Find the slack time for each activity. 10 marks f. If task G was delayed by 1 days, how will this affect the project critical tasks and the project finish time? 5 marks g. If task H was delayed by 3 days, what will be the impact of that delay on the project finish time? 5 marks h. Use Project Plan 365 to produce the Gantt chart & network diagram of the project. 10 marks Q3) Figure 2 shows the EVM data of a project. The budget is $100,000 and the project duration is of 10 months. It started on 1st Jan 2008. It is now 31st July and the table shown the actual cost (AC) and earned values (EV). Activity "Incorporate feedback" is 75% completed as today.
