Technical Writing for Success3rd EditionDarlene Smith-Worthington, Sue Jefferson 468 solutions This is a part-post from Developing Project Schedule project management activity post. You will learn how to calculate critical path, float/slack, early & late starts, and early & late finishes of a network path in this article. For easier understanding this post is divided into four parts that can be navigable at the bottom of each part. 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. 🙂 As 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.
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. How to Calculate Critical PathLet us take a simpler example than John’s home construction example we saw in previous lessons.This project involves assembling a train set. Calculating Critical Path is a simple 4-step process. Step 1: Find ActivitiesActivities for this project are as below (output from Define Activities process) –
Step 2: Build Schedule Network DiagramSequence activities and build schedule network diagram (output from Sequence Activities process) . This is how it looks, with individual activity duration in minutes – Figure 2: Assemble train set – schedule network diagramStep 3: Find all Possible PathsFind all possible paths through the diagram, there are 3 in our case – A -> B -> F -> G -> H A -> B -> C -> D -> G -> H A -> B -> C -> E -> G -> H Step 4: Calculate Duration for Each PathLet us see the duration for each of these paths – A -> B -> F -> G -> H —> 10+20+4+2+2 = 38 minutes A -> B -> C -> D -> G -> H —> 10+20+5+10+2+2 = 49 minutes A -> B -> C -> E -> G -> H —> 10+20+5+2+2+2= 41 minutes
Critical path is the shortest duration required to complete the project successfully. In our example this is the second path: A -> B -> C -> D -> G -> H, which comes to 49 minutes. Figure 3: Assemble train set – Critical Path
In the next page, let us see how to calculate Float for activities.. (please use the page numbered link below to navigate).. Pages: 1 2 3 4 What shape is used to represent an activity in an Aon graph?AoN Diagram
In this type of diagram, the activities are represented by nodes. The nodes are then connected to one another by arrows. These arrows are used to show the relationship between the activities.
Which of the following determines the critical path?A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
What determines a particular activity earliest start time?The earliest start time for a specific activity must be the same as or later than the latest of all the earliest finish times of all the activities leading directly into that specific activity.
Which of the following is determined during the forward pass?Which of the following is determined during the forward pass? longest time path through the network. PERT analysis computes the variance of the total project completion time as: The sum of the variances of all activities on the critical path.
