Knowing what a CPM chart is and how it works will therefore help you to better manage your budgets and resources, which in turn will translate into more savings and more precise control over costs. Read on to find out how to make a CPM chart!
What is the CPM (Critical Path Method) diagram?
The CPM diagram is a technique used in project management to identify the sequence of key activities that will determine the total time commitment required for each of them . This is called the 'critical path' , and its importance lies in the fact that any delay in one of these tasks will affect the entire project schedule.
CPM is especially useful in large, complex projects, such as construction or software development, where each task depends on the completion of others. It differs from PERT in that it takes into account the costs of each task and uses more defined time frames. Did you know this difference between CPM and PERT?
How to use it in project management
How the CPM chart works
The CPM diagram works by identifying all the tasks required to complete a project and estimating the duration of each of them . After this, dependencies between the tasks are assigned and a network diagram is created in which the activities are represented by nodes and the connections indicate the sequence.
The earliest start time (ES) and latest finish time (LF) are calculated uk business email list by traversing the diagram from left to right and back again. This establishes the critical path , which is the sequence of activities with no margin for delay.
All of this, combined with tools such as those included in the Office 365 solution that we offer at GoDaddy, makes this methodology help managers focus on the most important tasks to avoid project delays.
Benefits of using the CPM chart in project management
Using the CPM diagram in project management offers a number of advantages for those who need to optimize time and resources, and the following are some of the most interesting ones.
It allows you to calculate the exact time that each task will take , which facilitates scheduling and reduces the possibility of incurring delays.
It helps to prioritize tasks and resources that require more attention , which helps to avoid bottlenecks.
By visualizing the entire schedule, it is possible to identify risks or delays before they occur and, therefore, implement solutions to get ahead of them .
It facilitates the compression or acceleration of tasks , in case delivery times need to be shortened.
Furthermore, and this is important, the control it provides also achieves better budget management .
Steps to create a CPM chart
Creating a CPM chart requires a structured process that allows you to organize all the project activities and their dependencies. It can be summarized in a few steps.
Identify all tasks necessary to complete the project.
Define which tasks depend on others to be completed and estimate the duration of each of them.
Draw a network diagram with nodes connected by arrows , indicating the sequence of activities.
Identify the earliest and latest possible start and finish times for each task.
Calculate what sequence of tasks must be completed on time , to avoid delays throughout the project.
