Task Dependencies - FS, FF, SS, SF - IMPORTANT

Lecture description

In the previous exercises, we have seen how to create tasks in Project. We have seen different types of tasks, task modes, different ways of creating tasks and different ways of organizing them. 

Almost ALWAYS, the tasks in a project are related to each other, and the relationships between them drive the schedule for the project. You will find very few tasks in isolation, if any at all. 

The relationships between the tasks are called "task dependencies" or "task links".

Instructor: In the previous exercises we have seen how to create tasks in project. We have seen different types of tasks, task modes, different ways of creating tasks and different ways of organizing them. Almost always the tasks in a project are related to each other and the relationships between them, drive the schedule for the project. You will find very few tasks in isolation, if any at all. The relationships between the tasks are called task dependencies or task links. Project offers four kinds of task dependencies. They are finished-to-start, FS, start-to-start, SS finish-to-finish, FF, and finally start-to-finish, SF. We will pick up from where we left in the previous lesson and the next step in building the project schedule is to create dependencies that reflect your actual project scenarios. Let us first see the simplest way in which to create a dependency. First, select the tasks to be linked. The first two tasks get approval from board and directors and initiate a project are syntactically to be linked. I will set them both on the Task tab and in the schedule section, click this icon called link. The icon looks like a chain link and does precisely that. It creates a dependency between the first two tasks. You can see that in the Gantt chart here an arrow mark has appeared from the end of the first task to the start of the second task. Once you have created the link you can also see for the second task the start and finish dates have been automatically updated and they're in a light blue color visually it shows you what has changed. So in this case, the project initiation that is task two can only start when the approval is completed. That is task one. Let us now look at the other types of dependencies that project has to offer. To do that there is another view that Project provides us to conveniently set a task detail. First to select a task ID 4 like I have done, and click on the view tab. Now, you can see a checkbox here called as a details in this split view section. When you turn this checkbox on the task form split window opens up. This window can be toggled off or on from this check bar at any time by going to the details button as just now, I showed. If you get the resources and predecessors here, just right click and select predecessor and successor option. Before doing anything first to confirm that the name here resource plan for approval matches the task that you have selected. First confirm the name box that you're working on the correct task. Then in the successor name column click here to open a dropdown box with all the task names. Select ID 5 task "IT infra plan for approval" that is here. So what you're saying now is that this task is a successor for this task. And once that is done, we click on the type column to select the type of dependency link. I will select this start-to-tart-dependency, SS dependency. This is because these two tasks which require getting approval from two different departments can start together. Just to clarify for you, start-to-start dependencies are used when the second task in the relationship can't begin until the first task in the relationship begins also. Start-to-start dependencies don't require that both tasks start at the same time. They simply require that the first task has begin in order for the second task to also begin. Let us see the next type of dependency. We will link the next two tasks to demonstrate a finish-to-finish dependency. If one of your tasks can't finish until another one also finishes you can use a finish-to-finish dependency between them. Finish-to-finish dependencies don't require that both tasks be completed simultaneously. They simply require that the first task be finished in order for the second task to also finish. Similarly in the successor I am going to select electrical layout plan and select the type two finish-to-finish and say, okay. The second task can actually finish anytime after the first task finishes. Now we have linked these two tasks. The last type of link that we have to see is the start-to-finish, SF dependency. When you use this type of dependency, you are saying that the second task in the relationship can't to finish until the first task starts. This somewhat reverses the time order of the two tasks. You should not be using this dependency very often and you should carefully validate this type of link if you are ever required to use this type of a link. We have linked the last two tasks with an SF dependency and you can see how this looks now. Let us now take a moment to see all the links on the Gantt chart, the FS link, the SS link, the FF and finally the SF links. We will continue with this exercise in the next lesson where we will link the remaining tasks of this project. See you in the next lesson.
