Large organizations often struggle with IT development, and one of the main reasons is the “Dead Sea effect”. In this analogy, talented and effective IT engineers are like water that evaporates from the Dead Sea, leaving behind the less talented and effective engineers. These engineers are less likely to leave the organization due to the difficulties and problems that come with working in a large organization. This effect is self-reinforcing, making it harder for organizations to attract and retain talented engineers. However, it is important to note that not all IT departments experience this effect, and it is a result of various factors such as hiring processes and leadership.
