Read FirstChoose one of the following two assignments to complete this week. Do not do both assignments. Identify your assignment choice in the title of your submission.Option #1: Determination of Critical Path of the Project Use the following table to calculate duration (round to 0 decimal places) ID TASK NAME Optimistic Most likely Pessimistic Precedence Duration 1 First 1 2 4 2 Second 3 5 10 1 3 Third 9 11 13 2 4 Fourth 3 5 6 3,8,9 5 Fifth 6 7 8 4,11 6 Sixth 5 6 8 1 7 Seventh 3 5 8 6 8 Eighth 1 2 5 7 9 Ninth 1 3 5 6 10 Tenth 4 5 6 9,8 11 Eleventh 3 4 5 10 12 Twelfth 4 5 6 11 13 Done 0 0 0 5,12 Use Activity on Node to construct a network activity diagram with the preceding table. ES Task LS EF Dur LF Use the forward and backward pass method to calculate project duration, based on the assumption that the expected duration of each activity can be calculated using the following formula: Expected Duration = (Pessimistic Duration + 4 x Most Likely Duration + Optimistic Duration)/6. Include slack on the arrows and identify the critical path(s) and burst and merge activities.Evaluate the finished project and write a review of your analysis and how you completed each step. Include the completed table and your AON diagram in your paperYour response should be integrated in a well-written paper that meets the following requirements:Be 2-3 pages in length plus graphical elements, placing these graphical elements in an appendix,Be formatted according to the CSU-Global Guide to APA and Writing Requirements (Links to an external site.), andInclude two scholarly sources from the CSU-Global Library (Links to an external site.).Option #2: The PERT Method Using past course texts, current suggested readings, and other scholarly resources, write an overview of PERT analysis and calculate the critical path based on a recent project that you have participated in.The review of the PERT analysis should include the following:Define PERT and why it is used.Differentiate between activity on Node and Activity on Arrow.Define the forward and backward pass method for calculating critical path.Define burst, merge, and slack.The PERT analysis of your project should include your appendices with a WBS, and network diagram with forward and backward pass calculated according to the following specifications:An initial WBS of your project that has no less than 4-5 Major tasks,Each major task should have several subtasks,Calculate the critical path, andIdentify any tasks that have slack.(Include slack on the arrows and identify the critical path(s) and burst and merge activities.)Lastly, conclude with a summary of importance of PERT and Critical Path analysis in project management.Your paper should meet the following requirements:Be 3 pages (minimum) in length,Be formatted according to the CSU-Global Guide to APA and Writing Requirements (Links to an external site.), andInclude two scholarly sources from the CSU-Global Library (Links to an external site.). "Current" means published in the most recent 5 year period. "Scholarly" means peer-reviewed journal articles, and may also include the textbook and PMBOK Guide.
