Project Management – Ch. 6

what is a project network? a. the reporting structure within a project team b. a group of team members connected through digital communications c. a graphical representation of the project flow in chart form d. a representation of activities with horizontal bars showing time to completion and relationship to the project

what is a horizontal bar chart showing activities /tasks with duration and timing?

Concurrent engineering, which has dramatically reduced the development time for new products, relies on what kind of lag? Finish to Finish lags Any of these could be correct Start to Finish lags Start to Start lags Finish to Start lags

The assumption that all immediate preceding activities must be 100% complete is too restrictive in some situations. When an activity is broken down into smaller segments in order to start the succeeding activity sooner, this is called Hammock activities. A forward pass. Concurrent engineering. Laddering. Dissecting.

Arrows on an activity-on-node (AON) project network represent Dependency. An activity and dependency. An activity. Project flow and dependency. Project flow.

Which of the following correctly calculates the early finish for an activity? LF + DUR ES + SL LF + SL LS + DUR ES + DUR

Activities which can take place at the same time are termed Burst activity. Parallel activity. Critical path. Merge activity. Independent activity.

If a project has more than one activity that can begin when the project is to start, a common start node should be used to indicate a clear project beginning on the network. Without a common start node, each path is a Multiple start path. Confused path. Parallel path. Critical path. Dangler path.

When completing a backward pass, you carry the LS to the next preceding activity to establish the LF, unless the next preceding activity is a burst activity, in which case you select The largest LS of all its immediate successor activities to establish the LF. The smallest LS of all its immediate successor activities to establish the LF. The average LS of all its immediate successor activities to establish the LF. The largest ES of all its immediate successor activities to establish the LF. The smallest ES of all its immediate successor activities to establish the LF.

Bill is building a project network that involves testing a prototype. He must design the prototype (activity 1), build the prototype (activity 2), and test the prototype (activity 3). Activity 1 is the predecessor for activity 2 and activity 2 is the predecessor for activity 3. If the prototype fails testing, Bill must redesign the prototype; therefore, activity 3 is a predecessor for activity 1. This is an example of Having more than one start node. Looping. Good network development. Conditional statements. Natural network flow.

If, for some reason, the project must be expedited to meet an earlier date, which of the following actions would the project manager take first? Check to see which activities have the most slack Check to see which activities have the highest risk Check to see which activities are on the critical path Check to see which activities cost the least Check to see which activities have the longest duration

Which of the following is true about hammock activities? They are a combination of Start to Start and Start to Finish lags They are used to identify the use of fixed resources or costs over a segment of a project They are activities in which the costs are not subject to change They are an alternative description for the critical path They are highly sensitive

The likelihood the original critical path(s) will change once the project is initiated is referred to as Concurrent engineering. Sensitivity. Flexibility. Resilience. Rigidity.

The critical path in a project network is the Network path with the most difficult activities. Shortest path through the network. Longest path through the network. Network path with the most merge activities. Network path using the most resources.

A(n) _________ activity has more than one dependency arrow flowing from it. Burst Critical path Independent Parallel Merge

On a project network, the activity times are derived from the Work packages. Project proposal. Responsibility matrix. Budget. Organization breakdown structure.

System documentation cannot end until three days after testing has started. This is an example of which kind of lag? Start to Finish Finish to Start Finish to Finish Start to Start Any of these could be correct

The minimum amount of time a dependent activity must be delayed to begin or end is referred to as Cushion. Laddering. Lag. Hammock. Buffer.

Which of the following correctly calculates the late start for an activity? ES - DUR EF - DUR LF - SL ES - SL LF - DUR

________ activities must be completed immediately before a particular activity. Predecessor Parallel Successor Merge Burst

The backward pass in project network calculations determines all of the following EXCEPT Latest time an activity can finish. The critical path. How long an activity can be delayed. Earliest time an activity can finish. Latest time an activity can begin.

When translated into a project network, a work package will become A milestone. An arrow. A critical path. A single activity. One or more activities.

Which of the following will correctly calculate the total slack in an activity? Either LS - ES or LF - EF LF - ES LF - EF LS - LF LS - ES

Tom is responsible for ordering hardware for a custom home his company is building. The contractor installing the hardware is scheduled to start in 5 working days, but the hardware is on backorder and will not arrive for another 9 working days. Fortunately, Tom has 10 days of slack; however, he shares this slack with the hardware installer. He will have to let the contactor know that the hardware will be ready 4 days later than expected and that the slack for the installer has been reduced by 4 days. Tom and the installer share 10 days of Free Slack. Functional Slack. Total Slack. Critical Slack. Shared Slack. Start to Start

The requirement for a freshly poured foundation to cure before beginning construction is an example of which of the following type of lag? Any of these could be correct Start to Finish Finish to Finish Finish to Start Start to Start

________ activities are to be completed immediately following a particular activity. Burst Predecessor Parallel Merge Successor

Which of the following can be used without coordinating with managers of succeeding activities? Float pad Total slack Free slack Slip pad Critical float

The amount of time an activity can be delayed and yet not delay the project is termed Free slack. Float pad. Slip pad. Critical float. Total slack.

Which of the following represents an activity on an activity-on-node (AON) project network? An arrow Both an arrow and a line A line An arrow, a line and a node all represent activities A node

Information to develop a project network is collected from the Work breakdown structure. Budget. Organization breakdown structure. Project proposal. Responsibility matrix.

Which of the following is provided by both the project network and the work breakdown structure? Sequencing Activity duration Dependencies Interrelationships Timing

The forward pass in project network calculations determines all of the following EXCEPT The critical path. Duration of the project. Earliest time an activity can begin. Earliest time an activity can finish. How soon the project can finish.

If testing cannot be completed any earlier than four days after the prototype has been built, what type of lag exists? Finish to Finish Start to Finish Start to Start Any of these could be correct Finish to Start

Which of the following is NOT one of the basic rules to follow when developing project networks? Conditional statements are allowed but looping statements are not allowed Each activity must have a unique identification number An activity cannot begin until all preceding activities have been completed Networks flow from left to right An activity identification number must be larger than that of any preceding activities

A sequence of connected, dependent activities is termed a(n) Activity chain. Parallel path. Path. Path of events. Dependent chain.
