Exam 2: Project Management

To calculate the probability of completing a project by a certain date:

The ________ is a statement of all work that has to be completed.

Table 2.10 -Using Table 2.10,what is the latest start time for activity E?

The earliest start time is never the same as the latest start time.

Table 2.3 -Using Table 2.3,which activity is on the critical path?

Table 2.11 -Using Table 2.11,what is the earliest completion time of this project without crashing?

Risk is a measure of the probability and consequences of not reaching a defined project goal.

Table 2.2 -Using Table 2.2,what is the earliest expected time of completion of the whole project?

Consider a project that consists of three consecutive activities of equal length as shown in the network diagram.The project manager would like to complete the project as quickly as possible and realizes that the diagram's logic is misleading.Instead of waiting until activity A is completed before activity B can begin,he can actually begin activity B once activity A has begun.The same reasoning holds for the relationship between activity B and activity C.The project manager decides to divide each activity in half,a technique known as "laddering".The second diagram shows the new network logic.In this diagram,activity A is divided into activity A1 and A2 where A1 must be finished before A2 can begin and before B1 can begin.The manager still isn't satisfied with the completion time of the project.Derive an expression or draw a diagram that demonstrates the fastest possible completion time of the project.

Project managers should be able to organize a set of disparate activities.

A Gantt chart is a project schedule that superimposes project activities on a time line.

What options do project managers have to alleviate resource problems? Briefly describe each method.

Table 2.14 You are responsible for managing a project with the following activities (times are given in weeks). -Using Table 2.14,which activity has the largest slack,and how large is that slack?

In making an estimate of the most pessimistic time for an activity,a manager deliberately estimates this time too high (i.e. ,longer than it should be).What is the result of this action,assuming the beta distribution is being used to make time estimates?

Table 2.6 -Using Table 2.6,what is the latest start time for activity E?

A pure project organizational structure houses the project in a specific functional area.

Table 2.12 -Using Table 2.12,what is the earliest completion time of this project if normal times are used for all activities?

Which one of these steps in implementing changes comes first?

Describe how time-cost tradeoffs for project activities should be identified and analyzed.

Table 2.13 (All activity times for the project are in weeks. ) -Using Table 2.13,if the expected time for activity E is changed to nine weeks,by how many weeks will the project's expected completion time increase?
