1.2. ACTIVITIES TIMING AND TOTAL FLOAT To determine timing of activities in the network diagram the following calculations were done for each node: Earliest Start-(ES)‚ Earliest Finish-(EF)‚ Latest Start-(LS) and Latest Finish-(LF). Field and Keller (1998‚ p. 191) ES and EF are found by using the forward pass through the network … from the unique project start node and ends at the unique project completion node. ES is the ending day for the previous node/activity‚ where more than one

In the world of project management‚ utilizing the three-point technique can prove to be an invaluable tool. In addition to the three-point technique applying the earliest-start (ES)‚ earliest-finish (EF)‚ latest-start (LS)‚ and latest-finish (LF) procedure to identify the critical path‚ the project completion time‚ and the slack for each task can prove to be set of invaluable data that will assist the project manager in accurately determining task duration estimates for the entire scope of work

how to create a network diagram‚ and how to do a forward and backward pass to determine the ES‚ LS‚ EF‚ LF and slack (float). You will also learn how to determine the duration of the project‚ and the critical path. In this homework assignment‚ you will be working through four Activity In Box (AIB) problems. Using the activity‚ duration‚ and predecessor information given in this document‚ you should first construct a network for each "project." [Each problem will have its own network.] Once you

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start

medium-sized engineering firm has three separate engineering offices. In each office‚ a local LAN supports all the engineers in that office. Due to the requirement for collaboration among the offices‚ all the computers should be able to view and update the data from any of the three offices. In other words‚ the data storage server within each LAN should be accessible to all computers‚ no matter where they are located. Draw a network diagram that will support this configuration. 3.

What is project management‚ and what are its main objectives? What is the relationship between tasks and events‚ or milestones? What is a work breakdown structure? How do you create one? What are task patterns‚ and how can you recognize them? Compare the advantages and disadvantages of Gantt and PERT/CPM charts. Define the following terms: best-case estimate‚ probable-case estimate‚ and worst- case estimate‚ and describe how project managers use these concepts. How does a project manager calculate

According to the network diagram above The critical path of the project is: Activity 1 Activity 2 Activity 5 Activity 7 Activity 10 Activity 13 Activity 15 As audit of liquid assets (activity 4) is not on the critical path‚ it is not a critical activity. This slack job has a slack time of 178 hours for which slack time= late start time – early start time (231-53) = late finish time – early finish time (266-88).
