project Management -The following table is a very rough plan consisting of a list of activities

3. (20%) The following table is a very rough plan consisting of a list of activities, immediate predecessors, duration estimates, and resources required (one network engineer (NE) or one user interface architect (UI)) for a project to develop a network administration dashboard. There is only one network engineer and only one user interface architect available for the duration of the project.Given the resource availability noted above, calculate the earliest start time (ES), earliest finish (EF), latest start (LS), latest finish (LF), and slack for each activityIdentify the critical path for the projectWhat is the project duration?Activity Predecessors Duration ES EF LS LF Slack Resource RequiredA None 2 NEB None 4 NEC None 3 UID A 1 NEE D 6 UIF B 2 UIG C 4 NE4. (15%) Continuing with problem #3, calculate the project’s cost baseline using the following information:The direct labor costs are $500 per day for the network engineer and $400 per day for the user interface architectIn addition, a project manager will spend an average of 2 hours per day managing this project. The direct labor costs are $50 per hour for the project managerAssume $4,000 of other direct costs, e.g., project expenses such as the end of project partyAssume the project is assessed 20% of its total direct costs for indirect costs that are shared across all projects, e.g., janitorial services, utilities, etc.Finally, to address identified risks that may or may not occur (“known-unknowns”) include a contingency reserve of 15% of all other estimated costs
