For each activity, calculate the earliest start time (ES), earliest finish time (EF), latest start time (LS), latest finish time (LF), and total slack (TS). Assume that the required completion time (target) is like your answerin part (f). What is the estimated completion time to finish this project? g. Define the critical path in English using your own words. List all paths and their associate total time. Copy and paste the chart and diagram on your MS Word file.

You can draw parts (a) and (b)manually or using any software you like, such as Word, Excel, Visio, ProjectLibre (open source), and Microsoft Project. It is an app for task management, work breakdown structure generation, resource allocation and tracking, and Gantt charts that provide a view of the critical. ProjectLibre is an open source project led by Marc O’Brien and Laurent Chretienneau intended as an alternative to commercial software like Microsoft Project.

In the next page, let us see how to calculate Float for activities. To do so, I click on Add New Columns and choose field Text1: Next, we rename the field from Text1 to Business Critical: Now we have. If managed well, the whole project can be completed within the critical path’s duration. To mark individual tasks as critical per our own definition and not with regards to critical path relevance we need to use one of the custom fields in Microsoft Project. Note that sum of durations of all activities on critical path comes 49 minutes, and sum of duration of ALL activities on the project is much longer. In our example this is the second path: A -> B -> C -> D -> G -> H, which comes to 49 minutes.įigure 3: Assemble train set – Critical Path The network path with longest total duration is the critical path!Ĭritical path is the shortest duration required to complete the project successfully. This is how it looks, with individual activity duration in minutes –įigure 2: Assemble train set – schedule network diagram Step 3: Find all Possible Pathsįind all possible paths through the diagram, there are 3 in our case –Ī -> B -> C -> E -> G -> H Step 4: Calculate Duration for Each Path Sequence activities and build schedule network diagram (output from Sequence Activities process). Don’t forget to save your project regularly In the next tutorial we are going to see how we can add resources and create sub-tasks. That completes ProjectLibre Tutorial Part 1. Step 1: Find ActivitiesĪctivities for this project are as below (output from Define Activities process) – As you can see in this image below, this is a great way to visualize your project’s critical path. When Task E precedes Task F with FF link, it means that only once Task E ends will. Example: only once the lecturer begins speaking, students can begin taking notes. This project involves assembling a train set.Ĭalculating Critical Path is a simple 4-step process. When Activity C precedes Activity D with the SS link, it means that only once Activity C begins will Activity D be able to begin. Let us take a simpler example than John’s home construction example we saw in previous lessons.
In other words, critical path is the longest path in your project’s schedule network diagram, and is the SHORTEST possible duration for the project.

🙂Īs we saw in Developing Project Schedule project management activity, Critical path is made up of series of activities from beginning to the end, where each activity has a dependency over previous activity in such a way that delay in any one activity causes delay in all subsequent activities, causing the project to slip.Ĭlick here to get my PMP exam brain-dump for free. I suggest you get yourself a cup of your favorite beverage (I was going to say Coffee), this one is going to be a long ride. You will learn how to calculate critical path, float/slack, early & late starts, and early & late finishes of a network path in this article.įor easier understanding this post is divided into four parts that can be navigable at the bottom of each part. This is a part-post from Developing Project Schedule project management activity post.
