7. Complexity

Many people have heard of Moore’s Law, which but have you ever heard of Glass’ Law? This rule says that for every 25 percent increase in a system’s functionality, there is a 100 percent increase in complexity. Code is getting bigger and more complicated. Running Microsoft on VMware, for example, entails over 100 different performance and capacity settings, resulting in millions of possible combinations of these settings. According to Paquet, there’s no push in the industry to make things simpler.

Why is that bad? When you make a system more complex, the cost of running and maintaining it inevitably goes up. And the quality of service goes down. According to Paquet, a reduction in system complexity has an incredible return on investment. In the next years, companies should focus on making simplicity a priority.
