Subtract the lag time or add the lead time to the late finish date.Subtract the predecessor activity’s duration from its late finish date.Follow these steps to calculate the late start dates of predecessor activities, assuming finish-start relationships: To calculate late start dates, begin with the project completion milestone and assign that date as the finish date of its predecessor activities. Resource calendars must be considered in the backward pass as well as the forward pass. Subtract the duration of each activity in each path to determine the latest date the activity could begin and still meet the project completion date. The next step is to work through the network diagram from right to left beginning with the mandated completion date, which is a milestone that is set in the project plan. Assign the calculated date as the early start date of the successor activity.Refer to the resource calendar (or calendars) that applies to the people and equipment necessary for the activity, and add the number of off-days that the activity would span on those calendars. Add the lag time or subtract the lead time.Add the predecessor activity’s duration to its start date.Follow these steps to calculate the early start dates of subsequent activities, assuming finish-start relationships: To calculate early start dates, begin with the project start date and assign that date as the start date of activities that have no predecessor activities. The estimate considers durations and resource availability calendars. The early start date for an activity is the earliest date the activity can begin. The dates derived by this method are the early start (ES) dates. Starting dates can be assigned to each activity by doing a forward pass proceeding from left to right in the network diagram beginning with the project start date. Derive the earliest expected completion time (T E), latest expected completion time (T L), and slack for each of the tasks (begin at time = 0).\) A Gantt Chart and a network diagram that includes the modification indicated on step “d.”Ĭapture the images of the requested charts and diagrams and paste in the Word document you will use to turn-in your assignmentĪssume you have a project with ten activities labeled A through J.A Gantt Chart for the project described in the table for problem 2.Using MS Project or Project Libre software, you will complete d) What would happen if activity 6 were revised to take six weeks instead of two weeks?. c) Show the critical path in your network diagram.b) Calculate the earliest expected completion time.MS Project or Project Libre file showing your work for problem 4Ĭalculate the expected time for the following activities.Word document-file integrating all your answers.Something similar applies to durations of more than one week. That means that in the “duration” field of a task you can enter either “5 days” or “1 week” if you want to schedule the duration of one week. Assume that a week has 5 working days.Also, I have provided video resources that illustrate how to use MS Project and Project Libre. Additional information is available in the body of the problem statement. This problem also requires capturing the images that show your work. Problem 3 requires using MS Project or Project Libre.Further,I posted videos or supplemental materials that show how to use MS Visio, Draw.IO, and the snipping tool (cropping) from Microsoft to facilitate your work. It is important that you upload a good quality image to facilitate the grading. After completing the diagram, you can capture the network diagram image, crop it and paste it in the Word document you will use to turn in your assignment. Also, you could use IO(Links to an external site.), or the shapes/drawing capabilities of PowerPoint or even draw the diagram by hand. You may use MS Visio, which is available on the Skylab assigned to the school of businessLinks to an external site.
