The most extended set of tasks that need to be done to finish a project is known as the critical path in project management. The critical route actions are referred to as critical activities because if they are delayed, the project as a whole would be delayed. Finding the critical route is crucial for project managers since it enables them to calculate the project's overall time precision. Recognize resource limitations, task dependencies, and project concerns. Establish job priorities and realistic project deadlines.
An algorithm that lets you schedule projects' tasks and activities is called the critical path method, or CPM. This approach is best suited for complicated projects with plenty of related jobs. It is a project management approach carried out step by step to identify tasks that would assist the project to be finished on time. This technique is also known as critical path analysis.

What is the Critical Path Method?
One of the tools for project management is the critical path method. It was accepted as a practice whereby it helps to sequence different activities or schedule the same as per the duration of a project. When a project has a deadline and a number of tasks are lined up, it helps to define the path and project timeline for the same. When a task is delayed it often leads to the entire project being delayed. Some projects can have multiple paths while some can have only a single critical path that needs to be identified.
Also known as critical path analysis, it is a technique of project management that is done step by step to identify activities that would help the project to be completed on time. This takes on a certain approach to scheduling by defining certain tasks for the project. These are then displayed in the form of flow charts and help calculate project duration as per the estimated duration for every task to be completed. Tasks are identified to be critical as per time and with respect to project completion.
2. History of Critical Path Method
If we look at critical path analysis and its history, this technique of project modeling was introduced in the late fifties. The method was worked upon by James E. Kelley Jr. and Morgan R. Walker. Both were working with reputed companies and together formed CPM or critical path method in the year 1989. There was a simultaneous development of a method called program evaluation and review technique which can be called a precursor to critical path project management.
Since its introduction critical path analysis has been used in different projects in sectors as diverse as aerospace, construction, defense, research projects, software development, product development, engineering and others. It is also called a mathematical analysis method that can apply to a project which includes interdependent activities. The term is used to analyze different logic diagrams of projects or networks.
3. Why is Critical Path Method Important?
There are several benefits that critical path project management provide for which it is a popular approach, especially when a project involves several tasks that are important. Those who are experienced in project management might feel that they are easily able to pinpoint tasks that are critical. However there are ways that critical path analysis can help to make a project successful.
Shorten Timelines
In critical path project management, bar charts usually are used which can help users visualize the activities of a critical path, task durations and sequences of the same. When it comes to software like Smartsheet or Edraw, the tasks of such path are in red outlines and easy to spot; they are made to stand out in the timeline of a project as well as showcases correlation between the different tasks. Users are able to know which tasks are important, durations that need modification and so forth.
Improve Resource Management
This is another benefit that critical path analysis provides. It gives enhanced visibility and clear direction as to what is coming up next and who needs to work on it. Once critical tasks are identified and assigned to different people, it helps a project manager to allocate resources in a better manner.
Plan Better
This is another reason why critical path method is often adopted in project management. It helps to compare progress as planned with what has been actually achieved. PM can identify tasks that are completed, plan or predict the time required for tasks coming up and changes planned for future tasks; this results in updates in schedules often and can help a project timeline to be monitored efficiently.

4. PERT vs. Critical Path Method
Two popular methods for project management are critical path method and PERT. There are distinct differences and similarities that both methods provide.
Similarities:
-
In terms of commonalities, both can be defined as project management techniques that help plan activities or monitoring of the same to reach project timelines or results in time.
Differences:
-
PERT is an approach which takes into account uncertain activities and how to handle the same in a project timeframe. On the other hand, CPM is taken on as a statistical technique where project management is based on managing activities that are well defined for a project.
-
PERT deals with planning and control techniques while CPM is about controlling time and costs.
-
PERT is event oriented while CPM is activity oriented. The former is mostly event driven while CPM is activity oriented. Accordingly, PERT is based on probabilistic modeling while CPM is a deterministic model.
-
Other differences include focusing on time in PERT, while in CPM it is mostly about time and cost trade off. While PERT is used mostly for research and development projects, CPM is mostly about non research project like ship building, civil construction and others.

6. Critical Path Method Examples & Templates
When used appropriately, critical path analysis can determine task dependencies, resource limitations, and project dangers. The time required to perform each task accurately. Prioritize jobs according to their float or spare time, determine the urgent jobs and track the status of your project, and gauge schedule variance. Try to utilize schedule compression strategies like crash duration and rapid tracking.

Example 1: Project Management Critical Path Method
A business relies on a business criticality matrix to carry out all of the daily tasks necessary to keep the firm running smoothly. Diagrams of the business criticality matrix help examine the relationships between two or more data categories. EdrawMax makes it rather easy to create a matrix diagram.
Example 2: Tottenham Critical Path Analysis Chart
To complete a project, each crucial task must be outlined using the critical path analysis (CPA) project management technique. It requires figuring out how long each step takes to complete and whether any actions depend on one another.
Example 3: Critical Path Precedence Diagram
The activity sequence that reflects the longest path across a project in the Precedence Diagram Method (PDM) is called the critical path. It establishes the quickest project duration feasible. The most important actions are those that have no float. The Precedence Diagram Method is the order of planned activities that establishes the project's length.
