Understanding Early Start and Early Finish

Before delving into the calculations, it is essential to have a clear understanding of what early start and early finish mean in project management. Early start refers to the earliest possible time a task can start without delaying the project’s schedule. On the other hand, early finish denotes the earliest possible time a task can be completed.

These calculations are essential in project scheduling as they help identify the critical path, which is the sequence of tasks that determines the project’s overall duration. By accurately calculating the early start and early finish for each task, project managers can identify which tasks are crucial for completing the project on time and prioritize them accordingly.

Step-by-Step Guide to Calculate Early Start and Early Finish

To calculate the early start and early finish of a task within a project, follow these steps:

1. Identify the predecessor tasks: Start by identifying all the tasks that must be completed before the task in question can start. These tasks are called predecessor tasks and are crucial in determining the early start and early finish.
2. Determine the earliest possible start: Once you have identified the predecessor tasks, determine the earliest possible start time for the task in question. This can be done by taking the maximum early finish time of all the predecessor tasks.
3. Calculate the duration: Determine the duration of the task, which is the estimated time required to complete it.
4. Calculate the early finish: Add the duration of the task to its early start time to get the early finish time. This will be the earliest possible time the task can be completed.
5. Repeat the process: Repeat steps 2-4 for each subsequent task in the project, adjusting the early start and early finish times as you go along.

Example of Calculating Early Start and Early Finish

To illustrate the calculation process, let’s consider a simple project with three tasks:

• Task A: Duration – 2 days, Predecessor tasks – None
• Task B: Duration – 3 days, Predecessor tasks – Task A
• Task C: Duration – 4 days, Predecessor tasks – Task A, Task B

Using the step-by-step guide outlined above, we can calculate the early start and early finish for each task:

• Task A: Early Start – 1, Early Finish – 2
• Task B: Early Start – 2, Early Finish – 5
• Task C: Early Start – 5, Early Finish – 9

These calculations allow project managers to identify the critical path and ensure the smooth execution of the project. By understanding the early start and early finish times for each task, project managers can make informed decisions regarding resource allocation, task dependencies, and project scheduling.
