Activity dependencies
During a simple home repair project, Eva is planning on putting two coats of paint on her dining room. After the second coat of paint dries, she intends to hang up a picture of her family in the room. The activity relationships described in this example are known as:
A. Soft logic
B. Lag
C. Mandatory dependencies
D. Critical path
Answer: C. Mandatory dependencies
When you have activities that inherently require other activities to be completed, they are called mandatory dependencies, or hard logic. Discretionary dependencies, or soft logic, allow some flexibility and is based on preference. In this example, Eva must finish her first coat of paint before applying the second coat of paint. Then she must wait for the second coat of paint to dry before she can hang up her picture; she does not have any flexibility on the dependencies.
Requirements output
An output of a scope process that links requirements to their origin is called:
A. WBS dictionary
B. Requirements traceability matrix
C. Scope baseline
D. Requirements documentation
Answer: B. Requirements traceability matrix
The requirements traceability matrix, an output of the Collect Requirements process, helps ensure that each requirement adds business value by linking it to the business and project objectives (PMBOK®).
Projects vs. operations
Projects and operations have similarities and differences. Which of following is true?
A. Projects are performed by teams, operations are performed by individuals
B. Projects are temporary, operations are ongoing
C. Projects are planned, operations are executed
D. Projects are limited by constraints, operations are not
Answer: B. Projects are temporary, operations are ongoing
Projects and operations are both performed by teams, are both planned, executed, and monitored and controlled, and are both limited by constraints. However, projects must have an end and operations will not.
Develop Project Charter
You have just been hired as a project manager for a telecommunications company. You are tasked with managing a project that will create smaller cellular phones. The business case for this is based on:
A. Organizational need
B. Strategic offering
C. Social need
D. Technological advance
Answer: D. Technological advance
The business case, which helps determine whether a project is worth the investment, is an input to the Develop Project Charter process. Strategic offering is noise so of the three real choices (market demand, ecological impact and customer request are the other three possible business cases), technological advance is the most accurate.
Procurement process
Part of your project includes the construction of a new room and although it is not your company’s core competency, you decide to perform a make-or-buy analysis. After you conduct your due diligence and make your decision, you will be creating a request for proposal. Which process are you working on?
A. Plan Procurements
B. Select Sellers
C. Conduct Procurements
D. Plan Contracting
Answer: A. Plan Procurements
The four current processes in the procurement knowledge area are Plan Procurements, Conduct Procurements, Administer Procurements, and Close Procurements. Make-or-buy decisions and procurement documents, such as a request for proposal, are performed in the Plan Procurements process.
Monitor and control risks tool
While monitoring and controlling risks on a project, one of the tools a project manager could use compares the amount of the contingency reserves remaining to the amount of risk remaining to determine if the remaining reserve is adequate. This is called:
A. Reserve analysis
B. Performance report
C. Risk audit
D. Variance and trend analysis
Answer: A. Reserve analysis
A reserve analysis is used in parallel to project execution since risks may have positive or negative impacts to the contingency reserve. This ensures that the reserve is neither too high nor too low throughout the project.
Sequence Activities process
As a senior project manager, Jim is asked to review the work of other project managers in the organization. Wendy, a fairly new project manager, is working with her team to sequence activities. One thing Jim should ensure is that Wendy has already performed the __________ process.
A. Develop Schedule
B. Estimate Activity Resources
C. Define Activities
D. Estimate Activity Durations
Answer: C. Define Activities
Although all of the choices are time management processes, only the Define Activities process precedes the Sequence Activities process. The primary output of Define Activities is an activity list, which a project manager must obviously have in order to sequence activities.
Communication channels
Your project team currently consists of you and three others. If you add one more individual to the team, making a total of five people, how many more communication channels will you have?
A. 3
B. 4
C. 6
D. 10
Answer: B. 4
Communication channels are calculated by n(n-1)/2. That means, if you have four people (like the example), you have six channels [4(4-1)/2 = 4(3)/2 = 12/2 = 6]. Alternatively, you can simply draw four dots on a page and draw a line from each dot to every other dot. That may be a challenge if you have, say, a forty person team. Anyway, the question asks for how many more channels. Therefore, if four people have six channels and five people have ten channels, the difference is four.
Most accurate estimating type
Which of the following estimating types provides the most accuracy?
A. Parametric
B. Analogous
C. Bottom-up
D. Top-down
Answer: C. Bottom-up
Bottom-up estimating, which may also be called grass roots, engineering, or definitive estimating, will provide the most accuracy since activities are estimated with the greatest level of detail. However, that level of accuracy comes at a cost. In order to be more accurate than parametric and analogous, it will also take the longest amount of time to create.
Cause and effect
A quality management tool used to determine show cause and effect is:
A. Decision tree
B. Pareto diagram
C. Control chart
D. Fishbone diagram
Answer: D. Fishbone diagram
A Fishbone diagram, also known as Ishikawa Diagram, uses cause and effect to determine how quality is defined on the project.
