In project management, which term is used for infrastructure or legal prerequisites influencing task execution?

The term used for infrastructure or legal prerequisites influencing task execution is referred to as "Mandatory Dependencies." These dependencies are conditions that are necessary and cannot be changed or avoided; they are about the fundamental requirements that must be met to allow a project to proceed. For instance, if a project requires a permit to legally begin construction, this becomes a mandatory dependency—it's a legal condition that must be satisfied before the project can continue.

Mandatory dependencies often arise due to regulatory requirements, contractual obligations, or the need for specific foundational tasks to be completed before subsequent tasks can be started. Understanding these dependencies is crucial for effective project planning, as they directly impact the timeline and resource allocation of the project.

Other terms like internal dependencies refer to relationships among tasks within the project that are based on the project’s internal processes, while external dependencies involve relationships with factors outside the project’s control, such as supplier timelines or regulatory decisions. Concurrent activities encompass tasks that can happen simultaneously but do not specifically relate to mandatory requirements. Thus, recognizing mandatory dependencies is essential for ensuring compliance and the overall success of project management efforts.
