What is PERT? How to use PERT in Project Management?

Project Management

Bring in your planner, organizer, and resource manager to collaboratively come up with a project plan, and you will have an amazing project plan. The primary objective of Project Management is to successfully complete specific project goals.

Project management can also be referred to as a study that is practiced to apply all the concepts and methodologies to minimize project time and maximize productivity.

Project tasks in an organization can be difficult to manage, so organizations hire project managers to manage, organize, schedule, and plan project tasks by team members and project milestones.

 

Concept of PERT in Project Management

As previously stated, the Program Evaluation and Review Technique (PERT) is a visual tool used in project management to design and organize project tasks. PERT in project management is a visual tool. The data and information after origination are displayed in the form of a chart.

A PERT diagram is basically used to schedule every task involved in a project in coordination. It also helps in tracking the real-time progress of the overall project.

In any project, irrespective of the size of the project, estimating the time required to execute the project is crucial to predicting and managing other aspects, such as resources and budget. Hence, using a PERT in project management helps in determining realistic estimations.

 

PERT charts

A flowchart is used to depict all the evaluated results. Descriptions of the details obtained using the Program Evaluation and Review Technique are called PERT charts.

What does PERT chart software contain?

The main components of the PERT chart software include

• Nodes: It refers to the task. Each node indicates the task name and may also display the task's duration.
• Arrows: It displays the tasks' order or direction as well as their interdependencies. Task A must be finished before Task B, assuming an array from A to B.
• Time Estimation: It gives you an approximate time needed to complete the task.
• Critical Path: It is the longest probable route that consistently yields the quickest project completion time.
• Milestones: Milestones are the major events or due dates in a project timeline.

It is a flowchart with nodes representing the events that indicate the initial and end stages or activities of a project task. The directional lines connecting the nodes indicate the tasks of the project, while the arrows show the hierarchical sequence of project activities.

This network diagram of tasks not only allows project managers to create an organized set of project schedules but also helps team members track project tasks. The main objective of a PERT chart is to represent an estimation of the project timeline and task duration and to identify task dependencies and critical paths.

These tools tend to behave more powerfully when combined with online project management tools. These help you make a schedule that updates in real time.

The workings of a PERT chart are very simple if you understand its outlines.

 

 

A PERT chart is made up of nodes and directional arrow lines. Nodes represent events in the project and are drawn with numbered circles or boxes. The arrows direct the flow of work along with the task that is to be completed before moving on to the next task.

A PERT chart is a visualization of project tasks and dependencies. This helps provide a framework for structuring project work. This helps provide a framework for structuring project work. Overviews of the tasks that must be marked as essential to be completed are also easy to estimate and provide to the team members.

A PERT chart can assist project managers in performing such tasks because the main goal of project managers is to design a project plan that can reduce unnecessary time and budget. 

 

PERT Charts vs Gantt Charts

Since PERT charts and Gantt charts serve their unique purposes, it is hard to decide whether to compare these two most-used and powerful tools.

The purpose of PERT in project management is to design a plan structure for the project that serves all necessary tracking details that explain to team members the priority of project tasks and allows project managers to track the progress.

A Gantt chart is basically used for constructing an ongoing roadmap for the project that will be assigned to a project team. This allows managers and team members to adjust project tasks according to changes happening in the scope of the project.

The following are some differences that make PERT and Gantt unique in their ways.

How to create a PERT chart?

To work on a PERT chart for a project, one must clearly understand the requirements for creating a PERT chart. PERT in project management helps in clarifying all necessary details about project tasks, project milestones, the progress of the project, and many other such concepts.

Here are a few steps that one can follow while designing a PERT chart.

Step 1: Break down Your Project Scope

Step 2: Creating a PERT chart

Step 3: Estimating Duration

Step 4: Find Critical Paths

Step 5: Manage Task Progress

- Break down Your Project Scope

First, identify the project milestone and the project tasks required to achieve it. This helps you identify the sequence of project activities, tasks, and dependencies.

The details then obtained can be listed out for categories, and you can use these elements to create a PERT chart. These elements or details will be more than sufficient to start creating a PETR chart.

A PERT chart can be created manually or by using Project Management software tools.

- Creating a PERT chart

With all the details listed, you can now make a PERT layout as shown in the reference. Multiple references are already available online. This helps you save time when creating a new chart layout from scratch.

The most important task while creating a PERT Diagram layout is to sequence the tasks so that the elements representing project tasks can follow the same sequence. This diagram helps in estimating the time required to complete each task.

- Estimating Duration

Now that the sequence of project tasks and activities has been determined, it is time to create a project schedule. Making use of the PERT chart formula, the time estimated for completing each project task can help in estimating the project duration.

One can create charts hassle-free by using project management software tools. PERT tools or software help you automatically design an interactive schedule chart. These charts also help you identify task dependencies, task milestones, project deadlines, and more.

- Find Critical Paths

Once the chart is completely done, including all the necessary details, you can now calculate all possible critical paths and identify the flows in the flow of the project. By eliminating these flaws, your required PERT chart is finally done.

- Manage Task Progress

The planning is done. But don't just leave it at that. You need to follow through and check the regularity of the progress. Keep on updating the pert chart when you think necessary. Updates should be made on these factors:

• Completed tasks
• Delays
• Changes in timeline

One advantage of following through is that it lays bare potential bottlenecks. It will teach you where to adjust schedules or resources. It keeps the project on track.

As the chart is now done, it is important to remember that this project schedule management chart is a document that requires your attention as the project progresses.

Hybrid, Agile & pert in project management

Currently, most organizations implement a hybrid model, integrating Agile for execution and predictive techniques for planning. PERT adds value by giving a realistic timeline forecast before sprints or releases begin.

• When it comes to estimating uncertain activities, PERT is the tool for you. Adds the term “realistic” to plans before sprints.
• Serves as a reliable planner when timelines vary.
• Acts as your personal assistant for predicting dependencies and risk windows.
• It offhandedly beats the pert cpm chart when it comes to making accounts for unknown variables.

It has the following disadvantages:

• One major drawback of the pert in project management is data dependency. pert planning can give you wrong estimates if the data is incorrect or outdated 
• The PERT model is difficult to implement due to its complexity
• Subjective activity time estimates.
• Maintaining pert is complex and costly.
• Differences exist between the actual distribution and the PERT beta distribution, resulting in wrong assumptions.

Conclusion

Program Evaluation Review Technique, or the PERT in project management, is a visual technique used for project planning. The PERT model is used to describe project planning in the form of a chart, which makes it simpler to schedule and arrange project tasks & timelines.

To share an update on the ongoing project, you can make use of various tools, and the progress can be telecast in real time. The submissions of the project can be precisely estimated since the work progress is being updated in real time. PERT planning coordinates the schedules of all tasks involved in a project. Furthermore, Pert in project management enables real-time monitoring of the overall project's development.

In case of any failure of the project, the manager takes full responsibility for deciding the hierarchy of the tasks involved in the project. Also, by not utilizing the right tools and proper procedures, the project can go wrong at any time.
