Make a list of the tasks that is necessary for Management Trainee Officer job in private banks. Develop a table showing each task, its duration, and preceding event(s). Develop a Network diagram for these tasks. Highlight the critical path on your Network diagram and find out slack of all activities.
The Industrial and Systems Engineering Department at Sun University is moving from its old building to a new building. The move must be completed within the 14-day period between semesters. A list of tasks (activities) has been prepared. The activities and precedence requirements are presented in the table below. Three time estimates (in days) are given for each activity: optimistic time, most likely time, and pessimistic time. (a) Perform a forward pass and backward pass through the network to determine the critical path, and the expected duration of the project (b) What completion time should the department specify in its proposal in order to be 85% sure that it will complete the project on time?

The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table. Draw the project network, and compute the expected time and variance for each activity. Develop an activity schedule for this project, compute activity slack time and identify critical path.
