- DO IT MANUALLY, NO EXCEL (PERT-CPM) A small project consisting of eight activities has the following characteristics Draw the PERT network for the project. Prepare the activity schedule for the project showing (Project duration, ES, EF, LS, LF, FLOAT/SLACK). Determine the critical path.arrow_forwardA plumber has decided to use the techniques of project management in order to plan a job. He knew all the different activities of the job, their precedence and their average durations. They are shown on the table below. Activity Duration (days) Preceding activities A 3 None B 3 None C 4 A D 8 A E 2 B and C Required: 1. Draw a network diagram representing the sequence of activities and the dependence between them. 2. Determine how long it will take to complete the job by conducting the forward pass 3. By conducting the backward pass, identify the critical path and the non-critical path(s). Note: The work for this task should be produced using Word drawing facilities. The forward and backward passes should be clearly shown on the diagram. The calculations should be shown next to the network diagram.arrow_forwardb) Draw the project’s Gantt chart c) Change the time of at least two activities that can reduce the overall project duration, draw the new critical path and the new Gantt chartarrow_forward
- Please, I need help because I have no idea how to do any of these. 11. Building a backyard swimming pool consists of nine major activities. The activities and their immediate predecessors are shown. Develop the project network. For question number 12, you need to refer to question number 11. Also the first picture is for #11 and second picture(image) is for #12 12. Assume that the activity time estimates (in days) for the swimming pool construction project in Problem 11 are as follows: a. What are the critical activities? b. What is the expected time to complete the project? c. Based only on the critical path, what is the estimated probability that the project can be completed in 25 or fewer days?arrow_forwardYour hospital has applied for certification as a level 1 stroke center.
