2. The table below provides a set of meanings or definitions in column 2, for the terms stated in column 1. Match up the meaning (col. 2) with it’s term (col. 1) and insert your answer from the first column, into the space provided in the third column.

Term

Meaning

Answer

(number)

1. Critical Chain

A. The reduction of the overall project duration by using lead time and buffers to overlap activities related through predecessor type relationships

2. Critical Path

B. The addition of time to delay the start of an activity

3. Critical Activity

C. The adjustment of resource allocation to ensure no resource is over allocated on any day

4. Fast Tracking Schedule Compression

D. Taking a progressive view of the plan, by revisiting it and adjusting it with greater detail when that detail makes itself known

5. Total Float

E. A network analysis method which produces a schedule with reduced activity durations and feeder buffers for critical paths and feeder chains, has a duration 75% of the original and has greater risk

6. Lag

F. The development of a project estimate on the basis of the historical information from past projects similar to the current project

7. Lead

G. The longest path through the project taking the shortest possible time

8. Resource Levelling

H. The period of time which a task has available for flexibility in its start or finish.

9. Rolling Wave Planning

I. Bringing the start date of an activity forward so that it starts earlier than originally intended.

10. Analogous Estimating

J. An activity on the critical path which has to start and finish on the days stated and for which a delay would impact on the project deadline
