We will talk about a new development technique called WDD or Worries Driven Development.
You might know another couple of *DD techniques: TDD and DDD but they are by far less powerful than WDD.

TDD or Test Driven Development has been invented by Ken Beck (@kentbeck). As Wikipedia states “is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass that test and finally refactors the new code to acceptable standards”.

DDD or Domain Drive Design is a little more recent, especially it’s hype, and as Wikipedia says “is an approach to develop software for complex needs by connecting the implementation to an evolving model.The premise of domain-driven design is the following: Placing the project’s primary focus on the core domain and domain logic; Basing complex designs on a model of the domain; Initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems.” In Italy Alberto Barndolini (@ziobrando) is really good at it!

WDD is more powerful because it works at a deeper level. It acts at the level of motivations. We tend to do what we do for one of two reasons: to seek pleasure or to avoid pain.
Now our culture tend to push us to the ‘avoid pain’ side so we tend to use it more often as a motivation to do what we do. So what’s more relieving than solving a problem to ‘avoid pain’?
That’s where WDD come from: we do what worries us. Or better we do, schedule, put in priority what can have consequences that can worry us.
So the algorithm is: if you don’t have it, create a problem, throw it in the future, communicate it so that everybody can be worried. Now you are ready to make a lot of overtime to solve it to ‘avoid pain’.

The secret? WDD is not that new: it is quite often used as a primary development paradigm in many offices of medium-big corporations. And it works …. maybe.
