Four types of task dependencies

Four types of task dependencies


"Nothing is particularly hard if you divide it into small jobs."
                                                                                                                 - Henry Ford

Projects, small or large, are driven by simple work units called tasks. Monitoring standalone tasks might look simple but as the workflow becomes elaborate, tasks may start relying on one another. In project management, this relationship between tasks is termed as "Task Dependencies".


Dependency between tasks arise due to resource constraints and logical factors. They are further classified into four types, namely, 

  • Finish-To-Start (FS) : The successor can't begin until the predecessor finishes. 
  • Start-To-Start (SS)  : The successor can't begin until the predecessor begins. 
  • Finish-To-Finish (FF)  : The successor can't finish until the predecessor finishes.
  • Start-To-Finish (SF)  : The successor can't finish until the predecessor begins.

Let us understand better by applying the types of dependencies in a real-time business scenario. Consider an industrial task, like coffee processing. It begins with the harvest of coffee beans. Once harvested, the coffee beans must be dried.

 

Drying the coffee beans cannot start until harvest is completed - Finish-to-Start

 

Once the harvested beans start to dry, grading can be initiated - Start-To-Start 

Later the beans are roasted to develop the flavor before being packaged into a final product.

 

Coffee packets cannot be filled until the roasting is done - Finish-To-Finish

 

Final packing cannot be completed until the packets are sealed - Start-To-Finish


We support all the four types of dependencies now. You can discover the dependent avenues in your business, connect them together, analyze the type of task dependency, and view their progress using Gantt charts.   


Hope you find our new feature helpful! For more information on task dependencies, take a look at our help guide. Learn more about our latest updates. For any suggestions or queries, reach us at support@zohoprojects.com .

    • Tip: How to print the Gantt View

      Though we move from the traditional project management system (using papers) to an online project management system, we still prefer to have a printed copy of the activities/tasks that are to be done in the project. This way, we can carry the to-do lists with us for the meetings and refer when we are offline. The print option, available at the right side of the page, allows the users to print the project information across all the modules. However, this option failed to print all the tasks & milestones

    • Task Inline Editing Enhancement

      Hi All, Today, we have made an enhancement in task inline editing. In 4.0, task edit is moved in a single screen in a pop-up. We designed this in-order to make the task edit across the product to be the same. Let it be in Feeds, Tasks & My Tasks tab, Calendar & My Calendar tab, a click on the task title will open the popup and user can edit the values. Customers pointed us the inline editing was very useful to them & how much they miss that in 4.0. Based on the feedback, we have rolled out this enhancement.
