Overview

Dependencies influence the way the project must be undertaken. In this tutorial, we will learn about different types of dependencies in Project Management.

What is a Dependency?

A dependency is a logical relationship between tasks, activities or phases. Dependencies can be internal to the project or external to the project.

Types of Dependencies

There are four types of dependencies:

• Finish to Start( FtS)
• Start to Finish( FtF)
• Start to Start( StS)
• Finish to Finish ( FtF)
