What is a downside of having multiple Development Teams working in the same codebase?

Having multiple Development Teams working in the same codebase can lead to significant coordination problems. This situation arises because when multiple teams are contributing to the same codebase, they must consistently align their efforts, manage dependencies, and avoid conflicts that can occur when merging code changes. These coordination issues can manifest in various ways, such as overlapping work, integration difficulties, and challenges in maintaining consistent coding standards.

Additionally, as teams may have different approaches to problem-solving or varying levels of understanding regarding the codebase, this can exacerbate the potential for miscommunication and errors. Therefore, while working in a shared codebase can present opportunities for collaboration, the inherent complexity and need for synchronization mean that coordination becomes a critical challenge that must be actively managed to ensure smooth progress and maintain code quality.
