Mandatory Dependencies (also known as Hard Logic Dependencies) are a type of dependency in project management that requires one task to be completed before another can begin. This type of dependency is usually used when the tasks are related and must be done in a specific order.
A common example of a mandatory dependency is when building a house. The foundation must be laid before the walls can be built, and the walls must be built before the roof can be installed. Without completing each task in the correct order, the project cannot move forward.
Mandatory dependencies are important for ensuring that projects are completed on time and within budget. By understanding which tasks must be completed first, project managers can plan accordingly and ensure that resources are allocated properly. Additionally, mandatory dependencies help to identify potential risks and issues that may arise during the course of a project.
