Why is it best practice to work in Scoped applications?

Scoped applications are designed to encapsulate customizations and functionality within a defined boundary, which inherently protects the application from unintended interactions with other applications in the ServiceNow environment. This isolation is crucial because it mitigates the risks of conflicts that may arise when multiple applications try to modify overlapping components, data structures, or resources. By working within a scoped application, developers ensure that their changes and configurations are contained and safeguarded against inadvertent damage or interference from other applications, thereby maintaining the integrity and reliability of the custom application.

In contrast, while factors such as visibility, collaboration, and access to resources are important in an application development context, they do not specifically address the core concern of protecting applications from outside influences. Working in a scoped application is primarily about safeguarding development efforts, which is why it is regarded as a best practice.
