Summary Introduction
Interpretation: Type of probability distribution with which individual task times can be modeled is to be determined.
Introduction:
PERT diagram is a graphical project management tool used to organize and analyze project and it’s activity. It defines time duration for a project and also for each activity in a project.

Suppose the optimistic estimate for completing a particular task is 2 weeks, the pessimistic estimate is 38 days, and the most likely estimate is 20 days. The PERT weight average estimate to complete that task will be:
14 days
20 days
38 days
22 days
The critical path technique is important in project scheduling, but what exactly does it do?
Calculate expected time, critical path, variance, standard deviation, slack time

- Identify the many types of real-time scheduling methods available to the project team.arrow_forwardINSTRUCTIONS: Draw the AON network for Exercise 14 (pg ASSIGNMENT 200 & 201). Complete the forward and backward passes, calculate total slack for each activity, identify the critical path, identify the total project length (or how long it will take to complete the project) based on days, calculate free slack for appropriate activities, and create the Gantt chart. When creating the Gantt chart, you must include slack into the schedule.arrow_forwardDetermine the critical path(s) and slack time for non-critical activities for the project as shown below (time unit is “days”).arrow_forward
