Why must a project in Copado be linked to a pipeline?

Linking a project to a pipeline in Copado is essential primarily because it allows users to identify the target environment for deployment. This connection streamlines the deployment process by ensuring that changes are aligned with specific environments, whether that be production, staging, or a testing environment. By defining this target, teams can effectively manage where updates and changes will be deployed, minimizing the risk of errors and ensuring that deployments are planned and executed methodically.

The other options provided, while they may touch on aspects of project management and user story tracking, do not capture the fundamental reason for linking a project to a pipeline as accurately as identifying the target environment. The tracking of user stories, team collaboration, and project documentation are important aspects of project management, but they revolve around broader project execution rather than directly influencing the deployment environment, which is a primary function of the pipeline linkage.
