Why Pair-Programming Works


Recently, I’ve given a short presentation about pair-programming and the stereotypes people show while pair-programming. As always when talking about pair-programming, there is a discussion how to sell it inside a team to peer developers or even worse to managers. Their killer argument is that two people in front of a single computer result in doubled effort needed to complete software.
Let my show you why this is wrong.

Structure your code by feature


cross-post from bbv blog
When software projects grow both in age and size the developers often struggle with the structure of the code. It gets more and more difficult to find the class you have to change for a new requirement. In this post, I’ll show you how we organize our code and how we derive our structure directly from the requirements.

Pair Programming Stereotypes


Over the last couple of years, I’ve done a lot of pair programming. Pair programming inside my team, at customer sites, in coding dojos and in my open source projects. Pair programming is really a great and effective experience when performed by an pair of developers knowing how to pair program. Unfortunately, you cannot just put two developers in front of a single computer and expect them to perform perfectly from the start. Pair programming has to be learned. Both developers need to learn the...

Different Flavours of Pair Programming


Pair programming – two developers working together at a single computer – can result in better software written faster, but only if you know what you do.
Pair programming is not just sitting together and code as you would when being alone. Unfortunately, this is what most developers practice – resulting in a painful and ineffective experience.
To get most out of pair programming, you first have to know your setup.

Presentation: Agile Code Design – how to keep your code flexible


These are the slides along with some comments from a presentation I gave lately in the bbv .Net System boot camp – the yearly education week of my division in my company. Once upon a time, Agile Software development came to our software development country. Like a monster, Agile software methodologies scared the hell out of us. Suddenly, we had to find ways how to build software so that we could keep up with the high rate of change, just-in-time requirements and a sacrificial offering – a...

16 ideas about what a Scrum Master can do to improve team performance


cross-post from bbv Blog
This is a list of actions that Scrum Masters at bbv Software Services AG have applied successfully in their teams to improve performance (= how much gets done in an amount of time). Please note that these actions were created to respond to specific problems found in real world projects. They may not be applicable in general in any situation.
I’d be happy to read your experiences and feedback in the comments section.

Variable prefixes


The idea of variable prefixes
The idea of prefixes on variable is “very” old. They are used to tell the developer what kind of variable he is using. The first prefix for example is m_ and the conclusion is this variable is a member. When I learned programming we had to give the developer more information in case of a member. Like the type of it like an integer became m_i.
