Everything You Need to Know About Gantt Charts & the Critical Path MethodSmartsheet Contributor Diana Ramos Show
December 11, 2020 In this article, you’ll find everything there is to know about Gantt charts in relation to critical paths, including why you should implement the critical path method and how to use critical paths with Gantt charts. Included on this page, you’ll find the following: details on how to determine a critical path; examples of critical paths in Gantt charts; a table comparing a Gantt chart analysis to a critical path analysis; and many more helpful pieces of information.

Gantt Charts and Critical Path AnalysisBoth Gantt charts and the critical path method serve as indispensable tools for project management. They both help you track a project’s progress and manage the associated tasks to stay on time and on budget. With Gantt charts, you can track project tasks against a predetermined timeline. For further details on how to create a Gantt chart for your project, get free Gantt charts in Excel. If you’re looking for a variety of Gantt chart templates that you can use for projects of all sizes and types, click here. Critical paths, on the other hand, identify the sequence of project tasks that determine a project’s duration and outline important deadlines you have to meet to deliver a project on time. In short, the critical path is the longest distance, or duration of time, between the start of a project and its completion. When you use a Gantt chart in combination with the critical path method, you can track the path’s tasks over a specific time period, thus helping you keep your project on schedule and mitigate any problems. While your critical path analysis helps you make better scheduling estimates and decisions, your Gantt chart tracks this schedule and closely monitors your project’s timing and progress. When you have flexibility in monitoring the critical path on a timeline — such as by using a visual Gantt chart — you can more easily adjust your project schedule as it progresses and get an accurate picture of how each task is tracking. What Is a Critical Path in a Gantt Chart?A critical path in a Gantt chart refers to the phenomenon in which any individual task causes a delay in the related sequence of tasks, thus pushing back a project’s overall end date. You can easily determine if a particular task is on the critical path of your project by calculating whether the task delays the overall duration of the project. Similarly, you can easily determine whether or not a task is non-critical: If the task doesn’t affect the duration of your project, that task is non-critical. If money or time precludes you from completing non-critical paths, you can remove them from your project entirely. You use the critical path method to find the shortest path — or the least amount of time — necessary to complete each task. Such tasks also require the least amount of slack, and you must complete them within the designated time frame. Once you’ve determined your critical path by hand, you can then calculate it by using project management software. Difference Between a Gantt Chart and a Critical Path AnalysisThe main difference between a Gantt chart and a critical path analysis is that a Gantt chart offers a timeline view of a project, whereas a critical path maps the sequence of scheduled tasks that determine a project’s duration. A few other key differences separate Gantt charts and critical paths:
Critical Path Analysis vs. Gantt Chart AnalysisBelow, you’ll find a helpful comparison chart showing the differences between Gantt charts and critical paths.
How to Determine the Critical Path in a Gantt ChartTo determine the critical path in a Gantt chart, list all project tasks, calculate the duration of each task, identify all dependent tasks and critical tasks, and figure out any lag time between tasks. For more detailed steps with helpful images, refer to the information below. Steps to Identify the Critical Path in a Gantt ChartHere are the six steps to identify the critical path in a Gantt chart:
For downloadable, easy-to-use critical path templates, check out this collection of critical path templates and find the one that’s most useful for your next project. Gantt Chart Critical Path ExampleUse this template to list, track, and manage all project tasks, especially project tasks that are part of your project’s critical path. This template enables you to better visualize your project as a whole and track the progress of your project as you check off each task. Shorten or eliminate any unnecessary project tasks in order to maintain your estimated completion time and ensure that you carry out all critical paths. Download Gantt Chart Critical Path Template Excel | Smartsheet Why Should You Use Critical Path?You should use the critical path method to identify your earliest project completion date. This helps project managers better track and manage projects, as well as ensure that projects progress in a timely fashion. The Importance of Critical PathCritical paths are crucial because they help you keep your projects on track and determine what tasks you cannot miss or delay. Critical paths are also essential for the following reasons:

Which of the following is a scheduling tool that breaks down large projects into steps to be performed and specifies the time required to perform each step?Which of the following is a scheduling tool that breaks down large projects into steps to be performed and specifies the time required to perform each one? Explanation: C) A project manager uses a Gantt chart to keep the project moving on schedule.
What is the first process involved in project schedule management?Steps to Developing a Project Schedule. Step 1: Create a work breakdown structure.. Step 2: Estimate durations.. Step 3: Determine resources.. Step 4: Identify predecessors.. Step 5: Determine milestones.. Step 6: Identify dependencies.. Which of the following refers to a set of methods and technology is used to produce a good or service?test2bus101. What is true about the critical path?The critical path (or paths) is the longest path (in time) from Start to Finish; it indicates the minimum time necessary to complete the entire project.
