chapters, starting with a manual build-and-deploy process and automating a new aspect of it, chapter by chapter, until by the end of the book the software compiles, archives, deploys and configures itself multiple times a day. In addition, the build tools notify you of success or failure in a variety of interesting ways including email, SMS messages and different colored lava lamps.The first chapter provides a good introduction to the different types of automation available to projects. It also introduces the acronym 'CRISP' to help the reader remember the desirable characteristics of an ideal build process: Complete, Repeatable, Informative, Scheduled and Portable.
Chapter 2 gets you Repeatable by using ANT to bring together all the various steps you currently perform on your project into a single, one-click build. Chapter 3 works to turn the one-click build into a no-click build using tools as simple as cron as well as more complicated tools like the ANT scheduling tool CruiseControl. By the end of these two chapters your software can be compiling and testing itself automatically each time changes are checked into the version control system. But this is only the beginning.
Chapters 4 and 5 address the "Complete" and "Portable" portions of the CRISP model discussing how to include packaging, release management and deployment into your scheduled build. The last chapter addresses "Informative." How to monitor the build for success or failure, how to notify members of the project team using email, SMS, RSS or even the red and green Lava Lamps I mentioned above.
Summary This book, and the others in the series, provide a much needed set of manuals for getting a good set of basic practices up and running at the start of a project. Unlike the Unit Testing book, there's not a lot of programming in this one, but it's a worthwhile read for any programmer, regardless of experience level.Many people are becoming interested in eXtreme Programming and Agile methods for software development. These books help to support some of the key ideas of those methods - extensive unit testing and continuous integration.
The main flaw in the book doesn't affect its usefulness, only its readability. Of all the files used in the sample project, the only one covered in any detail is the build file. The source and manifest files that we're writing the ANT file to build are never discussed or described - we are left to guess at what the sample project might contain (unless we download the code from the website). While this didn't change what I was learning (how to manipulate the project files with ANT), I like to understand all the details and this omission did occasionally leave me a little irritated.

Stop Breaking the Build
Cap'n Grumpy writes "You know the score - you've just finished some coding, do a final cvs update before commiting, and all of a sudden all hell breaks loose. Your code now refuses to compile, or xunit starts flashing up red - test failures! One of the other members of your team has checked in something which breaks the build, and they just went out for lunch ... Argh! Did you know there is a solution to this problem? It is a system which makes it impossible for people to check in code which does not compile or test successfully. It allows coders to review others coding efforts code before it goes into the baseline, rather than after. It organises your checkins into logical change sets. It enforces continuous integration. It is linux based, and GPL'd. It's called Aegis." -
