Exam 9: Project Scheduling: Networks, Duration Estimation, and Critical Path

Which technique would accelerate the completion of a project?

The best candidate activities for shortening the overall project are:

What is the early start time for Activity D given the activity times and precedence requirements shown in the table?

Use the information in the table to determine the early start time for Activity B.

Project Test Bank is composed of activities we will refer to as A, B, C, and D for convenience (and lack of creativity). Durations and precedence requirements are shown in the table. Each of these activities can be conveniently laddered into two sub-activities of equal duration. The first half of each activity serves as the predecessor to its second half and the first half of the original following activity. What is the expected completion time of the laddered project?

The least amount of float is found:

Activities C, D, and E in the project represented by the network are to be hammocked. What is the activity length of the hammock activity?

Based on the activity network pictured, what is the best statement?

Use the information in the table to determine the slack time for Activity B.

Discuss any five approaches to reducing the critical path. Which is the most effective and which is the most difficult to achieve? Why?

__________ is the identification of the project objectives and the ordered activity necessary to complete the project.

What is the earliest that Activity D can begin if Activity A takes 3 days, Activity B takes 5 days, and Activity C takes 7 days?

Use the network diagram and activity lengths in the nodes to determine the early finish time for activity G.

A merge activity has two or more immediate predecessors.

The length of time expected to complete an activity assuming that its development proceeds normally is called the:

Consider a project composed activities X and Y having equal length and performed in that order. Both activities can be laddered such that the first half of each activity is the predecessor for its own second half, so X1 precedes X2 and Y1 precedes Y2. The first half of X1 is also the predecessor for Y1. If the laddering procedure were performed again activities X and Y would be divided in four parts each, with precedence working as it did in the first split. Derive an expression for the minimum length of the project as laddering increases.

A project has the precedence requirements and activity durations shown in the table. After he draws the network, the project manager decides to represent a few activities by as hammock activity. Which is a legitimate hammock activity for this project?

Use the values in the table to calculate activity durations and variances for the project. Which path is critical? How closely should the other path be watched and why?
