Q: True or false if false correct in " SHORT " answer ?

1- Resource leveling is used on projects which are Time-constrained. ( )

2- Heuristics are used in resource-constrained projects to develop the near optimal schedule. ( )

3-Adding the schedule variance to the cost variance will not give the total project variance. ( )

4.Due to the impact over a long period of time, risk events that occur in the early stages of a project will have a greater cost impact than those that occur in later stages. ( )

5.During risk identification the smaller risks should be identified first because they will naturally lead to identifying the larger risks. ( )

6.One of the disadvantages of resource leveling is the increase in the flexibility of the network.( )
