Chapter 10 (Final) - Project Scheduling: Lagging, Crashing, and Activity Networks

* Prior to creating a network, it is important to: a. understand the activity precedence b. identify all loops through activities c. calculate the float for each activity d. identify the party responsible for each activity

A

* 1) The most common type of logical sequencing between tasks is referred to as the: A) Finish to start relationship. B) Finish to finish relationship. C) Start to start relationship. D) Start to finish relationship.

A)

* 24) One reason for crashing a project is: A) The project has slipped behind schedule. B) That the initial schedule may be too pessimistic. C) Market needs change and the project is not in demand any more. D) There are no repercussions for delivering the project late.

A)

* Serial activities are those that: a. have the same numbers b. flow from one to the next in sequence c. have sequential numbers d. should be performed simultaneously

B

* 2) A finish to start lag delay is usually shown: A) As an added value in the predecessor's activity time. B) On the line adjoining the two activity nodes. C) As an added value in the predecessors early start time. D) As a subtracted value in the follower's early finish time.

B)

* 25) Which of these approaches will NOT accelerate the completion of a project? A) Improve the productivity of existing project resources. B) Increase the bureaucratic oversight. C) Improve the working method. D) Increase the quantity of personnel and equipment.

B)

* Concurrent activities are: a. activities that use resources from the same resource pool b. activities that must be done one after the other c. activities that can be performed at the same time d. activities that use labor from the same group of workers

C

* 26) If an activity's cost is plotted against its duration on axes with zeros at the origin: A) The slope of the line is positive because it costs more to finish an activity more quickly. B) The slope of the line is negative because a shorter activity costs less than a longer one. C) The slope of the line is negative because it costs more to finish an activity more quickly. D) The slope of the line is positive because a longer activity costs more than a shorter one.

C)

* 23) The process of accelerating a project is referred to as: A) Streamlining. B) Expediting. C) Rushing. D) Crashing.

D)

* The amount of time an activity may be delayed from its early start without delaying the finish of the project is the: A. late start B. delay C. late finish D. float

D. float

* Finish to start lags are the same as additional activity slack.

False

* Gantt charts cannot depict float.

False

* Networks are adaptable and useful for all scheduling challenges that an organization faces.

False

* The critical path may not contain a dummy activity.

False

* AOA is a more useful technique than AON if the project is complex and has many significant milestones.

True

* Dummy activities are used in AOA networks to indicate the existence of precedent relationships between activities and their event nodes.

True

* In order to accelerate completion of a project, the manager must crash critical path activities.

True

* Most activity estimations using PERT methods lead to overly optimistic activity duration estimates.

True

* Quite often the marginal gains in employee productivity decrease dramatically with the increased use of overtime.

True

* The least common type of lag relationship occurs when a successor's finish is dependent upon a predecessor's start.
