The survey results highlight that professional developers spend around 30% of their average weekly work time on code maintenance, with a significant portion of this time related to the open source packages they use. The larger the development team, the more time is dedicated to code maintenance. On average, open source packages contribute around 25% of the total code maintenance workload, but there is significant variance in this figure. The most common open source maintenance tasks are improving, replacing, and keeping up with packages, often occurring together. This suggests that developers face challenges in maintaining their applications' dependencies, particularly when dealing with unmaintained or outdated libraries.
