Critical Path Analysis or Critical Path Method is a project modeling technique that project managers use to deliver projects on time hence meeting important deadlines. The critical path refers to the longest distance between the start and the finish, including all the tasks and their duration. You will have a clear picture of the project’s actual schedule once the critical path is determined. This can be achieved by the use of the algorithm to find the least amount of time needed to complete each task with the least slack.
Importance of Critical Path Analysis
The critical path method is one of the commonly used techniques in project planning. A typical project has many tasks that involve lots of different people, and this gives project managers a hard time keeping track of things. Sometimes forgotten tasks and errors in planning can affect the timescale of the whole project. For efficient and effective results, all activities added to the network diagram should be completed on time. This enables the manager to see how long each section will take. Applying each of the set time, critical and essential tasks to a network diagram is important because:
- It offers a reliable timescale to the client and helps to predict the time taken by each activity.
- Identifying the importance of each section and following closely on the progress of the rest of the project as a whole
- It helps assign corresponding tasks to the right team and department.
It is important to note that the estimated time refers to the time taken for each task at the beginning of the project. When working on the project, the estimated time might vary based on different factors, and in such cases, you should revisit your diagram and make some adjustments where possible. This is not something that frequently happens since most developers are accurate with their estimations.
Benefits of Critical Path Analysis
It demonstrates the graphical view of any project: It helps managers to get a useful overview of a project and be able to identify if it is a complex one or a simpler one.
It helps to identify the most important tasks to be managed: Efficient scheduling and estimation enable a manager to identify the complexion of the tasks and their degree of importance. It helps in comparison of planned and actual progress: This is achieved by estimation of the duration of a project, analysis of the step by step critical path network diagram that clearly shows how far the project is as compared to the anticipated result.
Making dependencies visible and clear: It provides a demonstration of dependencies, which helps in the scheduling of individual activities.
Identification of all the critical activities that need special attention
The critical path analysis breaks down substantial undertakings into smaller segments. The most complex projects are divided in a coordinated manner to create a set of individual and discrete tasks.
With these segmented parts of the project, it is easier to identify problematic issues or those that need special attention and the ability to effectively address them within the shortest time possible.
The focus on elemental parts of the project renders it easier to identify the potential for problematic issues or those that need special attention and the ability to address them within the shortest time possible effectively. The critical path method ensures the timely and proper allocation of human resources.
Key Steps in Critical Planning Method
The critical path method is a step-by-step project management system that identifies the most fundamental tasks along the project’s critical path. This technique utilizes a flow chart, which presents a dynamical visualization of the project as a whole, including the component tasks on the critical path. To further understand the critical path analysis, you need to have a general understanding of the key steps.
Make your activities specific
Accurate specification and identification of each activity is the first step in the critical path method. The activity listing should include only those higher-level activities. This will help in dividing the tasks into manageable sections. Too much specification should not be done as this will make the project becomes too complicated and very difficult to manage.
Improper identification of activities can result in the Critical Path Method not fulfilling its intended purpose of keeping a project valid and on track. When specifying each project activity, you first have to identify the primary deliverables. From this identification and the placement of the higher-level activities, it makes it easier to identify smaller work tasks.
The second step is to identify the interconnected project dependencies. Some activities are dependent upon the completion of others; therefore, some activities may start when others are complete. It is very important to graphically present the dependent activities in the proper and correct order. For proper utilization of the critical path technique, it is important to analyze some of three important questions:
- Which tasks should happen before a specific task?
- Which tasks need to be completed at the same time as this specific task?
- Which task happens after a specific task?
- Visualize a critical path
After identifying primary tasks and dependencies, it is necessary to come up with a critical part analysis chart or a network diagram. The network diagram is a visual presentation of all activities scheduled appropriately, planned based on the interconnected dependencies. This diagram can either been drawn by hand or use some software programs.
Project managers adopted the use of critical path network diagrams to get a view of projects that are broken into separate tasks. When coming up with a critical part diagram, it is necessary to use boxes, arrows, and circles since they help visualize the activities and dependencies. The next step is to clearly name each activity and highlight the paths.
Estimate the time of Activity completion
With or without enough experience, it is necessary to estimate the required time to complete all the tasks. The duration of a smaller project is measured in days, while a larger and more complex is measured in weeks.Time estimation in the Critical Path Method is comprised of three-point systematic estimates: the best case, the most likely, and lastly, the worst-case scenario estimate.These estimates are created based on experience from other completed projects, the advice of skilled personnel, and giving it a guess.

Most project managers have widely adopted the critical path analysis technique. The manner in which a project is handled is more important than its ultimate success. A critical path method is a multifarious approach in project management, especially when it comes to complicated endeavors. The most important aspect when applying this methodology is the definition of critical tasks versus non-critical projects. Efficiency is the main objective when working on a project, with significant activities being met without delays and interruptions. Critical path analysis is an important and effective method of accessing your task’s priorities, all parallel activities, the sequence of scheduling and timing, the shortest time possible to complete a project, and the resources needed to achieve the goal.
