Tom is the project manager for the ABC Construction Company. As part of the project scheduling for the construction of a new office building, he has allotted time for the inspectors of the building structure, as well as electrical, plumbing, and safety into the project's schedule. These inspectors can be considered what type of dependency in the project?
Correct Answer:
D
An external dependency is any nonproject activity that is external to the project but has a direct impact on the project activities. An external dependency may be an inspector or any agency that may have to give prior approval before the project can move forward.
Answer option B is incorrect. Required dependency is not a valid term to describe a dependency.
Answer option A is incorrect. Mandatory dependencies describe the required order in which the project work must take place - such as foundation before framing, or the operating system installed before the application may be installed.
Answer option C is incorrect. Discretionary dependencies describe the optional order of the project work, such as painting the walls before installing the carpet.
You are the project manager for the GRT Project in your organization. You have created your time duration estimates based on historical information, but the estimates are not holding true in your current project. Unfortunately, many activities are late. You have decided to create a PERT estimate with your project team for each of their activities. What is the formula used for PERT?
Correct Answer:
C
PERT uses the formula of (O+4M+P)/6 to predict the duration of the project activities and the overall project schedule. Three-point estimate is a way to enhance the accuracy of activity duration estimates. This concept is originated with the Program Evaluation and Review Technique (PERT). PERT charts the following three estimates: Most likely (TM):
The duration of activity based on realistic factors such as resources assigned, interruptions, etc. Optimistic (TO): The activity duration based on the best-case scenario Pessimistic (TP): The activity duration based on the worst-case scenario The expected (TE) activity duration is a weighted average of these three estimates: TE = (TO + 4TM + TP) / 6 Duration estimates based on the above equations (sometimes simple average of the three estimates is also used) provide more accuracy.
Answer option A is incorrect. This is not a valid formula.
Answer option D is incorrect. This almost describes the three-point estimate, but does not answer the question about PERT.
Answer option B is incorrect. This is the formula for the three-point estimate. Note the PERT, while similar, uses 4M and divides the result by six factors.
Gary is the project manager of the NGH project for his organization. He and the project team have created the initial WBS. Before Gary and the project team begin creating the activity list, Gary wants the project team to help him create a unique numbering system for the deliverables identified in the WBS. What numbering system can Gary and the project team apply to the WBS to identify the components of the WBS?
Correct Answer:
A
The code of accounts is a hierarchical numbering system that uniquely identifies each deliverable of the WBS and segments the WBS by levels of numbering.
Answer option C is incorrect. Component numbering is not a valid term for project management.
Answer option B is incorrect. A chart of accounts is a financial tracking and assignment tool for common deliverables and activities an organization performs for its customers.
Answer option D is incorrect. Activity linkage sequencing is not a valid project management term.

Contracts Organizational process assets
Your organization wants to start a new project. The study shows that the new project will save organization approximately $200,000 per year. Now it is required to move forward with the project. Which of the following documents will define the project justification?
Correct Answer:
B
The project charter defines the business needs, the project justification, the current requirements, and the new warehouse your organization wants to create. The project charter is the document that formally authorizes a project. The project charter provides the project manager with the authority to apply organizational resources to project activities. According to PMBOK Guide, the project charter should address the following information: Requirements that satisfy customer, sponsor, and other stakeholder needs, wants and expectations Business needs, high-level project description, or product requirements that the project is undertaken to address
Project purpose or justification
Assigned Project Manager and authority level Summary milestone schedule
Stakeholder influences
Functional organizations and their participation Organizational, environmental and external assumptions Organizational, environmental and external constraints
Business case justifying the project, including return on investment Summary budget
If required, it also authorizes the next project phase, and updates the charter. The project manager should always be assigned prior to the start of planning, and preferably while the project charter is being developed.
Answer option C is incorrect. The decomposition of the project scope results in the project's Work Breakdown Structure (WBS). The work packages of the WBS will help the project manager and team create accurate time and cost estimates.
Answer option A is incorrect. The feasibility study is usually created before the project scope, though not always. This document defines the likelihood of the project being able to reach its objectives.
Answer option D is incorrect. The project scope defines all that the project should complete.
