Lecutre 9 q2

A small group of people with a combination of expertise or skills critical to the project is called the:

• Project manager

• Project team

• Core project team

• Board of directors

What is a work breakdown structure (WBS)?

• A WBS is a heirarchal structured grouping of project elements that organizes and defines the scope of the total project.

• A WBS is a tool used to track the physical breakdown of a structure during demolition.

• A WBS is a system used to organize employee work schedules and shift rotations.

• A WBS is a database used to manage customer complaints and feedback for a business.

Name following key WBS term

____ _______: This is the level at which the project manager can assign resources and track progress without getting bogged down in too much detail. As a rule of thumb, it should be small enough to assign to an individual or small team.

Name following key WBS term

_______ account: This is typically one level above the work package. It is a level where costs are accrued, monitored, and used for management reporting.

Name the following WBS term:

________ package: This is an undefined work package(s) below the control account used for planning known work when work package detail is not yet available. The planning package is a critical component of rolling wave planning.

Estimating cost, time, and resources are inputs into what document?

• Stakeholder Register

• Project Management Plan

• Project Charter

• Project Status Report

Answer explanation

A project management plan will contain the estimates generated from the WBS.

This document will provide a baseline from which to compare ongoing changes as well as making those changes more precise and easier.

Three-point estimates is a tool designed to assist the project manager in getting good estimates for duration, cost, effort, and resources.

• (O + P) / 2 * ML

• (O + ML) / 2

• (O + ML + P) / 3

• (O + 2ML + P) / 4

PERT is a tool designed to assist the project manager in getting good estimates for duration, cost, effort, and resources.

• E = (O + 2M + P) / 4

• E = (O + 4M + P) / 6

• E = (O + P) / 2

• E = (O + 3M + P) / 5

Answer explanation

A three-point estimate and PERT are both estimating practices. Both are tools designed to assist the project manager in getting good estimates for duration, cost, effort, and resources.

A three-point estimate is a simple average used to estimate task durations:

(O + ML + P) / 3 O = optimistic estimate ML = most likely estimate

P = pessimistic estimate

On the other hand, PERT is a weighted average estimate for task durations:

[O + (4 x ML) + P] / 6

You ask your best technical expert to come up with an estimate for the project. He provides you with three estimates. Best case is 80 days; worst case is 140 days and most likely is 100 days. Based on PERT (E = (O + 4M + P) / 6), what is the estimate for the project (rounded to the nearest whole day)?

3 minutes question

• 92 days

• 103 days

• 115 days

• 123 days

Which of the following depicts the project's planned start and end dates and activity durations for each work package?

• Resource leveling chart

• Milestone chart

• Gantt chart

• Project calendar
