A recent discussion on the Extreme Programming Yahoo Group explored the apparent conflict between making software reusable and the XP practice of not writing code until it is needed. Ron Jeffries and others shared insights about the costs and benefits of code reuse, as well as how and when to do it in an agile environment.
Uncle Bob Martin recently wrote about his experience with apprentices and what he considers key to progressing from apprentice to journeyman. He describes two hypothetical apprentices: Sam, a developer who has apprenticed with the same master and had the same year fifteen years in a row. Jasmine has changed jobs (and therefore masters) a number of times - growing her skills along the way.
Jay Fields presents several concrete strategies to go from "I think pair programming is a good idea" to "our team is successfully practicing pair programming and loving it!" He covers everything from pairing stations (the physical layout of your office space), to coaching tips, to common mistakes that those new to pair programming make.
Recently InfoQ reported on Jim Shore's 'The Decline and Fall of Agile', which highlighted a trend for organizations to adopt "Agile" (in name) but fail to adopt what it means to be Agile (in practice). Community leaders such as Joshua Kerievsky, Martin Fowler, and Ron Jeffries have taken Shore's post a few steps further recently, posting their own thoughts on what's going on with this situation.
In this interview taken during Agile 2008, Alan Cooper, the father of Visual Basic and supporter of interaction design, talks about his contact with the Agile movement and the similarities discovered between Agile programmers and interaction designers.
Pair programming and code review are each practices that improve the quality of software, as well as promote knowledge sharing. When the agile vs. lean, XP vs. Scrum, and vi vs. Emacs debates get slow, developers have been known to debate the merits of pair programming vs. code review. Theodore Nguyen-Cao described code reviewers as chickens, and paired programmers as pigs.
In this presentation, Kent Beck, the father of eXtreme Programming, shows the synergies between business and Agile development. The reason Agile is becoming more popular every day is because it responds to the business needs as they evolve.
Developers commonly break user stories into tasks to facilitate distributing the implementation work across the team, and allow tracking of progress at a finer level of granularity. Unfortunately, a story can explode into a list of non-trivial tasks so large that the story is not deliverable by the end of the iteration. Ron Jeffries suggests: "Do stories as a unit, not broken into tasks."
Recently there has been an active discussion in the Scrum Development Yahoo Group about handling an "under-performing" team member. In the 130+ response thread, "Rotten apple in Scrum team", talk ranged from advice for the primary question, to talk of team morale and who manages it, to the classic debate of measuring individuals, to distinguishing whether a team is really a "team", and more.
In this article, Mark Levison addresses the difficulties encountered by developers willing to adopt TDD, the reasons why many start using TDD but give up after a short period of time, and what could be done to help developers make TDD a habit.
In this original presentation from the Communitech Agile Event, Jeff Patton, winner of the Agile Alliance’s 2007 Gordon Pask Award, explains why one needs to embrace uncertainty in order to succeed with his/her Agile project and how to avoid some of the common mistakes leading to project failure.
Corey Haines has embarked on a unique personal "Pair Programming Tour". Now three weeks into this innovative journey, Haines has posted video interviews revealing many of the unique insights he's gained about pairing, automated testing, and the evolution of a software craftsman while sharing the keyboard at the home-bases of Dave Chelimsky, Brian Marick, Uncle Bob Martin, and others.
In this presentation filmed during Agile 2008, Jeff Sutherland, co-creator of Scrum, and Guido Schoonheim, CTO of Xebia, present an actual case of reaching hyper-productivity with a large distributed team using XP and Scrum.
In this presentation filmed during Agile 2008, Mitch Lacey talks about a real life project that was on the verge of being successful, but was deemed as unsuccessful by the customer. Considering that "the true measure of project progress is working software", Mitch and his team delivered the software, but the client was not satisfied.
In “Just Ship Baby” Kent Beck, author of the JUnit Framework, reminds us that the point of all the Agile processes and practices is to produce shipping software. If they’re getting in the way of shipping software – then perhaps you need to break the rules.
