Understanding Successor Activities in Project Planning & Scheduling
In the realm of project planning and scheduling, understanding the relationship between activities is crucial for successful execution. One key concept in this regard is the Successor activity.
What is a Successor Activity?
A Successor activity, as the name suggests, is an activity that follows another activity. It's dependent on the completion of a Predecessor activity. This dependency creates a chain of tasks that need to be completed in a specific order.
Examples:
- Building a House: Before you can start painting the walls (Successor), you need to finish plastering them (Predecessor).
- Developing a Website: You can't launch the website (Successor) until you've finished coding and testing it (Predecessor).
- Launching a Product: You need to complete the marketing campaign (Predecessor) before you can officially launch the product (Successor).
Types of Successor Dependencies:
There are four main types of dependencies between Successor and Predecessor activities:
- Finish-to-Start (FS): The most common type, where the Successor activity can only start after the Predecessor activity is finished.
- Start-to-Start (SS): The Successor activity can start at the same time as the Predecessor activity, but cannot finish before the Predecessor.
- Finish-to-Finish (FF): The Successor activity can only finish after the Predecessor activity is finished.
- Start-to-Finish (SF): The Successor activity can only finish after the Predecessor activity has started. This is the least common type.
Why are Successor Activities Important?
Understanding Successor activities is crucial for several reasons:
- Efficient Scheduling: It allows you to create a realistic and efficient project schedule by ensuring that tasks are completed in the right order.
- Resource Allocation: Knowing the dependencies helps allocate resources effectively and avoids bottlenecks.
- Risk Management: Identifying potential delays due to dependencies can help proactively manage project risks.
- Communication: Clearly defining Successor activities ensures that everyone on the team understands the workflow and their individual responsibilities.
Software Tools for Successor Activity Management:
Many project management software tools, like Microsoft Project, Jira, and Asana, allow you to define and manage Successor activities. These tools often use a visual representation like Gantt charts to depict the dependencies and create a clear project roadmap.
Conclusion:
Defining and managing Successor activities is essential for effective project planning and scheduling. By understanding the different types of dependencies and utilizing appropriate project management tools, you can ensure smooth project execution and achieve your desired outcomes.

Exercise: Successor Activities in a Bakery
Scenario: You are the manager of a bakery that's launching a new line of chocolate chip cookies. The following tasks need to be completed:
- Order ingredients: Flour, sugar, chocolate chips, etc.
- Prepare the dough: Mix ingredients and knead the dough.
- Bake the cookies: Place the dough on baking sheets and bake in the oven.
- Cool the cookies: Let the cookies cool on a wire rack.
- Package the cookies: Place cookies in bags or boxes for sale.
- Display cookies in the shop: Arrange the packaged cookies for customers to purchase.
Task:
- Identify the Successor activities for each task, and specify the type of dependency (FS, SS, FF, or SF).
- Create a simple Gantt chart to visually represent the sequence of activities. You can use a basic table format.
Hint: Think about which tasks must be completed before others can begin.
Exercice Correction
