Project Scheduling

What is the first step in project scheduling?

• Estimate activity duration

• Determine the activities

• Draw the network diagram

• Perform critical path analysis

What is the formula used to estimate activity duration under normal conditions?

• Duration = Quantity of work × Production rate

• Duration = Quantity of work ÷ (Production rate × Number of crews)

• Duration = (Optimistic + 4 × Most Likely + Pessimistic) ÷ 6

• Duration = Total float × Free float

What is the main purpose of the Critical Path Method (CPM)?

• To determine the shortest project duration

• To track financial expenditures

• To allocate project resources

• To calculate the probability of project completion

What does a dummy activity in a network diagram represent?

• An extra task that must be completed

• A fictitious activity to maintain logical relationships

• An activity with the longest duration

• A critical path activity

In project scheduling, which method is used to account for uncertainty in activity duration?

• Critical Path Method (CPM)

• Precedence Diagram Method (PDM)

• Program Evaluation and Review Technique (PERT)

• Line of Balance (LOB)

What is the formula to calculate the expected activity duration (E) in PERT?

• E = (O+4M+P)​/6

• E = (P−O)/6

• E = (LS−ES)/D

• E = (LF−EF)/D

Which type of network diagram places activities on nodes rather than arrows?

• Activity on Arrow (AOA)

• Activity on Node (AON)

• Gantt Chart

• Line of Balance

What is the significance of the critical path in a project schedule?

• It shows all activities with the highest cost

• It is the longest path through the network with zero float

• It contains only activities that can be delayed

• It represents the shortest sequence of activities in the project

Which of the following best describes Free Float (FF)?

• The total time that an activity can be delayed without affecting the project completion date

• The total time utilized in the current activity that interferes with its following activities

• The amount of time that an activity can be delayed without affecting the early start of succeeding activities

• The total time that can be used to reallocate resources

Which project scheduling tool provides a visual representation of activities and their durations over time?

• Network Diagram

• Gantt Chart

• Precedence Diagram Method (PDM)

• Critical Path Method (CPM)
