Developing Schedule

Question 1

what 3 things does a developing schedule need to have

Answer 1

• a project network diagram
• activity duration estimates
• understanding of critical path method

Question 2

what does a developing schedule determine

Answer 2

• start and finish for all project activities, taking into account the activity
  sequences, activity durations, resource requirements and schedule constraints

Question 3

how to calculate earliest start (ES) and finish (EF) of an activity

Answer 3

ES = Maximum EF value from immediate predecessor(s)
EF = ES + Duration

Question 4

how to calculate latest start (LS) and finish (LF) of an activity

Answer 4

LF = Minimum (or lowest) LS value from immediate successor(s)
LS = LF - Duration

Question 5

what is the total float of an activity

Answer 5

• the amount of time an activity can be delayed without delaying the overall project duration

Question 6

how to calculate total float

Answer 6

= LS – ES or LF – EF

Question 7

what is the total float of critical activities

Answer 7

• 0

Question 8

what is a critical path

Answer 8

• the line of critical activities

Question 9

what is free float

Answer 9

• the amount of time an activity can be delayed without delaying the early start of any immediate successor activity

Question 10

how to determine free float of an activity

Answer 10

= ES of successor – EF of predecessor
