pert chart examples with critical path: Numerical on PERT Program Evaluation and Review Technique


It contains task nodes that are laid out in a network diagram. All the nodes include detailed data about the task, time estimations, durations, and start/finish points. A PERT diagram estimates the duration of individual tasks and the entire project, so it can be applied when you need to define the expected duration even at the project planning phase. A visual timeline helps project managers understand what is needed in each project stage. They can plan out how many employees they need, resources, software, and other requirements. It also helps project stakeholders understand their role in the process.


We start with the first node which is the “kick-off meeting” in our example. Then we represent the initial activities with arrows and connect them to their corresponding milestone nodes. We continue the process until we get to the final milestone node of our project. Now that you have drafted a PERT diagram and added task details, it’s time to add the estimated durations of all tasks to create a project schedule.

This assumes that all the necessary resources have been put in place and all the predecessor activities have been completed as was initially planned. This estimate is hard to achieve most of the time because projects are expected to face some challenges. It is often difficult to determine the time within which a project can be completed when it is being done for the first time. Therefore, in cases where there is no historical data, PERT comes in handy. It is the most suitable method for providing deadlines for every task involved in a project and guiding teams on the sequence of all the activities involved.

One can also gather ideas for flow chart template, sales strategy template, making charts, graphs by using the PERT chart. The given PERT Chart example helps to plan an event PERT Chart. Using this chart, an event manager can adjust his resources, funding, initiative, logistics, budgets, targets, reports, deadline, and goals. One can pretty well guess the intangible and accessible outcomes that may help in publicity. This cross-platform software solution runs on Windows, macOS, and Linux. It provides user-friendly templates for almost all types of diagrams and charts.

PERT Chart

The PERT chart is a tool that helps project managers plan and schedule. ProjectManager helps you take that PERT chart and apply it to managing your whole project with our online Gantt chart. It plans, schedules and works through the execution of the project.

This pert chart examples with critical path was applied in large-scale projects where time is the major factor and allows for scheduling projects without knowing the details and durations of all activities. For example, it was used in planning the 1968 Winter Olympics in Grenoble. It provided the organizators with the in-depth analysis of all the Games activities and processes before the kick-off date. Build your PERT chart using Mind Maps in ClickUp by creating nodes, adding color-coded connectors, and rearranging tasks into a logical sequence. A major benefit of ClickUp Mind Maps is that they are easily formed, edited, and shared. For instance, if you know how long it takes to complete each step of your project, you can use the critical path method to see which task takes the longest.

Generate tasks from PERT chart

Not only do these ease make them easier to draw, they also make modification of plans easier and provide facilities for monitoring progress against plans. In these, circles show events within the project, such as the start and finish of tasks. The number shown in the left hand half of the circle allows you to identify each one easily. One disadvantage of using a Gantt chart to track a project is that it does not indicate task dependencies. This makes it difficult for project managers to know how much one missed deadline could affect other chart tasks.

  • However, arriving at estimates is not as easy as it sounds.
  • The number at each node represents the duration of each activity.
  • Another benefit of using a PERT chart is it allows project managers to create what-if scenarios.
  • PERT charts can be created using a variety of tools, including project management software.
  • As technology pushes forward, project management changes with it.

To conduct a PERT analysis, use standard deviation to determine the amount of variation in your data. For maximum benefit, consider using CPM in conjunction with PERT charts. Implementing both in your project management strategy can provide your team with a realistic deadline and optimal process flow for the best results possible.

How to calculate the Critical Path with Examples 🥇

Together, the PERT and Critical Path methods had the biggest impact on the field of project management since the Gantt chart. Drilling and planting the posts have an optimistic duration of 7 hours, an expected duration of 10 hours, and a pessimistic duration of 12 hours. The optimistic duration is counted once, the most likely time is counted four times, and the pessimistic time is counted once. The entire sum is then divided by 6, and the weighted average is 9,83. You perform this calculation for each event and then share it by inserting it into the duration data column.

We will no longer have any free time so I must start working on the essay from the very beginning to get it done on time. Since this activity has no chance of being delayed, we call it a critical activity. However, there are several software solutions available that can simplify and automate the creation of PERT charts. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time.

This refers to the most extended path in the PERT chart, which connects the nodes that fulfill all four conditions. When coming up with a chart, one should ensure that all the related activities are captured in a series right from the first to the last. You will be good to go as long as you understand the formula involved in time estimation when using this technique. Let us break this down further and put it into perspective.

  • An effective Critical Path Analysis can make the difference between success and failure on complex projects.
  • If you’re trying to shorten the duration of a project, you can use a critical path diagram in conjunction with a PERT chart.
  • These connections consist of arrows, which represent tasks, and nodes, which represent events or milestones.
  • In this article I have combined these concepts for determining the project schdule.
  • While CPM focuses on time, PERT focuses on the time-cost trade-off.

Critical Path is more useful for projects where task length is easy to predict, such as a construction project or a large conference. Final deliverable, 1.1 tasks, 1.1.1 sub-tasks, as shown in the example diagram for building a house. PERT is centered around important dates, known as milestones. The most important milestone is the final due date, and managers work backwards from there.

Create powerful visuals to improve your ideas, projects, and processes. Use the formula below to find the PERT chart standard deviation. The larger your results, the less confidence you have in your estimate, and vice versa. To begin our PERT example, we’re going to identify all the activities that make up the project and determine the immediate predecessors for each. Project Practical is a management and career blog that was created by business professionals. Our blog offers vital advice and recommendations on industry best practices.

The Critical Path Method is a method of control of time and costs, however, PERT is a technique of planning and control of time. In the Critical Path Method activity durations are well defined but in PERT Method, time estimations are uncertain. An administrator can use PERT chart maker to create a perfect PERT Chart. Various platforms offer multiple templates that the team leaders can modify. They can also share the PERT Chart concepts amongst the team members.

In the mockup here, you can see an example of this after node 2, for example. The team may work first on the activities leading to node 3 or node 4, or they may choose to complete them simultaneously. In the PERT chart example below, you can see the task represented in node 1 has a dependency because its arrow goes only to node 2. From node 2, however, the team may work on either or both of the tasks represented by the diverging arrows going to nodes 3 and 4. PERT charts solve this challenge with the use of directional arrows. These directional (or “concurrent”) arrows indicate that a series of tasks must be completed in sequence because they have interdependencies.

Critical Path Analysis formally identifies tasks which must be completed on time for the whole project to be completed on time. It also identifies which tasks can be delayed if resource needs to be reallocated to catch up on missed or overrunning tasks. The pert chart template excel is used extensively and extremely popular in the project management industry. It indicates and highlights the project’s important decision-making process details.

The critical path method is a popular project management approach that focuses on just the essential tasks needed to finish a project. Determining your critical path is beneficial for projects that are falling dangerously behind schedule or feel too complicated to even start. Create a critical path calendar to manage projects efficiently. On this template, you’ll find columns for work breakdown structure, project stages and tasks, status for each activity, and timeline dates.
