What is Mandatory Dependency?

In project management, a Mandatory Dependency is a critical step that must occur before another, comparable to how you must finish building the foundation of a home before putting up the walls. It’s a task connection in which one work must be accomplished before the next can begin, much like a fixed rule or requirement. Consider it a tight sequence in which Task B cannot begin until Task A is completely completed, with no exceptions. This form of dependence is vital, and the job sequence is defined, guaranteeing that the project develops in the correct order and that everything goes smoothly according to plan.
