We are now ready to begin writing our first lines of actual production code. To assist us we have our acceptance tests that we need to pass, and the CRC-cards from last time. More importantly perhaps, we have access to those who can tell us what the acceptance tests really mean if we get confused, [...]
The team has identified the tasks for the first iteration and are about ready to go to work on it. Before we continue, we pause to have a quick design session where the major classes of the application are identified. The design session is done collaboratively with several, if not all, team members present.
For this [...]
After some time off I return to our XP simulation where I attempt to implement a little messaging application. For the iteration ahead there is only one story planned: “A user can send a text message to another user – the console version.” The story is estimated at 5 points. We have a good idea [...]
After the first iteration I have learned quite a few things about Ruby basics and the support for what I need to get started developing the application. Looking at the project whiteboard we now see that the next thing to do is to tackle the first user story – “A user can send a text [...]
I spent the first iteration investigating basic Ruby and the tools available for creating automated tests. I am nowhere near feeling confident in all aspects of the language or on all the intrinsics of the tools but I hopefully I have enough to get the story planned for the next iteration going.
Ruby has a unit [...]
Last time I did a rough estimation of all user stories supplied so far. In addition the iteration length was set to one week. This time I am going to plan the work for the near future. I may even come up with a rough estimate for the final release.

To throw some risk and uncertainty [...]
As an excursion in XP I am currently implementing a simple instant messaging application so that I can try out the mechanics of it’s practices. As I am alone on this I will not be able to take full advantage of some of the practices (it will be hard to pair-programming for one). The system [...]
Last time the customer brought the first approach user stories to the rest of the team. By just looking at them, a few things about the design could be inferred, but the team has not created any architecture or design for the application yet. That doesn’t mean that it is not there. It’s simply not [...]
As an exercise in the mechanics of an XP project I am creating an instant messaging application. I will attempt to pay attention to the different roles and act accordingly in the different stages of creating the application. My hope is that this can be compressed into a one or two day workshop on XP [...]
I have decided to experiment a bit with the planning aspects of Extreme Programming. I will do this as a one man project, at least initially, so I can explore at my own pace, the mechanics of the planning game and those of the practices that I can manage to use on my own.
I am [...]
