How to bring your project to mind with PERT charts
If you read this material - there are probably two reasons for this:
- You are looking for the optimal project management solution that needs to be completed by a certain date.
- You are looking for a definition of the abbreviation PERT.
In any case, you are in the right place. We want to share the main advantages of the project evaluation and analysis technique and find out what PERT is all about.
The PERT chart is a multi-purpose project management tool that graphically displays the timing and progress of project tasks.
PERT (from the English Program Evaluation Review Technique) is a technique that helps identify and analyze tasks and goals. Many companies around the world use this time management technique to speed up and improve their business processes.
The PERT diagram formula was developed and described in 1958 by order of the US Navy Special Projects Unit for a missile system project.
These diagrams consist of circles or rectangles (nodes), which are key milestones in the project. Lines or vectors that define different tasks connect nodes.
When an arrow is drawn from task A to task B, this means that task A must be completed before task B. You can create parallel tasks that can be located at the same stage, but on different task lines. They should not depend on each other.
The diagram represents the events that should be implemented as part of the project.
Typically, a chart contains a horizontal chart with units (days or weeks).
The chart also displays a critical path with sequences of tasks that need to be carefully managed to complete all goals on time.
To understand how this works, you can select any chart template for the assessment and analysis technique and consider your case on it. For example, a template created using the Edraw Max program:
Here you can create clear graphics using the built-in symbol elements. This template consists of a legend, two forms of tasks, connectors and conclusions.
Here is an example illustration of a PERT chart that demonstrates how to break a garden with a chart:
We have selected examples of three tools that will help you build PERT daagrams.
In the program you can find a complete set of functions and design options to implement your tasks. It is suitable for Windows, Mac, and Android and allows you to use dozens of PERT chart templates for common tasks. You can choose one of the examples similar to your project and adapt it.
Lucidchart is also available on Mac or Windows. The service offers an unlimited selection of settings and powerful features. Here you can find a detailed description of PERT diagrams and the Lucidchart library for working with project assessment and analysis techniques.
It is also easy to create a professional PERT chart in this program. Using convenient service tools, you can create online diagrams for tasks, work schedules, the critical path method, work with the task hierarchy according to the structure of WBS, etc.
The advantages of PERT schedules are obvious, but project managers should also pay attention to some of the shortcomings that may become an obstacle to project implementation.
Advantages of PERT technology for project managers:
Вот, к примеру, преимущественные отличия PERT от метода критического пути CPM:
Некоторые недостатки PERT:
Метод PERT требует расположения активностей во временной последовательности. Процесс анализа носит субъективный характер, именно поэтому эти схемы не могут точно оценить стоимость и время.
Технология определяет потребности в рабочей силе и материально-техническом оснащении для видов активностей в проекте. Тем не менее, PERT — это прежде всего метод, сфокусированный на работе с временем.
Метод требует детального исследования и изучения замечаний от многих людей.
PERT считается достаточно дорогой техникой из-за трудоемкого характера работ.
Graphs and charts, special programs and applications are just tools that help you manage your projects and make them better. But you should always be ready to apply relevant and new options to achieve maximum results.
Gantt charts and PERT charts are useful tools for visualizing goals and objectives. Both structures can be created using software applications. The choice is yours, a lot depends on the specifics of the project.
The main difference between these tools is in the way they demonstrate and display information.
Project management with Gantt charts is based on a bar chart format. This helps keep track of the percentage of work completed for each task. PERT offers a network model.
It is very important for project managers to correctly assign tasks and to be sure that the project will be completed by the deadline. Gantt charts focus on the percentage completion of each task. The PERT technique does not provide such data. According to this indicator, Gantt diagrams look more convincing.
In addition, Gantt charts are preferable for projects with a small number of interrelated tasks.
Summarizing all of the above, we want to note that the diagrams drawn up by the technology of assessment and analysis of PERT projects can become an effective tool in your activity. It is best to compare them with the more popular Gantt charts and choose the best option for your projects.

Elements of PERT Project Evaluation and Analysis Technique
The diagram represents the events that should be implemented as part of the project.
- Arrows indicate directions and indicate the flow of events that should occur.
- Dotted lines represent fictitious activities that are elements located in a different path.
- The numbers assigned to each task govern them.
Typically, a chart contains a horizontal chart with units (days or weeks).
Steps to Create a PERT Chart
- Make a list of levels and stages of the project, determine the time required to complete each event.
- Add dependencies to create a link between events.
- The lines show the time each event takes.
- Each line in the diagram should come to a step that is associated with the completion of the event.
The chart also displays a critical path with sequences of tasks that need to be carefully managed to complete all goals on time.

PERT Design Charts: Pros and Cons
The advantages of PERT schedules are obvious, but project managers should also pay attention to some of the shortcomings that may become an obstacle to project implementation.
Advantages of PERT technology for project managers:
- Using charts, project managers can evaluate and analyze the time and resources needed for a project.
- Charts provide the ability to track and manage the assets needed at any stage of production.
- Chart analysis contains data and information from various departments. This helps to optimize communication during the course of the project, identify responsible parties within the company and distribute responsibility.
- The technique helps managers do what-if analysis. This analysis reveals the opportunities and uncertainties associated with the project and helps to minimize unpleasant surprises and losses. What-if also highlights all risky events and stages that require careful analysis and monitoring during the implementation of the project.
