Schedule

Question 1

Project Schedule Network Diagram

Answer 1

a graphical depiction of the relationships among project activities

Question 2

4 Types of Dependencies

Answer 2

Mandatory (hard logic, Discretionary (soft logic), External, and Internal

Question 3

Logical Relationships

Answer 3

dependencies between 2 activities where one must be finished or started before another task can start or end

Question 4

Lead

Answer 4

starting an activity prior to completion of preceding activity

Question 5

Lag

Answer 5

delaying the start of an activity after the completion of a preceding activity

Question 6

Bottom-Up Estimating

Answer 6

Breaking a project or activity down into smaller components, then rolling up costs or durations

Question 7

Analogous Estimating

Answer 7

Use a previous project as a starting point/reference

Question 8

Parametric Estimating

Answer 8

Use a statistical relationship to calculate cost or duration

Question 9

Three-point Estimating

Answer 9

weighted average to increase estimation accuracy; optimistic, pessimistic, most likely
Examples: PERT& Triangular Distribution

Question 10

PERT Formula

Answer 10

(Optimistic + 4xMost Likely + Pessimistic)/6

Question 11

Triangular Distribution

Answer 11

(Optimistic + Most Likely + Pessimistic)/3

Question 12

Total Float vs Free Float

Answer 12

Total Float - the amount of time an activity can be delayed without delaying the project completion date

Free Float - the amount of time an activity can be delayed without delaying the earliest following (successor) activity

Question 13

Critical Path Method

Answer 13

calculating the shortest path for the project, float for each activity, and possible start and finish dates

Question 14

Crashing vs Fast-tracking

Answer 14

Crashing - add extra resources, higher costs

Fast-Tracking - doing activities in parallel, increases risk

Question 15

Resource Leveling vs Resource Smoothing

Answer 15

Resource Leveling - adjust the resource schedule when resources have been over allocated; let the schedule slip to level out resources; Histogram

Resource Smoothing - adjust activities to keep resources from exceeding limits; completion date not delayed
