If you’ve ever struggled through mapping project work or keeping track of dependencies, we have actually the perfect solution for you. 

A PERT chart, likewise known as a PERT diagram, is a tool supplied to schedule, organize, and also map out tasks within a project.

You are watching: The first step in the creation of a pert/cpm chart is to ____.

PERT stands for program evaluation and also evaluation approach. It offers a visual representation of a project's timeline and also breaks down individual tasks. These charts are similar to Gantt charts, however structured in different ways. 

This diagram consists of a few steps to obtain you from a project begin date to finish day. In this write-up, we’ll cover the 5 procedures, show you an instance, and explain how to properly usage a PERT chart to your advantage. 

How a PERT chart works

A PERT chart functions by visually representing a project’s jobs and also the dependencies associated to each one. You can usage one to create an initial schedule and also approximated timeline to share via project stakeholders prior to the project actually begins.

Creating a task roadmap such as a PERT chart deserve to help you attain several job planning activities, including:

Getting schedule and timeline signoff from leadership

Communicating task missions to stakeholders

Visually mapping out a complex project

Estimating the time needed to finish individual tasks 

In order to make the many of your PERT chart, you must first understand the measures necessary to complete one and how to visually map out your diagram.

How to make a PERT chart

To develop a PERT chart, follow the five actions of the procedure lifecycle, which includes every little thing from identifying jobs to managing project completion. 


1. Identify task tasks

The first action in creating a effective PERT chart involves identifying and collecting essential task information and jobs. You deserve to begin the project planning phase equivalent to how you’d frequently begin the initial task administration phase. This can include:

Early planning ensures that you’re ready to defined dependencies and connect work in the time of the following phases.

2. Define task dependencies 

A job dependency is a task or milerock that counts on one more job to be completed before the task at hand deserve to be started. This is sometimes referred to as a logical connection and also is regularly provided in a work-related breakdown structure. 

Creating dependencies have the right to assist you appropriately track work-related, ensure tasks are completed, and develop clear communication. For complicated tasks, arrangement timelines and also job duration properly ahead of time.

In a PERT diagram, dependencies are visualized by connecting and numbering jobs. While not as in-depth as other techniques choose a job-related breakdown structure, it helps to show a high-level visualization of work and the occupational required to finish them.

3. Connect project tasks

Once task dependencies have been produced, you can job-related on developing your PERT chart by connecting task tasks to one another. These relationships consist of arrows, which reexisting tasks, and nodes, which recurrent events or turning points. 


For example, place parent occasions within your nodes (stood for as numbered circles or squares) and also attract task arrows to reexisting the dependencies essential to complete your events. 

This layout offers a straightforward job framework that, while not overly particular, is easily comprehensible for project stakeholders. 

4. Estimate project time frame

Now it’s time to estimate your in its entirety task time frame utilizing the instrumental course technique (CPM) and also the PERT formula. The important path is the longest sequence of tasks that need to be completed to effectively end up a project. 

The objective is to discover the longest route that will certainly take the most time to complete in order to estimate the shortest all at once task duration. Time approximates deserve to be calculated based upon the following:

Positive time: The minimum amount of time required to accomplish a job.

Pessimistic time: The maximum amount of time essential to attain a task. 

Many most likely time: The ideal estimate of just how lengthy it will most likely take to accomplish a job.

 You can use the PERT formula to calculate the intended duration of a job and also completion time using: (O + (4 × M) + P) ÷ 6. This deserve to be measured by minutes, hrs, days, or also weeks. 

For instance, if the optimistic time is 30 minutes, the pessimistic time is 60 minutes, and also the the majority of likely time is 45 minutes, the PERT formula would certainly be: (30min + (4 × 45min) + 60min) ÷ 6 = 45 minutes. 

Once you’ve calculated the meant time per job, you can then add each of the approximates of your crucial path together to gain an average job timeline.

5. Manage job progress

The last step in producing a PERT chart is to manage task progress to task completion. This have the right to be done by closing dependencies and also mitigating issues along the way till all jobs are completed. 

Remember that a PERT diagram have to be updated throughout the task as transforms occur. This might be paired via a adjust control procedure, which helps map and also interact project alters. 

Once all tasks within the project have actually been completed, you have the right to archive products in a mutual space to be referred to in the future if needed.

PERT chart example

Now that you understand the 5 actions of a PERT chart, it’s time to develop among your very own. Because all diagrams differ depending upon the intricacy and also time structure of a provided task, yours can look slightly various. 

To start your chart, start by:

Drawing your numbered nodes: Remember, these are the parent jobs of your job which, once completed, will make up the task at hand also. Your diagram may have actually any number of tasks, but 10 is an excellent number to begin via. 

Connect your nodes to tasks: Draw arrows to represent task dependencies. These jobs are what should be done for the occasions to be completed. Your diagram must have a clear beginning and end, though the middle might look more facility. 

Here’s an instance of what your PERT chart must look like:


Here is a failure of prevalent terminology you may incorporate in your PERT chart and also the interpretation for each:

Nodes: Nodes recurrent job occasions. These events are the large components that consist of your task. For instance, as soon as launching a webwebsite architecture, a node could reexisting a new logo design.  

Tasks: Your work are what have to be completed in order for your nodes to be applied. For example, a job could recurrent developing three logo design mockups. 

Dependencies: A dependency is once a task is associated to an additional job. These work depend on one an additional and one cannot be completed without the other. 

Dependencies without resources: A dependency without resources is one that, while connected to an additional, doesn’t have tangible jobs that have to be completed. For example, while a product launch and landing web page might be associated, no one task is connected to each. 

PERT charts have the right to be developed using a variety of devices, including task administration software. Tools have the right to assist you appropriately setup, visualize, and set up task dependencies and reminders in order to track job development and also easily spot bottlenecks.

When to use a PERT Chart

Project managers use PERT charts to evaluate and finish a given task. But via so many other techniques to pick from, just how does a PERT diagram compare? 

For starters, a PERT chart is an excellent method when you’re looking to evaluate the timeline, sources essential, and also a project’s important course. Let’s look at each of these a little closer.

To identify the crucial path: One of the crucial attributes of a PERT chart that sets it acomponent from various other approaches is its capability to identify a project’s critical path. This is important as soon as visualizing the as a whole timeline of a job. 

To evaluate resources: With the distinct attributes a PERT chart offers, you deserve to easily screen which tasks require resources and which don’t. This saves both you and project stakeholders time by having actually that information upfront and accessible. 

To estimate time: Because a PERT chart evaluates both individual job duration and in its entirety task duration, it’s a great tool when you must understand also the supposed timeline throughout the initial job planning phase.

Overall, developing a PERT chart is a good alternative for an easy task plan that have the right to conveniently be mutual with team members. Use this chart to quickly share sources and also timelines.

PERT chart vs Gantt chart

PERT charts and also Gantt charts are frequently confused, though they have a couple of crucial distinctions. Not just do they differ in their visual appearance, but they additionally carry out various attributes depending on what your team requirements. 


Here are a couple of crucial attributes to note once deciding on which one is ideal for you:

PERT charts are flowcharts while Gantt charts are bar graphs: One of the best distinctions is their visual layout. While Gantt charts take on a standard bar chart technique, PERT charts are less structured in appearance and take on various layouts depending upon the job.

Gantt charts sell company while PERT charts offer customization: Gantt charts are more structurally arranged. On the various other hand, PERT charts allow easy layout customization which is better for high-level job needs. 

PERT charts have the right to be provided prior to the job begins: Because PERT charts market an easy project arrangement and timeline layout, they’re frequently supplied as visual guides in the time of the task kickoff. Project supervisors then usage another method, favor a work-related breakdown framework or Gantt chart, to especially map project jobs and dependencies. 

In basic, Gantt charts are even more well-known for mapping out task tasks throughout the project lifecycle while PERT charts are renowned for time mapping in the initial project steras. They have the right to be used independently or together to develop a substantial arrangement.
