During our Agile Experience session with a client a couple of weeks ago, Chet and I were helping them with FitNesse for .NET. We thought it would be interesting to get FitNesse working with Ruby, so we've begun to work on that. Here, the results of that trial ...Now! With new explanations and graphics! See the end of the article.Lire l'article

On a few of the Agile lists, Paul Arrowood asked: "How does Agile address a conventional Risk Log? I wouldn't call these 'blocked items' (aka issues). But more or less the [Scrum Master's?] watch list for things that could go awry (content not fabricated, new/unfamiliar technology, geographically dispersed team, interdependence with another project, etc)." I wrote an answer, and liked it well enough to put it here.Lire l'article

It is my pleasure to offer the Agile community a new resource, an Agile Forum. I'm hoping it will be a brand-neutral, consultant-neutral place, open to and shared by everyone who is interested in advancing him- or herself in Agile, or in bringing Agile to the world. I'm inviting you to help make it a place you'd like to be.Lire l'article

The code is beginning to ask for some help. We're processing a simple array of cells instead of an object, and the classes don't feel cohesive. Let's push some methods off to new classes and see what happens.Lire l'article

A number of people on the tdd list have reported having a lot of fun TDD programming the game of Sudoku. I've not played the game, though of course I've tripped over the piles of books in the bookstores and at the airport. But discussion of the thing makes it sound like it might be fun to TDD on it, as people are saying. Let's get started.Lire l'article

Isaac Gouy is a perenniel poster on comp.software.extreme-programming, where his primary focus has been to "debunk" Craig Larman's book, "Agile and Iterative Development: A Manager's Guide". He has written an article, and I have agreed, in a spirit of open discussion, to post it on XProgramming.com. Here it is. (Updated: a reply from Craig Larman.)Lire l'article
