Every project is made up of tasks, and the sequence of those tasks are often of the upmost importance.<\/span> Certain tasks can’t begin until another one has finished, and vice-versa. In order to ensure that tasks are done in the correct order, project managers employ the use of Gantt charts and Gantt chart software<\/a> to track the dependencies between their project’s tasks.<\/p>\n

In order to talk about Gantt chart dependencies, though, we must first talk about Gantt charts.<\/p>\n

What Is a Gantt Chart?<\/h2>\n

Gantt charts<\/a> are a well-known project management chart. Gantt charts are visual tools created during the project planning phase and are used to show a wide range of project data as simply as possible with horizontal bars.<\/p>\n

This horizontal bar chart is the easiest way to see how projects are scheduled over time. This includes which tasks must be completed, how long those tasks should take, who is responsible for which tasks, etc. Gantt charts also allow you to create and view milestones.<\/p>\n

ProjectManager<\/a> allows you to create a Gantt chart in minutes. And unlike other Gantt chart software, it features all four different types of Gantt chart dependencies, so you can quickly build a schedule and stick to it. Start hitting your milestones with a free trial of ProjectManager today.<\/p>\n\"Gantt<\/a>\n

Gantt Chart Dependencies<\/h2>\n

Most of us understand dependencies in a broad sense: activities can be interrelated and influenced by one another. This holds true for Gantt chart dependencies. Also called a task dependency, a Gantt chart dependency refers to how project tasks are related. In most projects, there will be multiple tasks taking place at once or in quick succession. When this is the case, these tasks have an effect on one another and are known as Gantt chart dependencies.<\/p>\n

On the Gantt chart itself, each task is represented as horizontal bars which show task duration. The longer the bar, the longer you have to complete the task. But, each individual task does not exist in a vacuum and is dependent on another. Each shares a unique relationship. Even the very first task in a project shares task dependencies with others. These Gantt chart dependencies are represented by lines between the horizontal bars.<\/p>\n

Four Types of Gantt Chart Dependencies<\/h2>\n

Gantt charts are an excellent way to create and see tasks, but first you must know exactly how your tasks are related and how this will be illustrated. This is a critical part of task management. Depending on the task dependencies, the tasks themselves will look different on the Gantt chart. When you don\u2019t know what these variations look like and what they mean, Gantt charts quickly go from being helpful to seeming jumbled and confusing.<\/p>\n
