The Cost of Accidental Complexity in Development

In the beginning, IT teams often implement new features quickly, but over time, development tends to slow down. Accidental Complexity is a frequent culprit – this article explains its origins and how it can be mitigated. This article was originally published in German as a premium article on Golem.de in June 2023. It’s no secret that systems grow more complex over time, leading to longer development cycles. This is inevitable when dealing with inherently complex problems, known as Essential Complexity.

Two More Billion Dollar Mistakes

Hi, You might have heard that null was referred to by its creator, Tony Hoare, as the “billion-dollar mistake.” In 2009, he publicly apologized at QCon for taking the easy path in 1965 by inventing null: “I call it my billion-dollar mistake.

Hi, Do you know what Survivorship Bias is? […] According to Survivorship Bias, the probabilities of success are systematically overestimated because successful individuals or states are more visible than unsuccessful ones. ~ Wikipedia This cognitive bias is interesting because it affects us in development as well. For 15 years, I have been working mainly in small and medium-sized enterprises (SMEs), which are companies with up to 250 employees. Clearly, these are not large corporations.

Challenges in SMEs Are Similar

Hi, Currently, I am writing a new article for Golem.de. In this context, I have been reflecting on the similarities in software development in small and medium-sized enterprises (SMEs). The German Federal Statistical Office defines SMEs as companies with 10 to 250 employees and a turnover of less than 50 million euros. At first glance, this range seems very wide. Intuitively, one would expect the challenges and solutions to be very different as a result.
