An overcomplicated project increases development and maintenance time. We need some metrics for reducing the complexity of the existing code base. However, if we can make complexity visible, it will be much easier to work with it.
Sun Tzu said in The Art of War: "If you know your enemy and know yourself, you have nothing to fear from the outcome of a hundred battles".
In this talk we will talk about how to measure project complexity and how to visualize this complexity for successful follow-up actions to reduce complexity.
In each part of the talk, examples of complexity measurements in well-known OS projects will be given. Thanks to visualization tools we will be able to take a closer look at our enemy.
