Unit 10

Question 1

Identify what does network analysis portray?

Answer 1

Network analysis is a planning method that allows a project to be completed in the shortest time possible.

Question 2

What factors does a network analysis include?

Answer 2

• Duration of each activity
• List of all activities
• Quickest completion time
• Float and no float to stress which activities must be completed in time.
• Duration that each activity will take to complete

Question 3

What information is required to construct a network analysis diagram?

Answer 3

Tasks/activites, duration of each task, the order in which they should be completed, earliest start time (EST) and latest finish time (LFT)

Question 4

What does the ‘circle’ symbol within a network analysis diagram present?

Answer 4

Node - activity number, EST, LFT (latest start time)

Question 5

Identify the importance of a critical path

Answer 5

Any delay in the competition time of an activity, identified through critical path, impacts the planned completion date of a project.

Question 6

Identify how the LFT and EST is calculated in a critical path network

Answer 6

EST: calculated from left to right, add durations, if a following EST has two nodes before it the larger EST will be chosen.
LFT: calculated from right to left, LFT minus the duration of the previous activity.

Question 7

Describe what is meant by the term ‘float’ and identify how it is calculated

Answer 7

Float represents the additional time an activity can over run without delaying the overall process.

Float = LFT - duration - EST

Question 8

Identify how ‘float’ is represented on a critical path

Answer 8

’//’ through the line of the activity with a float

Question 9

Identify potential advantages of constructing a critical path analysis
