According to the PMBOK, Gina will not need the WBS directly, but will rely on the scope baseline.A Work Breakdown Structure (WBS) in project management is a tool that defines a project and groups the project's discrete work elements in

a way that helps organize and define the total work scope of the project. A WBS element may be a product, data, a service, or any combination. WBS also provides the necessary framework for detailed cost estimating and control along with providing guidance for schedule development and control. Answer option A is incorrect. The scope baseline is an input to define the project activities. Answer option D is incorrect. Enterprise environmental factors are an input to define the project activities. Answer option B is incorrect. Organizational process assets are an input to define the project activities.

This is an example of decomposition. Frank and the project team are subdividing the work packages

into smaller, more manageable units

called activities.

The tools and techniques used in defining the activity process are as follows:

Decomposition: It is used to further divide the project work package into a more smaller and

convenient form called activities.

Rolling Wave Planning: It is a form of progressive elaboration planning where the work to be

accomplished in the near term is planned

in detail and future work is planned at a higher level of WBS.

Templates: It is an activity list or a part of the activity list taken from the previous project and used in

a new project.

Expert Judgement: The skilled members in a project team or other experts who develop project

scope statements can help provide

knowledge in defining activities.

Constructability analysis takes into account the location, logistics, resource availability analysis, the average price of general labor in the area, and labor productivity studies from previous similar projects in the area. Constructability analysis is a process that starts in the initial planning phases and persists all over the entire planning cycle and into the implementation phase of the project. Constructability analysis during the planning process examines the methods and cost of installed equipment and materials, technology, site conditions, resources, and related infrastructure. The benefit of constructability analysis is to reduce both the time and cost of a project. Constructability analysis is repeatedly performed throughout the life-cycle of a project in order to optimize cost, plan, and schedule while mitigating risk. It is a very important process that needs to be performed early in planning to allow alternatives to be considered and integrated into the design. Answer option A is incorrect. This comes under the quality assurance phase.

According to the question, you have to use the estimating technique that has a higher

degree of accuracy. The most accurate estimating

technique is bottom-up estimating.

What is bottom-up estimating?

Bottom-up is a cost estimating technique that involves estimating the cost of individual work

packages or schedule

activities with the lowest level of detail. The detailed cost is rolled up (or summarized) to higher

levels for total project

estimates. This summarized data is very useful for reporting and tracking purposes. Bottom-up

estimating provides a

higher degree of accuracy, provided the estimates at the work package level are accurate.

Answer options C, A, and B are incorrect. Parametric modeling and analogous estimating techniques

use top-down estimation model. These

are less accurate than the bottom-up estimation.

What is analogous estimating?

Analogous is an estimating technique that uses the values of parameter, such as scope, cost, budget,

and duration or

measures of scale such as size, weight, and complexity from a previous, similar activity as the basis

for estimation of the

same parameter for a future activity. It is a top-down estimating technique and is a form of expert

judgment. It provides a

lower degree of accuracy than other estimating techniques. This technique is primarily used when

there is a limited amount

of detailed information about the project or program.

What is parametric modeling?

Parametric modeling is an estimating technique that uses parameters, or project characteristics, to

forecast project costs.

It involves a top-down approach and is similar but more accurate than analogous estimating. It uses

historical data and

other variables to calculate an estimate for activity parameters, such as scope, cost, budget, and

duration.

This is also known as a hammock activity, as the SS and FF relationship hangs off of the

activities in the project network diagram.

A hammock activity is a schedule or project planning term for grouping of subtasks that 'hangs'

between two end dates it is fixed to. It

groups subtasks that are not related in the hierarchical sense of a Work Breakdown Structure. It also

groups subtasks that are not related in

a logical sense of a dependency where one subtask must wait for another.

A hammock activity usually refers to report information that is time-dependent and lasts from the

initial to the latest date of the activities it

encompasses. By using a hammock activity, the top management is able to see an overview of the

project without being besieged by details.

Answer option D is incorrect. Finish-to-start is the most common relationship between project

activities in the project network diagram.

Answer option A is incorrect. Project management overhead describes the work that supports the

project objectives, but is not linked directly

to the project deliverables.

Answer option C is incorrect. A subproject is a discrete set of work that contributes to the project,

but branches off the primary project work. A

subcontract portion of the project is an example of a subproject.
