Describe the Activity Sequencing process |
Activity Sequencing is the process of identifying dependency relationships between the project activities and scheduling activities in the proper order. |
|
|
Name the two major relationships between dependent tasks. |
A predecessor is a task that exists on a path with another task and occurs before the task in question. A successor is a task that exists on a common path with another task and occurs after the task in question. |
|
|
Name the four types of logical relationships. |
The four types of logical relationships are finish-to-start, start-to-start, start-to-finish, and finish-to-finish. |
|
|
Know and understand the five most commonly used techniques to estimate activity duration. |
Expert judgment relies on the knowledge of someone familiar with the tasks. Analogous or top-down estimating bases the estimate on similar activities from a previous project. Parametric estimates are quantitatively based estimates that typically calculate the rate times quantity. Three-point estimates use the most likely, optimistic, and pessimistic estimates to determine an average estimate. PERT uses the same estimates as the three-point estimating technique, but it calculates an expected value or weighted average estimate. |
|
|
Define the purpose of CPM. |
CPM calculates the longest path in the project. This path controls the finish date of the project. Any delay to a critical path task will delay the completion date of the project. |
|
|
Explain a network diagram. |
A network diagram is used in Activity Sequencing to depict project activities and the interrelationships and dependencies among these activities. |
|
|
Name the two most common ways project schedules are displayed. |
Project schedules are typically displayed as milestone charts or Gantt charts; a Gantt chart is a type of bar chart. |
|
|
Which of the following is not true for the critical path? It has zero float. It's the shortest activity sequence in the network. You can determine which tasks can start late without impacting the project end date. It controls the project finish date. |
2) It's the shortest activity sequence in the network. |
|
|
You are a project manager for a major movie studio. You need to schedule a shoot in Denver during ski season. This is an example of which of the following? External dependency Finish-to-start relationship Mandatory dependency Discretionary dependency |
1) External dependency |
|
|
What is analogous estimating also referred to as? Bottom-up estimating Expert judgment Parametric estimating Top-down estimating |
4) Top-down estimating |
|
|
You are working on your network diagram. Activity A is a predecessor to Activity B. Activity B cannot begin until Activity A is completed. What is this telling you? |
There is a finish-to-start dependency relationship between Activity A and Activity B. |
|
|
What is the most commonly used form of network diagramming? |
Precedence diagramming |
|
|
What are the crashing and fast track techniques used for? |
Duration compression |
|
|
Which of the following is true for float or slack time? |
It's the amount of time an activity can be delayed without delaying the project completion |
|
|
Which of the following is not a tool used to determine a project's critical path? Forward pass Mandatory dependency Float calculation Backward pass |
2) Mandatory Dependency |
|
|
What are the tools used to calculate critical path? |
The tools used to calculate critical path are forward pass, backward pass, and float calculation |
|
|
Activity B on your network diagram has a most likely estimate of 8 days, a pessimistic estimate of 11 days, and an optimistic estimate of 6 days. What is the three-point estimate for this task rounded to the nearest whole number? |
8 days |
|
|
Which is not true for critical path activities? The early start is always less than the late start. These activities are on the longest path on the network diagram. The float is zero. The late finish is always the same as the early finish. |
The early start is always less than the late start |
|
|
You're working on a project in which the time to complete the project has been heavily restricted and funds are short. You have one resource working on preparing six servers for use in a balanced web array. The servers will all look basically alike. What technique can you use to slim down some of the time required to perform this task in the project? |
Fast tracking |
|
|
Your task requires 4 miles of paving, and it will take 30 hours to complete a mile. On a past project similar to this one, it took 150 hours to complete. Which is true about the estimate? The total estimate for this task is 120 hours, which was derived using expert judgment. The total estimate for this task is 120 hours, which was derived using parametric estimating. The total estimate for this task is 150 hours, which was derived using analogous estimating. The total estimate for this task is 150 hours, which was derived using expert judgment. |
The total estimate for this task is 120 hours, which was derived using parametric estimating. |
|
|
Suppose that you're working on a project in which you've established this milestone: "Database servers built and functional." The following tasks are needed to complete this milestone: Task 1: Build three database servers. Task 2: Install database software on each server. Task 3: Validate that software is running correctly. Task 4: Install database schemas from development environment. Task 5: Test that it's 100 percent successful. Which of these tasks would represent the acceptance criteria for this milestone? |
Task 5 |
|
|
All of the following are true regarding milestone charts except for which one? Milestone charts list the major deliverables or phases of a project. Milestone charts show the scheduled completion dates. Milestone charts show the actual completion dates. Milestone charts are commonly displayed in bar chart format.

You' re in the process of developing a project schedule for a new project for which you've just completed the WBS. What would be the smart next step in figuring out what tasks go into the project schedule? |
Develop an activity list. |
|
|
You've defined a task in a project schedule in which your team members will develop an XML application that uses a MySQL back end. Although the data base administrator (DBA) has plenty of experience with Oracle and Microsoft SQL Server, he has never been exposed to MySQL. Which of the following elements will most likely be affected? 1-Resource allocation 2-Task estimation 3-Activity definitions 4-Determining critical path tasks |

Which is the most commonly used logical relationship? Finish-to-start Start-to-finish Start-to-start Finish-to-finish |
1. Finish-to-start |

Define the 3 types of dependencies. |
1. A mandatory dependency is defined by the type of work being performed, and one activity is dependent on another activity. 2. A discretionary dependency is usually process-or procedure-driven and may include best-practice techniques. 3. An external dependency is a relationship between a project task and some factor outside the project that drives the scheduling of that task |
|
|
List and define the 4 Logical Relationships. |
Finish-to-start In a finish-to-start relationship, the successor activity cannot begin until the predecessor activity has completed. This is the most frequently usedlogical relationship and is the default setting for most project-scheduling software packages. Start-to-finish In a start-to-finish relationship, the predecessor activity must start before the successor activity can finish. This relationship is seldom used. Finish-to-finish A finish-to-finish relationship is where the predecessor activity must finish before the successor activity finishes. Start-to-start In a start-to-start relationship, the predecessor activity depends on starting before the successive activity can start. |

Define PERT and how it works. |
"Program Evaluation and Review Technique"
(optimistic + pessimistic + (4 × most likely)) / 6 |

|
How does the 3-point estimate work? |
It's an average of the most likely estimate, the optimistic estimate, and the pessimistic estimate for the activity. |
