Is it possible to shorten critical path and save money

The slack for the project is computed through the forward pass and backward pass technique. When Late finish equals early finish there is no slack in the activity. Therefore they must be part of the critical path because any delay in those activities would delay the project by the same amount of time. Larson, E. Project management, the managerial process. The schedule is something you will want to keep close watch on during the project.

You can also think of it as:the longest path from start to finishor the path without any slack,the path corresponding to the shortest time in which the project can be completed. The Critical Path is the longest path sequence of activities in a project schedule network diagram. Critical Path is one of the key outputs of the Project Schedule Creation activity. In Project Management the Critical Path is the series of tasks that must finish on time for the entire project to finish on schedule.

You can find information about the critical path method online at the Wikipedia. Once on the page, type "Critical path method" into the search field at the top of the page and press enter to bring up the information.

These critical path enables PMs to know which activities tasks are essential for Project Completion can delay the project , and which activities are not. It also gives a clear idea on how to accelerate the projects eg by adding more resources to the tasks on the critical path. Answer:Critical Path Method: This is the schedule network analysis technique used to identify the schedule flexibility and the critical path of the project schedule network diagram.

Because it is the longest path, it determines the duration of the project and hence the finish date of the project given the start dateThe Critical Path and Duration of the Critical Path, gives the project manager a clear picture of how long all the activities can take to complete.

It also helps him to identify the flexibility in the project schedule by calculating the early and late start and finish dates of each activity on each path. The schedule flexibility of an activity is measured by the positive difference between the late start date and the early start date for the activity and is called float time or total float. The purpose of critical path analysis is to become an important tool which will give your project an effective management by scheduling a set of project activities.

By reducing the time to completion for a task not on the critical path you can still reduce the duration of the project. Crashing a non critical task will also free up resources. Early Start Time is calculated by doing a forward pass through the Critical Path.

Usually the Early start for the first activity is 0 and increases as we traverse through the path Late Start Time is calculated by doing a backward pass through the Critical Path. Critical path method.

Critical Path Method CPM focuses on the time to complete the project and the other important activities on which a manager shall focus attention. Log in. Project Management. Study now.

As you modify tasks to resolve overallocations, adjust costs, or revise scope, be aware of the critical tasks and that changes to them will affect your project finish date. Critical tasks make up the schedule's critical path. A task stops being critical when it's completed, because it can no longer affect the completion of successor tasks or the project finish date. Projectdefines critical tasks as those that have no slack float.

However, you can change when a task becomes critical. For example, you can make a task critical if it has one or two days of slack. This is helpful if you want to be alerted to tasks becoming critical when you still have a day or two of buffer. Slack is determined by the early finish and late finish dates of the tasks in your schedule.

An early finish date is the earliest date that the task could finish, based on its start date and scheduled duration. A late finish date is the latest date that the task can finish without delaying the project finish. The difference between early finish and late finish dates determines the amount of slack.

For critical path tasks tasks that have no slack , the early finish and late finish dates are identical. If you want your project to have an earlier finish date, you must bring in the dates of your critical path tasks. This is also known as crashing a project. To do this, you can:. Break a critical task into smaller tasks that can be worked on at the same time by different resources.

Note: If you bring in the dates of your critical path, a different series of tasks could become the new critical path. There is always one overall critical path for any project schedule. The new critical path would then become the series of tasks you track more closely to make sure the finish date you want.

Tip: If you bring in the finish dates of the critical path and another series of tasks does not overtake it, then you can successfully bring in the finish date of the project.
