The Critical Path Method (CPM) is an algorithm for scheduling a set of project activities. It is an important tool for effective project management. ConceptDraw PROJECT implements this method to provide the user with a wide set of project management tools. Critical Path Method Diagram. The critical path method, or analysis, was developed in conjunction with PERT. Both techniques are used to manage projects within a specific timeframe. The critical path method calculates the longest path that is possible with your planned activities, then figures out the time constraints that each activity is under.
MacProject was a project management and scheduling business application released along with the first Apple Macintosh systems in 1984. MacProject was one of the first major business tools for the Macintosh which enabled users to calculate the 'critical path' to completion and estimate costs in money and time. If a project deadline was missed or if available resources changed, MacProject recalculated everything automatically.

MacProject was written by Debra Willrett at Solosoft, and was published and distributed by Apple Computer to promote the original Macintosh personal computer. It was developed from an earlier application written by Debra Willrett for Apple's Lisa computer, LisaProject. This was the first graphical user interface (GUI) for project management. There were many other project management applications on the market at the time, but LisaProject was the first to simplify the process by allowing the user to interactively draw their project on the computer in the form of a PERT chart. Constraints could be entered for each task, and the relationships between tasks would show which ones had to be completed before a task could begin. Given the task constraints and relationships, a 'critical path', schedule and budget could be calculated dynamically using heuristic methods.
One of the early proponents of MacProject was James Halcomb, a well known expert in the use of the Critical Path Method. Having supervised hand-drawn network diagrams for countless complex projects, Halcomb immediately recognized the promise of the WYSIWYG graphical interface and computerized calculation of the critical path. Using a Lisa computer housed in a case designed to fit under an airplane seat, Mr. Halcomb traveled the United States demonstrating this new technology in his CPM courses. In consultation with the software's developers he authored the book Planning Big with MacProject, which introduced a generation of Mac users to PERT and CPM.
In December 1987, an updated version of MacProject, called MacProject II, was introduced as a part of Claris's move to update its suite of Mac office applications.
In 1991, Microsoft Project was ported to the Macintosh from Microsoft Windows and became MacProject's main competitor. However, after the release of version 3.0 of Microsoft Project in 1993, Microsoft terminated support of the Macintosh release.
MacProject 1.0 is not Y2K-compliant as it cannot schedule tasks past 1999.

Critical Path Method
If your team is like most, it has several projects competing for attention with multiple contingencies and fixes looming on the horizon. The critical path method, or CPM, prioritizes the most crucial tasks first to keep projects in line and on time.
In 1984’s The Goal, a staple in the world of business management, Eli Goldratt tells a story about a scout troop out on a hike.
The group quickly learned that, no matter how fast some of the scouts could hike, the troop couldn’t reach their destination any faster than the slowest scout, Herbie, could go. So they put Herbie in front and helped him hike the best he could.
One big takeaway from this story? You have to determine the dependencies of a project (your Herbie) before you can figure out exactly how long the project will take.
With the critical path method, you can better manage projects and anticipate timelines by finding which tasks depend on the completion of other tasks and outlining the fastest way to the end of your project.

If your team is like most, it has several projects competing for attention with multiple contingencies and fixes looming on the horizon. Often used along with PERT charts, the critical path method, or CPM, prioritizes the most crucial tasks first to keep projects in line and on time.
Since the 1950s, critical path project management has provided the ability to outline a project’s longest sequence of tasks, referred to as the critical path, so project managers can determine the minimum amount of time a project will take. So how do you go about finding it?
6 steps to finding the critical path
You can find the critical path of any project by completing the following six steps. https://gatewaysoha.weebly.com/add-new-email-mac-mail-app.html.
Step 1: Establish each activity
Create a diagram to identify all the deliverables within a project. A reliable way to do this is with a work breakdown structure. A work breakdown structure helps you pinpoint all the tasks in a project, making it both more manageable and measurable.
If the template above isn’t enough to get you started, see our complete instructions for how to create a work breakdown structure.
Step 2: Define the activity sequence
Project deliverables can be like dominos—ones farther along the path depend upon their counterparts falling first. List the proper order of tasks, considering with each activity the task that has to take place before it. A crucial step in the critical path method, streamlining the sequence of tasks is paramount in avoiding possible delays.

Step 3: Create the activity network diagram
The next step along your journey to the critical path is creating the activity network diagram, or critical path analysis chart (also known as the CPA). The purpose of the network diagram is to illustrate not only all of the project’s deliverables, but also the dependencies that you determined in the previous step.
Step 4: Determine the activity completion time

The last step before identifying the critical path is estimating the completion time for each task. You can calculate these times based on past experience or an estimation from your team members—some project managers use a three-point estimation to feel more confident. This is the last missing piece and the crux of CPM.

Step 5: Identify the critical path

Correctly identifying the critical path is completely contingent upon the previous step. Without accurate completion times, there’s no way to get a full picture of a project’s actual scope. Looking at your project network diagram, you can easily scan for the critical path, or the amount of time needed for your project based on the longest sequence of deliverables.
This step will also show whether your project has competing critical paths. If it does, the critical path might change once the project has begun, which increases the chance of a change in schedule.
Step 6: Update the critical path progress
Free software to make logos machines. With the blueprints of your project in place, all that’s left to do now is to continue updating your network diagram as you complete tasks with their actual completion times. By keeping your diagram up to date, you can evaluate if your project is on time and whether you need to make any adjustments.

Visualizing the ins and outs of a project using the critical path method will give you and your team a better understanding of how long tasks will actually take to complete and how every piece—and teammate—is dependent on each other to succeed.
With Lucidchart, you can create your own work breakdown structures and project network diagrams, and as you do, you’ll find the path that will make all the difference.
