What is a project schedule network diagram?

A graphic representation of recognized dependencies

Match the scenario with the task dependency. Activities are rushed to match a competitor's release date Tasks are scheduled for different days due to limited space for crews Two task activities depend on each other due to legal requirements Tasks are linked to regular milestones required by management

Activities are rushed to match a competitor's release date = External Dependency Tasks are scheduled for different days due to limited space for crews = Physical Dependency Two task activities depend on each other due to legal requirements = Logical Dependency Tasks are linked to regular milestones required by management = Internal Dependency

When is the Gantt chart constructed in relationship to the deliverables and requirements being broken down into activities and tasks?

After (The Gantt chart is constructed after the activities and tasks have been identified.)

Backward pass

In what way can crashing solutions challenge existing resources?

By spreading resources too thin

Can be done at the same time ------------.

Concurrent

In order to understand how long a project will take to complete, the ----------- must be identified.

True or False: Resources must be accurately estimated at the onset of a project because they are difficult to refine later in the process.

False (Resources are identified at the onset and are refined as the knowledge base of a project grows.)

What is the term for tasks when they overlap despite their dependencies?

Fast-tracking (This is an alternative to schedule crashing.)

---------- is the most common relationship between tasks.

Finish to Start (Finish-to-start relationships, in which a successor activity cannot start until a predecessor activity has been finished, is the most common relationship between tasks.)

If an owner reviews the decor after it is purchased, the design will need to be refined with the owner's feedback. This indicates which kind of relationship with the purchasing tasks?

Finish-to-finish (In this case, the approval task happens after the purchase tasks have begun and the actual goods arrive. Therefore, the approval task will finish with the purchase task.)

The purchase of restaurant materials, such as paint, flooring, furniture, and decorations, cannot be done until the design is approved by the owner. What kind of relationship is this an example of?

Finish-to-start (The successor activity, purchasing materials, cannot start until the predecessor is finished. In this case the predecessor is the approval by the owner of the design.)

In order to determine how much a task can be moved around on the schedule without changing the project completion date, the ----------- must be calculated.

Float

-------- refers to flexibility in when an activity can start and finish.

Float Time

Time/days that can be delayed without affecting completion date

Free float

What are ways to access the Text Box function in Microsoft Windows? (Choose all that apply.) From the insert menu From the task ribbon From the format menu From the tools menu

From the insert menu From the task ribbon

How are serial activities performed?

In a single stream of tasks

When laying out the information for a network diagram into the Text Box function, how are task dependencies shown?

Indentation

During the remodeling project of a retail store, several tasks are delayed due to the finishing of the hardwood flooring, which takes three days to become dry enough to be walked on and for other work to continue. What has been introduced to the process?

Lag Time (The delay represented by the finishing of the hardwood floors is an example of lag time.)

-------- is most likely to shorten the overall duration of a project.

Lead Time

In describing a critical path, which is the only critical element?

Length of time

You are managing a project to design and develop a new type of solar battery for a SMARTcar program. A key stakeholder has just called to tell you that the deadline for completion of the project must be moved forward by 30 days in order to be able to introduce the new prototype at an important industry convention. The company president has warned the team that costs must stay within budget. Which of the following is your best course of action?

Move some functions to a future phase. (You do not want the functionality impacted long-term, but you can probably defer some of the functions until a later date.)

Completion date of last activity is later than project required completion date

Negative float

What is a graphic representation for how a project will proceed?

Network diagram

Which of the following provides a visual representation of all the possible concurrent paths through a project?

Network diagram

Which statements are true of crashing costs? (Select all that apply.) Has no downsides Often done as a last resort Plays a part in contingency planning

Often done as a last resort Plays a part in contingency planning

Who is the best party to estimate the time that a task will take?

Person completing the task

What needs to be completed before this work is started ----------.

Predecessor

What is the definition of schedule compression?

Project timeline reduction (Schedule compression is about reducing a project timeline to meet a desired end date.)

A project manager hopes to reduce the critical path of her project by changing some activities from serial to concurrent. Which steps for reducing critical path might help her to achieve this? (Select all that apply.) Eliminating tasks Reviewing task dependencies Reviewing resource availability

Reviewing task dependencies Reviewing resource availability

Hwang has purchased land with plans to begin an outdoor sunflower growing operation. He has determined four tasks are necessary to getting the farm started. To properly sequence the tasks, Hwang will add label nodes to his network diagram. Match the task with the appropriate label node. Securing a stall in the local flower market Planting seeds Purchasing seeds Clearing and tilling the land

Securing a stall in the local flower market = 1.4 Planting seeds = 1.3 Purchasing seeds = 1.2 Clearing and tilling the land = 1.1

Which process do label nodes identify?

Sequence

Can be done in a single stream of tasks -------.

Serial

Limited available resources dictates that a project is done in a single stream of tasks. What type of activity is this?

Serial

In Microsoft Windows, how are the indented activities converted to chart form?

SmartArt function

The painter does painting before the flooring is installed, but also must return after flooring installation to perform final painting touch-ups. What kind of relationship is this an example of?

Start-to-finish (The first task, painting, cannot be completed until the second task, flooring, has begun.)

During the construction of a gas pipeline, as soon as the crew begins digging the trench and creates the start of the pipeline, the laying of the pipe can start. This is the process of filling the trench. What kind of relationship is this an example of?

Start-to-start (Filling the trench cannot begin until the digging of the trench begins, but can begin without the digging being complete.)

Can only be done after this work is completed ----------.

Successor

Supplies Humans Money

What is true of activities or tasks that can be performed concurrently?

They involve different resources.

Difference between finish date of last activity and project desired completion date

Total float

True or False: A project's requirements and constraints are defined both internally and externally.

True (Not just the internal stakeholders, but external parties like government, customers, suppliers, and strategic partners can define the requirements and constraints of a project.)

True or False: Techniques for compressing a schedule include reducing the quality of the work. True

True (Reducing the quality of the work, doing less work, and doing the work faster are three ways to compress a schedule.)

Critical path helps to define a project's ---------.

completion date

In order to consider schedule compression, we must first understand the ----------.

critical path

Reducing the -------- is a way to optimize a ----------.

critical path schedule

Match the action involved with developing the critical path with the appropriate object. deliverables, activities, and tasks dependencies, sequence of events time each task requires concurrent and serial paths estimated time of the critical path
