SOA for the rest of us

Earlier this year I wrote an article to introduce service-oriented architecture to non-technical people. It was published in the May 2007 issue of Better Software magazine. The kind folks at Better Software have allowed me to provide a PDF version of the article, complete with retro 1950s graphics. You can also read it as a […]

Introducing rbehave

rbehave is a framework for defining and executing application requirements. Using the vocabulary of behaviour-driven development, you define a feature in terms of a Story with Scenarios that describe how the feature behaves. Using a minimum of syntax (a few “quotes” mostly), this becomes an executable and self-describing requirements document. BDD has been around in […]

Outcomes over Features – the fifth agile value?

I’ve been having difficulty recently with a trend I’m seeing on projects. What happens is this: we (an agile development team) engage with a client for a short period – typically 2-4 weeks – to investigate how we might work with them to solve their problem. During this period, we drive out lots of stories, […]

Article: Introducing Behaviour-Driven Development

At the beginning of this year I wrote a feature article for Better Software magazine, which was published as “Behavior Modification” back in March. The article is now available on my site. It gives an overview of behaviour-driven development, from its origins as a coaching aid for TDD through to its current form as a […]

There’s more to BDD than evolving TDD

Behaviour-driven development started life as an NLP exercise to stem the abuse of the word “test” in “test-driven development”. Since then it has grown into a respectable and proven agile methodology (with a small “m” of course). Dave Astels, the award-winning author, was an early adopter of BDD and has been instrumental in raising its […]

What’s so hard about Event-Driven Programming?

I was lucky enough to attend the Software Architecture Workshop in Cortina recently. It was a three day workshop based around the idea of Open Spaces, which involves handing the asylum keys to the inmates and seeing what happens. I convened a session called “What’s so hard about Event-Driven Programming?” to explore the experiences of […]

BDD with intent

Charles Simonyi introduced himself at a recent workshop with the words: “I was at Xerox PARC in the 70s, Microsoft in the 80s, and working on intentional software in the 90s”. He wasn’t showing off, he was just there. He pioneered WYSIWYG, created Microsoft Word, Excel and Access (as a data visualization tool), championed OO […]
