The basics of PERT charts: What they are and how they work

Are you tired of missed deadlines, unexpected delays, and project oversights? Do you want to increase your project management skills so that you can stay on track, manage your resources more efficiently, and achieve your goals? If so, then it's time to learn about PERT charts.

What are PERT charts?

PERT, which stands for Program Evaluation and Review Technique, is a project management tool that was developed in the 1950s by the U.S. Navy. PERT charts are graphical representations of the tasks and activities involved in a project, along with their expected completion times and dependencies.

The purpose of a PERT chart is to enable project managers to plan, coordinate, and track the progress of their projects effectively. By identifying the critical path of a project – the sequence of tasks that determine the earliest possible completion time – PERT charts help managers to prioritize resources, allocate tasks, and adjust timelines to avoid delays and bottlenecks.

How do PERT charts work?

A PERT chart consists of nodes, representing each activity in a project, and arcs, representing the dependencies between these activities. Arrows connect the nodes, indicating the sequence of completion. Each node is annotated with its expected duration, and the critical path is identified by highlighting the nodes with the longest cumulative duration.

To create a PERT chart, you need to follow these steps:

1. Define the scope of the project - Identify the overall objective, the key deliverables, and the milestones.

2. Break down the project into smaller tasks - Divide the project into manageable units of work, such as research, design, development, testing, and deployment.

3. Sequence the tasks - Determine the order of the tasks, based on their dependencies and the critical path.

4. Estimate the time required for each activity - Assess the duration of each task, taking into account the resources, skills, and risks involved.

5. Draw the PERT chart - Create a graphical representation of the project's activities, dependencies, and timelines.

Benefits of using PERT charts

There are several benefits of using PERT charts in project management:

1. Better planning - PERT charts help project managers to break down their projects into smaller, more manageable tasks, and assign resources accordingly.

2. Improved coordination - By identifying the dependencies and timelines of each activity, PERT charts help project managers to coordinate the efforts of the team and avoid conflicts or delays.

3. Effective resource allocation - PERT charts enable project managers to allocate resources more efficiently, by identifying the tasks that require the most time, effort, or resources.

4. Risk management - PERT charts help project managers to identify potential risks or bottlenecks in the project, and take corrective action before they impact the project's success.

PERT chart examples

To give you a better idea of how PERT charts work, let's look at some examples:

1. Website development project:

In this PERT chart, the website development project is broken down into several smaller tasks, such as designing the user interface, developing the functionality, and testing the website. The critical path is highlighted in red, and the expected timelines for each task are shown on the nodes.

2. Product launch project:

In this PERT chart, the product launch project is divided into several phases, including product development, marketing strategy, and distribution. The critical path is identified by the dashed line, and the expected timelines for each activity are annotated on the nodes.

Conclusion

PERT charts are an essential tool for project managers who want to plan, coordinate, and track their projects effectively. By creating a visual representation of the project's activities, dependencies, and timelines, PERT charts enable project managers to prioritize resources, allocate tasks, and adjust timelines to avoid delays and bottlenecks.

If you want to improve your project management skills and achieve your goals more efficiently, then it's time to start using PERT charts. Visit pertchart.app to learn more about PERT charts and how they can benefit your projects!
